what is the chemical formula for grain alcohol
To get 100% pure alcohol, benzene has to be added, and then distilled again. In spite of this extra distillation some benzene will remain so it's not safe for consumption. When Grain Alcohol is 95% pure, it is 190 proof. The chemical formula is C2H5OH. Grain Alcohol differs from vodka in that vodka is more diluted, and charcoal filtered. It's not usually used in mixed drinks of any quality, though college students will often mix it with fruit drinks to make a cheap punch, particularly in garbage-can size quantities.
