It should be distilled and/or neutralized and crystallized from bacterial and eel crapola. Not rocket science.

I completely understand. You see, the day I posted this was the day I had joined the blog, and I hadn't taken the time to learn about all it's
features, or search to see if anyone else had posted something similar. So yes, I was being lazy, and I apologize. Beforehand I had done some research
on Google and I found many different results. Some methods where very complicated, and to top it off there where many different ones. The reason I
posted this was because I didn't understand why they had to be so complicated, and I wanted to see what the people on this forum knew about the
process. I'l be sure to check next time I post a topic like this.

The following has been said in some other of the various acetic acid related post.
In some countries it is the most OTC2AcOH I know:
Stuff:
1.) Try to get the 25% vinigar essence stuff. If you can't common vinigar is ok
2.) Get soda (Nacarb. bicarb. fuck just something that bubbles away)
3.) Get sodium-hydrogensulfate (Dry Ph- from pool supply or at some
hardware stores)
4.) Get a ceramic cooking pot or a microwave glass pot or similar
Process:
- Put the vinigar into a big vessel and add soda in preferable small portions
under stirring until fizzing suddenly stops. For any 100g of pure AcOH you need
approx 88g of dry Na2CO3
2AcOH + Na2CO3 + nH2O => 2NaOAc + (n+1)H20 + who cares
- Put that solution into the cooking pot and boil away the water. Make it really
hot.If it turns into a slurry, 'stirr' manually until it is pretty dry. If you just let it
dry witout stirring, you'll likely get a unusable rock. If you use 5-6% vinigar its
maybe better to use 4 vessels. One for each heating plate. That will speed up
the drying by a factor of 4, so it gets as fast as when u use the 25% stuff...
NaOAc + nH2O = > NaOAc
- let cool.
- Mix with an equimolar amount or with a little excess of the PH- pool stuff
to get a well mixed powder.
- Heat this in a distillation apparatus. The AcOH will get over pretty dry.
* Warning: Maybe* there is a potential risk of braking glass here in the
last step. To be honest, I never tried this last step with glassware but
used a metal-can based destilation app. like the one Organikum builded
in his benzene thread.
NaOAc + NaHSO4 => Na2SO4 + AcOH
- If you want it more dry, you are lucky because you just made the drying agent,
too. In that case dry the the sodium-sulfate, by first make it a powder, then
put aluminium wrap on a hot plate an put the NaSO4 on there.Again make it
really hot and stop when dry
Add 'some' of it to your AcOH and let sit for a few hours. Then filter it off.
If you try this and use glassware,please tell me if it went good for you.... At least
the remaining sodium sulfate isn't *that hot...

Ah yes, the old ‘malt vinegar concentrate’, real horrible stuff you’ve to dilute to get ‘real malt vinegar’. Certainly a lot stronger than
table vinegar in terms of [HOAc]. Not as OTC though. Try catering suppliers…
