Isopropanol also called Isopropyl alcohol (MF: C₃H₈O, MW: 60.1) is a colorless, transparent, volatile polar organic solvent with an odor resembling a mixture of ethanol and acetone. It exhibits the chemical properties of alcohols, reacting with acids in esterification reactions and being oxidized to acetone. Dehydration produces propylene. It is non-corrosive to metals (except aluminum, which may react at elevated temperatures). Isopropanol can substitute ethanol as a solvent in many applications, serving as an excellent solvent and chemical feedstock.
