This is fantastic. Really interesting see exactly how essential oil is made. As a typical lay customer of essential oils, it makes me really appreciate the number of steps involved in extracting just a few millilitres of oil. Nice work, my friend.

[@Glattuh]

The moment the technology is able to reproduce the sense of smell when you watch a video, I think you will be pleased that I uploaded that :D I can tell you its poisonus (which, far away from fiction, the oil is skin and eye irritant and toxic by ingestion) is balanced with the good smell it has. It is just like lemon (ofc) but very, veeeeery, concentrated (like having 4 lemons in a vial maybe??)

@@Glattuh but you used the skin from 4 lemons, which is less the 4 whole lemons

[@HeartandSoulApothecary]

The collected water that condensed is Lemon Hydrosol which is used in many cosmetic products as well - dont throw that away, as it contains trace amounts of the lemon oil as well. (This is true of all hydrosols)

[@philipstowers4741]

Yeah, I didn't think that was oil. I actually did this with oranges, just to do it, and what I got would evaporate completely, no residue at all. Not really like oil.

[@dakotastorms1255]

I enjoyed watching this video it was nice to see how the process is done and the white noise was a great addition.

[@Pierrot110194]

I know this video is a few years old but I have a few comments on the extraction: You should use a smaller amount of water or a larger separatory funnel, the total volume of liquid is way too much for that size of container. It will also allow you to shake the separatory funnel much harder, giving you a better extraction result per run. Another thing is that you should use at least a quarter of the volume of the aqueuos phase per run. So you would add 100 mL of solvent (hexane) to 400 mL of aqueous phase. You're using way less than would be standard practice. Using a larger amount of solvent will also allow you to lose two or three drops w/o dropping your yield too much, so that your combined organic layers will contain much less water. You should also perform at least three rounds of extraction, this is due to Nernst's distribution law: Use little (not too little) amount of solvent per round and do more rounds; doing it three times with 50 mL will be better than doing it once with 150 mL. If you can get your hands on it, try using DCM or ethyl acetate if the latter dissolves limonene sufficiently I'm not sure. DCM is much easier to get rid of than the hexane; ethyl acetate is way less harmful than both of those. I also would suggest using funnels to transfer liquids. Secondly, since I'm only now watching the full video: You should use an oil bath to boil the water! Never place a flask directly onto the heating plate since this will cause a great deal of thermal stress in the glass because the heat distribution is very uneven. Thermal stress in glass means that it can break, as I'm sure you know. So you could use some mineral oil or vegetable oil (obv. easier to obtain) with a high smoke point and heat that up to about 120 °C so the inside of your vessel will reach 100 °C.

Peter, those flasks used to be made of quartz and you could safely place them on hot surfaces.

[@ladyturantulo]

your house must smell so good after doing this :D

[@Glattuh]

It did yes¡¡¡ What it is also interesting is that the water distilled, where the oil forms a phase above it, does not smell that good. It has some kind of smell like if you boil lemon juice and then drink it (it is difficult to explain, and more in not my language :D ) Check out my other lavender oil extraction :)

Hi¡¡ Well normally seed are used to extract their lipidic fraction (vegetable oils and fats) and contain little to no essential oil. Steam distillation is not usefull to extract this kind of compounds but extraction does¡¡ Fortunately, I have a video extracting the oil from walnuts. The method can be carried out for other seed in high content fo fats like sesame or sunflower.

The fractionation part has some shortcomings. First of all you should not boil the hexane+oil mixture because while doing so some oil would definitely have escaped and Secondly, you should have used Activated Anhydrous Sodium Sulphate or Sodium Chloride to remove water from the essential oil.

[@musicplayer2661]

Nice video though, I think its a good tip if you can peel the zest without getting pith(white color portion). I did it by peeling in thin slices using a slicer and cutting the orange peels to small sizes with a scissor as necessary. Although, my other group got no oil from distill as they peel the orange in large size with the pith. I'm not sure if the normal yield of 4% possible for limonene. I got 2.33% on mine. There was a lot of oil left in the separatory funnel and using the hexane would have help getting a higher yield as water is polar and hexane with oil is non-polar, which in my case, my lab class did not provide us hexane. Also, we used a long-stemmed pipet to draw the oil from water in the separatory funnel and there was no water on the end product as per the IR-spectrum.

[@Glattuh]

Thanks for the comment¡ It feels weird that you didnt get any oil in that batch (with all the peel involved). Citrics give oils with no problem in my experience. I have also tried it with orange, tangerine and grapefruit and they all gave me nice and smelly oils¡ Also, good to know that the oil does not contain any water by IR analysis, I wish I could do some of that inmy channel someday ;D

[@musicplayer2661]

Nation Of Our Hobbies wow I didn't expect a reply, thank you for reading my comment!! It was actually weird that my other group did not get any oil, so we and our instructor assume that it was due to the large orange peels with the thick pith. I haven't actually tried with tangerine, grapefruit, its good to know they gave oil. Also, in our other experiments, when using fractional distills, we used aluminum foil to cover around the fractionating column. Hopefully, you will post more videos of your experiments :O

