I got some 70% denatured alcohol but now I hear it is deliberately poisoned with methanol to prevent consumption (what kind of asshole would do such a thing is beyond me). Do you know of any way to get a solution of just ethanol, without methanol, from common shops?

if it is methanol, it can be removed using fractional distillation.

if that term is unknown to you then research is needed to not kill yourself. if you don't know, you likely do not have the skills required.

i do not advocate this method. try brewing your own alcohol. it is stupidly easy once you know how to do it and you can make 18% alcohol for like $1/liter

an easy way to do it is to get EC1118 yeast and add it to water that has been boiled with the sugar.

my equation based off of experience is [desired alcohol content]x20x[final volume in liters] = [total grams of sugar needed]

for example 21L of 18% alcohol would require 21L*20*18=7560g of sugar.

you can add fruit or juice or whatever to make it taste better. research brewing for the rest of the details.

18% is probably a bit high without the turbo yeasts, the highest % i've managed was 15% with a very good yeast. But you can get up to around 30% with freeze distillation (fractional freezing)

  1. mix water, yeast nutrients, tomato paste and citric acid
  2. make yeast starter
  3. add yeast to the sugar sludge
  4. build still while waiting for fermentation and settling to complete

or just order non denaturated hooch on the internet

To my knowledge, methanol doesn't form an azeotrope with ethanol. Anhydrous samples can be distiled and collected that way. If it's 30% methanol, you can just distill out 30ml of a 100ml sample and it should be fine once the temperature reaches 75C
