Organic Chemistry Lab Demo: Distillations

[@XxXxDEX8914xXxX]

Thank you so much for posting these videos, I'm a visual learner and when it comes to these labs, it absolutely sucks trying to make something of the text that describes the techniques. Seeing it makes so much more sense. Keep it up!!

[@stanleycjohn]

im really thankful for this guy. Im that guy that can make an A in any science class but is a complete idiot in lab no matter how many times i read the procedure. Thank you God!

[@jayliu7786]

i like this video, so much easier to understand than reading the lab text. it's a great explanation and visual. going to be doing this tonight in organic chemistry;)

[@slfudct]

Awesome. All the points of distillation are covered within 10 minutes. Thanks for this upload.

[@scivislab]

We are glad you liked it!

[@SaintWilliamIII]

Very nice explanation of the procedures as well as the reasoning behind them.

[@Kosztorys]

I'm training to be A scientific glassblower and know nothing about chemistry or how the glassware I make is used. This is GOLD!

[@melodyjoon]

thanks you so much...i always watch your videos before taking my organic chem practical ,it really helps :)

[@lucasharrell5182]

Thank you for making this! Very helpful in the Ochem lab!

[@cmatrix4761]

That...is so freakin' cool. I've been trying to figure out why my glassware kept "sticking" and this makes a lot of sense.

[@starkyliam]

Not many people like chemistry, but it's really cool. I enjoyed this video :)

[@Reilly444]

My lab manual doesn't have any illustrations to go along with the text, which sucks because I'm a visual learner; this helped immensely. Thank you.

[@dancalvano8702]

Thanks for the video man. Very informative and transparent

[@scarmenl]

The water jacket creates a cooler surface for the vapor to return to liquid against. The liquid from the water jacket does not get in the distillate because it has its own in an out points to direct the cooling liquid.

[@Bakugantsuvai1]

Thank you for the video it helps me understand for the seperation techniques part of my chemistry test.

[@inazumayuyu8352]

Thank you for this!

[@jameshanson7295]

This helped with my assignment a lot. Thank you for the great help

[@Chlorate299]

Technically that is a vacuum distillation setup. Just attach a hose from a vacuum pump to the nipple on the elbow connecting the condenser to the round bottomed flask and off you go. Also use vaseline for the ground glass fittings, his method of putting two dabs 180 degrees apart is over-complicating it, just a light smear will do it, just don't get it right on the bottom edge. 2 months late...but I hope that helps.

[@gunyolk55]

Hey man, nice video. Nice touch with the bibliographic info on the side.

[@Ideas6696]

These videos are great. It would also be helpful to see a list of supplies typed so I could take a pic for lab. Thanks!

[@Kidwai03]

Doing Distillation tomorrow! Perfect video, thanks :D

[@wrjamescom]

@purplemutantas Alcohol is made by fermentation. But while that's the end product for beer and wine, distilled spirits, be it whiskey, moonshine, etc. are just that, distilled! The video shows exactly the process used to extract the pure alcohol from the mash and make booze. Distillation doesn't make anything, it's used to extract one liquid from another with a different boiling point.

[@purplemutantas]

@KittyRokher You don't make alcohol with this type of setup. Distillation just evaporates a liquid and condenses it back into a liquid. Distillation doesn't make anything. Alcohol is made by fermentation. As far as what to put in the main flask. It all depends on what you want to distill.

[@nick11927]

brings back memories

[@s091511]

THX，i'M GOING TO DO ARRANGE THIS SET IN THE NEXT TUESDAY

[@davidpartyka7561]

Great explanation of distillation...I will link to this video at Test Boost Inc. to help students prepare for the SAT Subject Test in chemistry

[@sandcrab132]

That's a very interesting vocation.

[@jadescott1672]

Thank you very much! Very helpful and informative

[@즈이로그]

12년전 실화냐 잘 보고 갑니다~ nice video!

[@nirashrov1071]

Thank you so much! it has been super helpful :)

[@TheResumeKid]

this was pretty awesome, thanks mang

[@BelaTang]

AWESOME! This vid really helps wth my HW

[@ZachMReichert]

I love this guy.

[@CATHartemis]

I love your videos !

[@scivislab]

Believe me, we did try a lab coat, but the studio lights were so intense that our instructor shone like a fluorescent bulb, ruining the whole frame. We tried *three* different shirts until we decided to go with this very unprofessional-looking shirt, which worked the best with the lights.

