Denatured alcohol has no advantages for any purpose over normal ethanol; it is a public policy compromise. As denatured alcohol is sold without the often heavy taxes on alcohol suitable for consumption, it is a cheaper solution for most uses that do not involve drinking. If pure ethanol were made cheaply available for fuel, solvents, or ...
The purity of rectified spirit has a practical limit of 97.2% ABV (95.6% by mass) [2] when produced using conventional distillation processes, as a mixture of ethanol and water becomes a minimum-boiling azeotrope at this concentration. However, rectified spirit is typically distilled in continuous multi-column stills at 96–96.5% ABV and ...

Natural gasoline is often used as a denaturant for fuel-grade ethanol, where it is commonly added volumetrically between 2.0% and 2.5% to make denatured fuel ethanol (DFE), or E98. This process renders the fuel-grade ethanol undrinkable.
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH.It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl.
The word's meaning became restricted to "spirit of wine" (the chemical known today as ethanol) in the 18th century and was extended to the class of substances so-called as "alcohols" in modern chemistry after 1850. [16] The term ethanol was invented in 1892, blending "ethane" with the "-ol" ending of "alcohol", which was generalized as a libfix ...
A study that did not prevent respiratory uptake found that applying 200 mL of hand disinfectant containing 95% w/w ethanol (150 g ethanol total) over the course of 80 minutes in a 3-minutes-on 5-minutes-off pattern resulted in the median BAC among volunteers peaking 30 minutes after the last application at 17.5 mg/L (0.00175%).