[@Glattuh]

So we can asume raw material has to be treated before extracting the oil, I will keep that in mind in my next essential oil video. Maybe by reducing it size in a blender before adding it to the extraction flask? I think that is a good idea if the blender can be washed several times with water so little oil remain in the walls of it Talking about other thing, may I ask what are you studying? I am just curious ;D And yes, I have a lot of incoming projects to film in my channel. Hope I can begin by the next year, because I have a surprise that will boost the channelm (Cant talk more about it hehe) ;D

[@michaelboot]

As a 2nd year biobased chemist I was wondering why you added the hexane to dissolve the oil. Oil is insoluble in water so 2 layers would already be formed therefore the L/L-extraction step would be unnecessary in my perspective. I can imagine using hexane for getting a higher yield of final product by washing the aqueous layer with it but the amount of extra oil seemed to be marginal. Am I right?

[@Glattuh]

Yes you are completely right. I used hexane not to extract more oil from the water phase, because as you said, it s insoluble in it, but to wash the remaining that could be in the funnel after draining it. As you see Im working with very small ammounts of oil so every loss will affect a lot in my yield. If I extract more peels and get much more oil I probably would not use hexane, as it is easy to seprate two well differenced and significant ammounts of liquid phases. I wash the aqueos phase several times. That is done both to wash the possible reamining oil in the water and to wash the funnel itself. Im not using the oil for any application already so using hexane was not an issue Seems like every coment from here is about using or not using hexane D:. Many people ask me that. Ill give you upvote for the comment so it should be on top. I hope people read this comment before asking me the same question again haha. Anyway thanks for commenting :D Check out my other videos tooo :)

[@michaelboot]

I see, now I understand. Indeed when the oil isn't used for any health purposes, then hexane can be used as a solvent. However, a comparable solvent like pentane or maybe even better; heptane should do the job as well without risking neurotoxic poisoning.

[@Glattuh]

Yeah I know that too. I could not find pentane or heptane where I buy my other stuff. Appreciate the comment :D

[@birrdsmith9890]

[@world-suppliers]

i have never seen on youtube a quality video like this one , may god bless you and reward you more success , my question : is thete any other way to separate oil from water rather than solvent as i think solvent can affect quality and also the need to heat solvent and oil can effect it too , what is your comments plz

[@Glattuh]

Hey thank you! I trully preciate it thanks. I am working in incoming chemistry videos ;) It can be separated without solvent of course. I used it because it is only a little quantity of it and it is hard to separate it without a smaller separatory funnel but yeah, you can use a graduated cylinder and a Pasteur pippete to separate the oil from water, for example. Using more quantities of lemon peels will give you more oil and that makes the separation easier too. Normally in chemistry its more difficult to "play" with smaller quantities. Thank you for comenting!! NOOH

[@world-suppliers]

thanks dear sir hope you can make for us more video about the sepration of natural elements from plants , returning always to the second part of question does solvent effect the quaiity of essential oil even little abit good countinue and thanks alot

[@Glattuh]

Well, there is always risk when using solvents, so yes it can contain traces of hexane in my case. I will not use it except for having and smelling it so the risk is minimum but if you plan to use it in a perfume or something its better not to use solvents. An alternative for hexane could be heptane wich is not as dangerous as hexane. Anyway the amount of solvent is so low that the risk is minimum or null but, as always in this world, if you plan to use it you have to do at your own risk.

[@Glattuh]

By the way, traces of solvent doesnt really affect the final smell and carachteristics of the oil. Maybe as you said heating it can affect the compounds it has but, it has been heated when it is co-distilled with water at 100C so... Heating at hexane boiling point will not affect much more.

[@world-suppliers]

Nation Of Our Hobbies yes thanks alot o solvent can leave its toxic traces into the essential oil hope also to know if solvent can take of some nutrient value from the oil ; beside i hope that you can also talk about the degree of heating you need to apply and how to keep it satble ects ...i mean do steam extraction need srable heat or variant one and how do we need what each kind of oil nead such dgree of heating ragards

[@Glattuh]

Y3sh just by decanting it. I used hexane because of the small ammount I was workong with. In huge extractors a little bit of essential oil thta remains in the funnel will not affect the yield as much as in small scale like mine

[@elinasnowy9511]

Hi, I tried the steam distillation with lemon skin yesterday(like your video but the apparatus set up are kinda different and I did not do the liquid-liquid extraction). The solution is get is transparent in color but slightly, very slightly cloudy. It has a lemon smell and it smell very great and fresh. Does the solution contain lemon oil and limonene? Sorry if my English is bad.

[@Glattuh]

HI¡ When you say solution you mean the oil, already separated or decanted from the aquaeos solution or you mean the distillate (water+oil)??

[@elinasnowy9511]

The distillate. I carried out the experiment just until the distillation without carrying further separation or liquid-liquid extraction. The distillate appears to be a little cloudy and there isn't any trace of oil on the surface. I was wondering if it contains limonene or essential oil for at least the slightest amount?