[@hmqlostris]

If you are using proper ground-glass glassware (quickfit), the joints don't usually have to be greased.

[@petalcharm]

Very helpful. Thank you.

[@crudeoilsystems]

This was done well. The black background is a good idea..

[@poulettegarcia234]

very helpful thank you!

[@hung14nguyen]

thank you for the tutorial!

[@evlmnkybtr]

Amazon has really good glassware for sale. I just bought a condensing coil and a sep funnel for pretty cheap.

[@MariusSemeonOrtiz]

Wow, thanks for video explanation :)

[@98JMA]

@krazykanadian6 A cow would be used when you want to collect more that one fraction, but don't want to disconnect the receiving flask briefly and attach another - you simply twist the cow for a new small container for a new substance.

[@Omnicurious]

good stuff. i really want one of these. heating mantles are SOOOO expensive.

[@banjobear3867]

I got a few for under 100$

[@lulusan4496]

This was great in fact but had he been louder it'd would've been perfect!

[@MariusSemeonOrtiz]

@ drgergens2: I understood points 1 & 3 you made. Please could you further explain points 2 & 4? For 2. I understand the risks involved in heating a closed system - pressure could build up and BAM glass in your face! To avoid this what you do? Open up the system to allow gas pressure to escape? If you do this however, won't you lose some of the desired products? For point 4. what is distilling to dryness? Also, (this may be a stupid question) but won't boiling chips contaminate substances?

[@Tahmelapachme]

i thought you put on the water tubes before (!) adding the cooler to the apparature to prevent it from breaking whe you push on the tube ends. still an interesting video :)

[@MsFrancis012]

so helpful

[@purplemutantas]

@erikerik666 Google liebig condenser. The wikipedia article that pops up will explain how the water jacket (liebig) condenser works.

[@vmelkon]

For fractional distillation, do you need a vigreux column of different lengths depending on what liquids you are boiling or is the same 30 cm column used in ALL cases? How do you control temperature along that column? Perhaps a more complex glassware is needed for fine control.

[@richardleston5237]

So when you heat glass it freezes :p Just kidding, very informative. Thanks

[@emilysaysmeowx3]

Hahahaha

[@CR7TheBoss]

Fuck you

[@frank88407]

Thank you so muchhhhh

[@spotlightman1234]

@gallonofpcp Yes, but there are cheaper distillation methods.

[@iwuvpies]

omg thank you so much for this video it was so helpful!!!! xD

[@manadarkmagiciangirl]

thx 4 the lesson gr8 help;p

[@mastasheo]

So am I correct in saying this is the safest way to heat flammable liquids. I'm looking to boil ethanol but would like any tips for safety. Also would I have to worry about a possible explosion of the glass?

[@noora3408]

lou try using anti- bumping grindes before you start to prevent any explosion 😊

[@Blaisem]

Without knowing why you want to heat flammable liquids or boil ethanol, you can safely distill ethanol. It's where all the "triple distilled" liquors come from.

[@angeldefilipina]

How is the simple distillation apparatus adapted for fractional distillation?

[@RobotBadger]

Why use a glass thermometer? Can you not use an electronic one?

[@MrProton8]

Erm, please I want to know the functions of the water inlet and outlet on the condenser.

[@salm980]

So what happens when the solution boils too fast? (Not steady).

[@Yadgyu]

Did he add a boiling chip to that round bottom flask? He is going to get localized heating!!!

[@kamalpakdaman4230]

Hey. Nice video. Though I have a serious comment on " fractional" part. !! Isn't that supposed to be like a fractionation column? If yes, then the output of that condenser should go back to the column and have a circulation. Otherwise how in hell you gonna get to distill more than a single stage distillation ?? I'm chemical engineer if it helps to know !!

[@Blaisem]

The condenser makes the vapors into a liquid, which is more dense. Gravity pulls the dense liquid downward into your product flask. How is it supposed to go back into the vigreux column? The vigreux column has a similar effect as a separation column, but the underlying mechanism is not based on polarity or size.

[@oooTDLooo]

Hello, what kind of grease can i use? I used vaseline but it melted down and vapors were escaping.

[@oooTDLooo]

thanks

[@Srslyblack]

can someone please explain about the vacuum adapter? is it ok to leave it open? does air get it, or the vapor get out?

