Hi everyone -
It's a bit difficult in some states to get pure ethanol. Most "denatured alcohol" contains more than 15% of other alcohols, MIBK, and other impurities. Some brands are more than 45% methanol. All of these are obviously unsuitable for making methyl esters, diethyl ether etc.
In short, I have been looking for ways to get tax-exempt, pure, absolute, 200-proof EtOH, without paying the tax for drinking alcohol or needing special exemption forms to get it from a chemical supplier.
I have found something very close. Perfume-grade alcohol is denatured with the SDA-40b scheme, which is by weight:
99.88% EtOH
0.12% t-BuOH
0.0006% denatonium benzoate
The t-BuOH is of inconsequential concentration for most reactions and the denatonium benzoate can be distilled out.
A bulk buy would be great for this since I can get a case of 4 gallons for about $160, coming in at $40 per gallon. you'll never find that anywhere online, and I will redistribute "at-cost" plus shipping and whatever the container costs, which shouldn't be more than a dollar or two.
Anyway, if there is interest for more than 5 gallons I can fill out the paperwork and get the government permit to get more than 5 gallons per year, and resell to you guys as long as no single person buys more than 5 gallons. Age 21 not required. Let me know if you want some and how much.
