Title: Can I use Denatured Alcohol as Ethanol?
Post by: laclogan on May 22, 2020, 02:59:52 PM
Hey guys, I'm going to buy some Ethanol to use in a video synthesis I'm about to shoot but there's a lot of alcohol makers in my country so the government doesn't approve sellling pure ethanol anymore instead they sell denatured ethanol which contains denatonium benzoate in small portions so what I'm asking is can this denatonium ruin my reaction? thank you in advance.

Ah, song as old as time with reagent alcohol. Depends on precisely what reaction you are trying to do!

Well thanks for the answer and I'll use it as an extraction solvent but I think I should do a little research about Denatonium first. If that doesn't work then I might have to produce ethanol by myself using the sugar recipe lol hope that turns out well! thanks again

denatonium benzoate is a bitterizing agent - quaternary ammonium cation and benzoate anion.  Has a horribly bitter taste.

If you distill the ethanol it will leave the denatonium behind.

Other forms of denatured have small proportions of other alcohols (methanol and isopropanol IIRC) or other solvents.  Possibly those would not interfere with your experiment.
