I once purified 37% ammonia by adding it dropwise (I even used a syringe pump!) to some sodium hydroxide granules, to convert it to the gaseous ammonia, and bubbling the output in pure water. (I wanted it to be free of carbonates). It worked great. So something similar with household ammonia could work too. ^^

I am not a trained Chemist however, I worked in the QC lab at a Ink Manufacture where we used Aqueous Ammonia in solution to liquify Acrylic Resin chip. When added to solution it never created suds. All Ammonia sold in the Grocery stores have surfactants. If your Ammonia forms suds when added into H2o then it's not pure....Your Urea process created Ammonia solution at the concentration we used for liquifying resin so congrats on that. ..Oh and for some reason I miss the smell of Ammonia, To this day 25 years later I can directly smell a bottle of store Amm. and not even flinch.

[@fieroboom]

FYI, if you're looking for larger amounts of Urea than what you find in cold packs, Diesel Exhaust Fluid is just a fairly saturated solution of 45% Urea & 55% water. I would imagine that you can make some fairly concentrated ammonia using DEF & Crystal drain opener without really concentrating or modifying either product. The DEF would contain a little more than the preferred amount of water, and sometimes the drain opener is a mix of KOH & NaOH, but it would be super quick in a pinch... 🤷‍♂️

Thank you! The urea route was stuck in my head since Doug's Lab stated that it would foam a lot when he tried it.

[@sebastianborusinski351]

Hello NR, I actually done succesfully this type of acquiring ammonia. Here's a tip, don't dissolve urea in water and don't use NaOH. Simply heat up the urea. During the process the ammonia gas is formed and urea condenses to form biuret.

[@sriramkompella5728]

Hey NurdRage, you could try the ammonium nitrate method by not using an NaOH solution. Instead, you could try just mixing the two ingredients dry in your reaction flask, and adding an addition funnel with a minimal amount of water. As you said, it is less controllable than the urea method, but it will produce relatively drier ammonia with minimal additional drying steps, as heat is not needed, and will not bring over any extra water. Additionally, with this method you can also produce sodium nitrate as a byproduct, with minimal contaminants, which is an added bonus.

[@Gendo3s2k]

[@jauzijau5037]

Hey man, its pretty easy. Extract the urea. Heat it up in a test tube. Collect the gas. Heatin urea forms NH3 and CO2

[@Polarcupcheck]

One thing I thought was unusual was researcher saying you don't want to let urine degrade into ammonia before applying to a crop, yet, farmers side dress corn crops with anhydrous ammonia. So, I am guessing, you can side dress crops with straight urine.

[@toddkobelljr.2004]

For what can i ask?

[@yesrayell8118]

You can add ammonium nitrate in a egg timer fashion to a slurry of calcium hydroxide and collect the gas with crushed ice. The formed calcium nitrate can then be reacted with sulfuric acid to form nitric acid. In the end that would decompose ammonium nitrate into ammonia and nitric acid and leave a residu of calcium sulfate also called gypsum or ordinary plaster.

[@toddgillespie8165]

Household ammonia with muriatic, then drying out the salt, then recovering the gas with a base always worked fine for me.

Did you try dropwise addition of water?

[@bobwerner6512]

[@matttuck5010]

Awesome video! One question, and one suggestion. Question: Can the solution in a used instant cold pack really be used as fertilizer as is? Can I literally dump ammonium nitrate onto my kale plants? Suggestion: Please, please, please be more specific when talking about heat. You always say you are heating some random solution, but hardly ever say at what temperature! I have a heat plate, but it only reaches 100C, so I need to know which projects I am capable of doing. Other than that, your videos are amazing, I always feel smarter after watching them!

[@brocktechnology]

The temperature is up to the solution. The hotplate has very little to say about it. I'm guessing you think your hotplate only goes to 100 C because you tried it with water. Try it with a can of sand and you'll see what it can really do.

[@timothyegoroff8333]

90 grams urea, + 120 grams NaOH, then slowly drip water into the solution while heating, ammonia gas is released without foaming, also water can be added all at once, but to stop foaming, add anti-foaming agent (2-octanol, polysiloxane or dimethylpolysiloxane) or I use a teaspoon of silicone or mineral oil which can reduce foaming quite a bit.