[@Glattuh]

Well, it is very rare that you get cloudy distillite with lemons. Usually with lemon distillation you should get two totally inmiscible phases. It is cloudy because your essential oil is in the form of very tiny droplets. If you let it stand for a while they should merge and appear as a floating liquid. And yes of course, you have essentiak oil and for sure it contains limonene. If you cant see any phase appear you have a very little ammount and ti reciver that, you will probably have to use L-L extraction, because you will not be able to perform a decantation.

@@Glattuh my word for today, google: inmiscible- miscibility is the property of two substances to mix in all proportions, forming a homogeneous solution.

This might seam a stupid question but why is the lemon essential oil clear and not yellow?

[@Glattuh]

In fact is a really good question¡¡¡ The oil is composed of a large ammount of different compounds. It is as simple as the compounds which gives the lemon its colour is not co-distilled with the steam during the process. I asume that those compounds or pigments are in majority carothenes and xanthophylls. They size and weight are too large for that, they aren`t volatile, so they are not codistilled with this technique. Thanks for the question¡ :D

[@natashagreen-chillaxedprod7769]

Nation Of Our Hobbies thank you for your swift reply. And that explains a lot thank you 😊

[@azvorinji]

Cold-pressed lemon oil is yellow, if you've seen that somewhere and wondering what that yellow lemon oil was.

[@deaddarknessgameplay6422]

This is a super patient reply. I'm glad that you are entertaining "stupid questions".

[@HatiKeseorangan]

I am new pharmaceutical student here... Thanks for the video... But why hexane ? And it will apply to other stuff To?

[@Glattuh]

Hi. Good to know new scientists come to see my videos!! I am preparing a video for the upcoming 10k subs explaining all of this, because that is question I receive a lot. I could just decant the oil phase using a pipete or something. I used hexane to try to get ALL of the oil that could remain in the glassware inner walls. As I am working with very small quantities, small loses represent high loses in yield so, just because I have Hexane around and I could, I used it haha. As simple as that... Later I saw that it is not quite common in the essential oil world but, me as a chemist... It is daily task, so implanted in a chemist mind that I didnt think about in that moment, as I improvise all of my videos. Thanks for commenting!

Very interesting. thanks for posting.

I've never heard a condenser called a "refrigerator" before. It took me a second to figure out what you were referring to.

[@Glattuh]

Yeah sorry for that, here in Spain we call them "refrigerantes" so the easy translation was that. I knew they were call diferent in english but at the time of editing the video I just didnt realised

[@wartechmachine]

The first time I saw this video with all that chemistry tools, I thought it was complicated. Now I know there is a much simple way to do it with basic kitchen stuff.

[@mikemotorbike4283]

yeah, and all that crazy etc stuff

[@nicolashrv]

Judging by the light on the video probably a lot, but how many hours you were distiling the peels? The rate of watts to oil must be quite high, making it somewhat expensive method? Wouldn't have been more efficient to use a peeler and then chop the skin inside the flask with some kitchen devise, in order to avoid having some of the oils lost in the scratching?

[@Glattuh]

+nicolashrv Yeah, it is not the cheap method, but im not a EOils industrial producer ;). I can not remember how many hours did I use to distill it but maybe 2 or 2:30. And ys someone told me I could use a peeler once, and thats right but I didnt have one by thetime I make this video. Thanks for commenting!

[@jeanpierredaviau7478]

Not really, I have tried it.

[@lilaalkuino7444]

Hello. I'm an incoming 10th grader and our investigatory project is all about disintegrating styrofoam using lemons. Can the oil extracted from the lemon be able to somewhat decompose the styrofoam? if not, are there any other parts of the lemon that can possibly be acidic enough to disintegrate the styrofoam?

[@Glattuh]

Hi!!! Well. The dissintigration of styrofoam is only a break of its structure and not a reaction with acid or bases. It is commonly demostrated by adding acetone (wich is a nonprotic polar organic solvent) to styrofoam (expanded polistyrene) as it breaks the structure of stryrofoam releasing the air bubbles in it and making it colapse into a paste. I think it could work with lemon oil because it has limonene, wich is actually sold in labs as an organic solvent. What is really important to predict the results is looking PS and solvent polarities. So yes I think it could "dissolve" styrofoam. Anyway, I think there is no other organic compound in lemon that could "dissolve" PS.

Essential oil must be liquid gold if the cost of 2 hours of electrical heat and time pissing around is worth it for a few ml of oil.

[@Glattuh]

In fact EO are quite expensive in the market. But think this is done in an amateur way, just to get a few grams of oil, I dont "need" more. I just did it to perform it and show you how I do it.

[@drewgrows7765]

Cost about $10 per ml if high grade

I am considering to make durian essential oil.

[@Glattuh]

Nice! I didnt hear about that fruit, let me know about your results :D

[@Syoma]

Is it possible to make an infusion type of essenstial oil? lets say 4 different flowers?

[@Glattuh]

+syoma fukasaku I dont really know. Essential oils are inmiscible with water but the flavour will be there. Flowers tipically have very low yielda for extraction but it can ve steamdistilled aswelk. By the way if you are planing to drink it dont use solvents for the extraction.
