Make Concentrated Ammonia

In this video we make ammonia gas and dissolve it water from various chemicals easily accessible to the amateur.
The first method is merely boiling household ammonia solution that's domestically available from the local supermarket. The ammonia boiled out is lead into cold water where it can be dissolved. While this did work the yield was quite low at around 2.5g per 100mL of household ammonia solution. From the 600mL of ammonia solution used only about 15g was obtained.
The second method was to revisit the classic method to produce sodium nitrate from ammonium nitrate and sodium hydroxide by dissolving them both separately in water and then mixing them together and trying to boil out the ammonia. This worked terribly and i got almost no yield at all.
The third method that seemed to work the best was to react urea and sodium hydroxide in water. This reaction was well-behaved, steady and easily performed with domestically available chemicals. Starting from 200mL water, 90g urea and 120g sodium hydroxide, about 38.6g of ammonia was obtained.
I intend to use the ammonia in a future project to make nitric acid.

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. ^^

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.

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.

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... 🤷‍♂️

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....

Would bubbling ammonia into an aqueous solution of sodium hydroxide cause the sodium hydroxide to precipitate out?

@obst3085 3 жыл бұрын

Sodium hydroxide dissolves unbelievably good in water (over 25M; over 1kg/L water). This makes up for a high hydroxide concentration in the solution, hindering the dissolving of the ammonia gas (NH3) which is driven by is dissociation into ions. As there are so many OH- ions, it can't dissociate into NH4+ / OH- and thereby not dissolve well. In contrary, adding sodium hydroxide to a ammonium salt (as shown) releases ammonia gas. In an alkaline solution (extra NaOH or concentrated NH4OH), the ammonia is actually mostly undissociated (NH4OH), which causes the strong smell as this decomposes more easily to "free" gaseous NH3 and water. In conclusion: No, precipitating NaOH is almost impossible, especially not in that way. Hope this helps!