[@rainwater397]

I was able to get a better yield by saturating a solution of household ammonia with an excessive amount nacl and applying low heat @ 50c. After the reaction quit bubbling and most of the salt was dissolve the solution had almost no ammonia smell and a ph of 7

[@aetius31]

I think using ammonium carbonate (which is sold as baking powder) could be also an option. Either by decomposing it at 50°c or by reacting it with calcium hydroxide.

[@hanelyp1]

With thermal decomposition I expect you'd need to remove the CO2 for most uses, such as by passing over a hydroxide.

[@marshfield01]

Bulk diesel exhaust fluid may be a cheaper feed stock for the last reaction.

[@waltersobchak7275]

Feedstock I remember saying feedstock along time ago.🤔🤔 What you know bout that huh??🌻🐝

[@Jayenh]

So, the urea + propylene glycol + catalyst (I use zinc oxide) => propylene carbonate reaction generates lots and lots of ammonia. Feed it through a gas washer or your other preferred bubbler ... you get a twofer. Also note that the solution becomes less dense as the concentration of ammonia increases, so more room than you might expect is needed.... There might be (probably is) some non-ammonia passing through the bubbler, but I think a lot of it winds up as ammonium carbamate (almost certain) deposited in the reflux condenser and vacuum tubing etc. I'm assuming that something in the mixture is decomposing into something that includes CO2....

[@Electroblud]

Urea is the same stuff they use to burn nitrous oxide to nitrogen and water in modern cars. I believe it is first converted to ammonia somehow before injecting into the converter chamber.

[@andrewmackenzie2638]

mixture of urea and water is injected into the exhaust, the heat causes decomposition - look up "AdBlue"

[@andreyjoshuaantiporta3492]

I think you should bubble the gas to the receiving solution by using a taller container. I recommend using a graduated cylinder as your receiving container and inserting the tube at the very bottom of the cylinder. This improves contact between the ammonia gas and the water - increasing your yield significantly.

[@stephenjacks8196]

May I suggest Ammonium Sulfate and Calcium Oxide (aka Lime). Cheap 25 pound bags in the fertilizer section of Stores. I also used that with acetone to make 2,2,6,6 tetramethyl 4 piperidone. Calcium Hydroxide also works as CaSO4 absorbs water.

[@spiritofage8235]

Household ammonia path: what if saturate it with some salt to knock down solubility of NH3. Preferably NaOH/KOH, they also should bring ton of -OH ions and shift the equilibria towards free ammonia (same as nitrate path, but w/o nitrate, depends what is cheaper to use).

The Sodium Carbonate may act as a bit of a dessicant too. It's rather hydroscopic itself so may reduce the soluability of NH3 in the reaction mixture. That's pretty good in all honesty.

[@ronoxengineering]

ash cooked at an extremely high temperature to form a hydroxide, ideally in the abscence of air. something like a clay pot with ash and coals choked off from the air under another fire or conditions similar to a high quality charcoal kiln is what you need, since you dont want the hydroxide to absorb carbon dioxide and form carbonates, you want monoxide-hot level temps. then you simply mix it with urine which is loaded with urea.

[@PaulOlt1]

IMO, there is a much simpler method. Just mix lime (either calcium oxide or even slaked lime i.e. calcium hydroxide) with ammonium nitrate (fertilizer granules). Needs to be done in a much larger sealed container with a gas tube coming out (to collect the ammonia) and another tube going in (to add the water). Then slowly add just a little water. Both materials are relatively inexpensive and can be bought in large quantities at the local hardware store, so you shouldn't worry about yield. The trick is to add only a little water at a time as the lime will heat up. The remaining calcium oxide will absorb the excess water so you get relatively pure ammonia.

[@kenon2414]

Also calcium carbonate is not soluble in water, so you will have a precipitate that doesn't dissolve in it like sodium carbonate, you have to be careful tho, because it could be so alkaline ammonia could be forced out of the solution