[@hotcayle]

how would I do a similar setup to chill a liquid but not distil?

[@tomcarey5938]

I don't understand the tubes. Do you pump water in one of the tubes?

[@ClownWhisper]

Tommy Carey since the op doesnt seem to care enough to answer questions I will. Yes you pimp water though them. I dont bother with pumps. My setup is near a laundry tub and I got a cheap hose. and cut it short. Then I siliconed some latex tubing into the house . Done and done. very easy

[@cyrek9529]

+Tommy Carey u put water so it cools down the steam and turns it into water :)

[@PirateMate309]

+Tommy Carey I was extremely confused about this as well. The condenser tube itself is double-walled. The innermost cylinder is a continuous tube from side-arm to bent adapter. The outside layer of glass encloses a closed portion outside of this inner, condensing cylinder. It is within this enclosed layer that water can flow in and out of, absorbing heat and facilitating condensation of vapors. I hope this was somewhat clarifying.

[@amberpearson1483]

does the size of the flask matter

[@pelule02]

you inverts the tubing

[@MrMaypole14]

If he pushes up his glasses one more time, I'm gonna scream!

[@almonzowilder4091]

so ... nothing in the heating mantle?

[@banjobear3867]

U ever use H²SO⁴ to greasy it?

[@FuryApple]

Grease? I don't think so. Grease may made your compound contaminated.

[@iammegan6626]

What is he saying about the Water jacket condenser? Sorry if it is obvious, I cant understand him.

[@Blaisem]

The water comes in on the bottom and goes out at the top. That's about it. He says you don't need to grease the bottom but mistaking that doesn't really make a difference.

[@casensy]

No labcoat?

[@meanshoes]

What kind of grease is it?

[@k12rswow]

What kind of grease?

[@bradmetcalf5333]

What type of grease is that? Wouldn't you run the risk of contamination?

[@yungmophead]

At the end of the video, it says not to do it too close to the edge to avoid contamination

[@bradmetcalf5333]

thanks. Realized that after I posted. Premature postalation

[@username6333]

It turns vapor into liquid by cooling it down...

[@joeyjojojr.shabadooiiiesq.3736]

Will the silicone grease enter the final product? For example, I am making a distillate of some edible essential oils. I don't want to be eating silicone

[@Ruebacca]

don't use grease or chemglass sells Teflon sleeves that prevent the joints from sticking.

[@MrItsthething]

You can also use plumbers' teflon tape which you can buy at the hardware store. Don't use it above 200 degrees C.

[@Blaisem]

It won't enter. Even if it did, it won't evaporate with the desired product. The point of distillation is to remove impurities after all.

[@MATEOTL86]

to grease, or not to grease. that is the question.

[@maddclicker]

Water jacket is why.

[@NZman747]

Homework what about test ? :o

[@parshwagada8435]

Lei begs condenser

[@mparsonage53]

SHAVE ARMS MAY CATCH FIRE!!!!!

[@ojb512]

This guy reminds me of "kyle," except he's not acting...

[@brandenreynolds3608]

ô

[@drgergens2]

VERY UNSAFE!!! You added your ethyl acetate but you didn't add a BOILING Chip to prevent BUMPING. Extremely unsafe!!!! Also you did not go over safeties! 1)never fill rbf more that 2/3rds full, 2) never heat a closed system, 3) never for get to add a boiling chip 4)never distilled to dryness. Glad to see you are where safety glasses. YOU"LL need them when your simple distillation set-up explodes in your face.

[@Nighthawk7091]

Chemistry is for nerds.

[@badpharma461]

FAIL - never proceed with an unsupported vessel. PLASTIC Joint-clips are NOT secure. Try that setup in any UK lab and you will be out the door inside 30 seconds. Maybe this is why we see US undergrads dying in preventable lab accidents? I look forward to the methyl fluorosulfonate synthesis... I think 3000 miles is an appropriate distance, given that even basic tasks are not taught correctly. FOOF, ClF3 & (CH3)2Hg in your own time on your own continent please.

[@stevehacker1654]

Pussy

[@joseantoniopazos4100]

y do people make vids like this.....

[@Elektrochemistry]

You forget only to add boiling stones to prevent 'bumping', but I see you have much clamps that would also fix the job. The type of grease doesn't mind but don't add to much of it! (I use vaseline)
