I believe a number of different chemicals are used to denature ethanol.
Benzene for one.

And for all you wannabe chemists out there... Denatured alcohol
(ethanol plus a bit of methanol) is available everywhere... I have a
quart stting in front of me on my desk I picked up at the hardware
store... I use it for cleaning my glasses, camera lenses, etc..

Get 100 cc of gasoline, add 10 cc of denatured alcohol from your
favorite Home Depot, etc., add 1/4 tab of "plop, plop, fizz, fizz" and
observe... If it fizzes then you know that the test is valid as your
mixture is "gasohol"...
