When Home Depot still had it, they had denatured alcohol and fuel alcohol. Is there a difference? I know the denatured is roughly 50% ethanol and 50% methanol. What do they do different for the fuel version?
It's been 50 years since my last college chemistry course. I sort of remember some chem students taking methanol and propanol from the lab and using some process to make a passable ethanol - which, after testing for purity, then ended up in the punch bowl at a dry campus party.
