Making Glacial (95%) Acetic Acid from Vinegar

[@krtm7231]

good tip from my lab - wrap the hotplate in aluminium foil, 1-2 layers. if u spill, it doesnt ruin the hotplate top and is easy to clean.

[@Amateur.Chemistry]

That actually seems lika a pretty good tip, I will try to remember to use is in a future video :)

@Simlatio ah, yes, bromine, famously a thing that people casually pour into things that are sitting on hot plates.

Plus, aluminum is famously unreactive, especially when hot. Also helps give your setup that extra uber-professional look.

@Amateur.Chemistry 12:18 That crystal brick is easily soluble in water with the exception of that black tar or whatever those organic impurities might be. If you want, you can keep that sodium sulfate, recrystallize it, dehydrate it and use as a drying agent for organic solvents. And since you mentioned that you used some sulfuric acid in excess, there is also some sodium bisulfate aka sodium hydrogen sulfate which can substitute sulfuric acid in some reactions.

[@notamouse5630]

If you mix in a little H202 with it, you can dissolve much more copper and form copper acetate, which can grow some lovely dark blue crystals. You can do that with regular vinegar too, but there's a lot of water to get rid of.

That's a good choice of acid due to it's high bp. Phosphoric acid could also be used since that boils at 158°c whereas the glacial acetic acid can be boiled and collected at 118°c. You'd stop collecting as soon as the temp begins to ramp.

[@claimedusername]

[@bromisovalum8417]

Where I live you can buy 80% acetic acid for cheap. I read in a 19th century manual (Dick's encyclopedia of practical processes) that it should be possible to dry 80% or higher acetic acid using anhydrous sodium sulfate followed by decanting and distillation to obtain glacial acetic acid.

[@thecrookedanvil]

@Amateur Chemistry I suddenly had an idea for a video that you could do that no one on KZbin has ever done: you could try to do some dry distillation of nitrogenous organic matter (such as hair, horn, leather, nails, feathers, etc) to try to obtain some ammonium carbonate and ammonium bicarbonate since they are main components of smelling salts and that´s how they were made in past.

[@craigpater6278]

Fascinating chemistry video excellent quality chemistry video very well done sir keep up the good work 👍 also, in South Australia where I live it is perfectly legal to purchase small quantities of glacial acetic acid (purchasing containers up to but not larger than 4 litres) so it's not necessary for me to convert vinegar to glacial acetic acid if I want glacial acetic acid but still excellent quality chemistry video truly fascinating. I think that it's also worth mentioning that despite being considered a weak acid since glacial acetic acid doesn't fully dissociate in water and completely dissociating in water is what defines a strong acid glacial acetic acid is still corrosive and capable of causing severe chemical burns if in prolonged contact with large areas of skin and in addition to being corrosive glacial acetic is also moderately flammable.

It was large enough to land an airplane in. But anyways, they sell cleaning vinegar that is 30% even in the paint aisle! Btw, glacial acetic acid gets its name from "hot ice" which is sodium acetate. Pure acetic acid tends to "ice" up if it sits around for a while.

[@bpark10001]

Can't you use sodium hydroxide for the first step? This eliminates the foaming & math calculations (you add NaOH until pH = 7). Can you use sodium bisulfate for the second step? Sulfuric acid is hard to get in many places & hazardous to handle.

I'm not sure that bisulfate will actually convert sodium acetate will it? I guess maybe it does if the target acid is volatile since it works for nitric. The main reaction is just the first proton of sulfuric acid right?

[@Amateur.Chemistry]

Bisulfate would probably work for this, and when it comes to the sulfuric acid the reaction depends on the temperature, when it is lower only one proton reacts and when it is higher they both react.

[@chemistryofquestionablequa6252]

It works, but you should dry it in an oven first or you can end up with more water in your product, same as with nitric.

[@bromisovalum8417]

It seems to be implemented mostly in countries where terrorism is a problem, if you catch my drift. Before 2014 you could buy concentrated sulfuric acid, 65% nitric acid, 30% H2O2 (even 50% "perhydrol"), pure nitromethane, alkali nitrates and chlorates freely. Guess what happened that they decided to restrict all this draconically?

[@chemicalmaster3267]

@@Amateur.Chemistry I would say that what most likely happened is that vinegar acetic acid tends to have some of its precursor still in it, and so on concentrating it as an acetate salt the leftover organic impurities decompose and form the yellowish brown tint you see the solution or the crystallized solid. It can be sugars from fermenting fruit juices, for example.

Spiced vinegar is not a pure acetic acid solution, which is why the concentrated sodium acetate solution is yellow and the bottoms in the distillation are tarry. Instead, you should use vinegar essence, which is available in every supermarket with a concentration of 25% and is also much purer. You can also get 60, 80 or 100 percent acetic acid easily and cheaply by ordering online. In contrast to concentrated sulfuric acid, which is banned for amateur chemists in the EU (including Poland), glacial acetic acid is not subject to any restrictions. You can also dry distill acetic acid from acetate using anhydrous sodium bisulfate (available as a pool pH reducer in every hardware store), although you may then have to sacrifice the flask for this, because sodium bisulfate melts often cause cracks in the glass when they solidify. To neutralize the acetic acid, I recommend washing soda instead of baking soda, it is cheaper and you only need half as much molar equivalent. Use a clean spatula to add portions; never pour chemicals (even if it is just baking soda) directly from the storage container into the reaction container. Sodium acetate can be safely evaporated and dehydrated in a saucepan on the stove as it does not attack stainless steel, is completely non-toxic and food safe. Drying can also be done in an open baking dish in the oven. The concentration of glacial acetic acid can be roughly determined by measuring the density; titration is more precise, but by no means difficult. It's time for you to get a burette, volumetric flask and measuring pipette... I recommend storing glacial acetic acid in bottles with teflon-lined lids. The fumes creep through all other closures and are not only unpleasant but also corrosive to metals. When lighting glacial acetic acid you have to help a little: a drop of it on the tip of a spatula with sodium peroxide reacts very lively... ;-) No serious coin collector cleans his coins with acid. Rather, he appreciates the patina that forms on the coins over the years. Nordic gold coins gradually acquire a reddish tinge when treated with acid, while copper coins become unnaturally piggy pink. In addition, if organic acids are used and subsequent neutralization/cleaning is inadequate, there is the possibility that an artificial green patina (verdigris) will gradually form. All nightmares for every numismatist!
