Characteristics and Applications
Propylene Glycol, with molecular formula C3H8O2and structural formula,is colorless transparent liquid. Its meltingpoint is -59.5??? and boiling point is 187.3, and can be mixed orsolvent with water, alcohol and several organic agent. Propylene glycolis a raw material for producing unsaturated of plasticizers, dehydrant,surface active agent, firming agent and binder. Moreover, PG can beused as antiseptics, ice inhibitor and moisture preserver of tobacco.
