Denatured alcohol
From Free net encyclopedia
Current revision
Denatured alcohol is ethanol with added adulterants that make it useless for consumption as an intoxicating beverage by rendering it toxic or extremely distasteful to drink, but still useful for industrial processes or as a household chemical. This is done in order to make it exempt from taxes that apply to potable alcohol.
Uses
There are diverse industrial uses for ethanol, and therefore literally hundreds of recipes for denaturing ethanol. Typical additives are methanol, isopropanol, methyl ethyl ketone, methyl isobutyl ketone, denatonium, and even aviation gasoline.
One notable use is as a sanding aid, as the alcohol helps to more easily remove the excess sawdust that results from sanding wood. <ref>Template:Cite web</ref>
In this sense of the word, denatured means "a specific property of ethanol, its usefulness as a beverage, is removed". The ethanol molecule is not denatured in the sense that its chemical structure is altered.
