Glycerol, also known as glycerin, has a chemical formula of C3H8O3, colorless, odorless and sweet. It has a clear and viscous liquid appearance. It is an organic substance that can absorb moisture from the air, as well as hydrogen sulfide, hydrogen cyanide and sulfur dioxi de. It is hardly soluble in benzene, chlo roform, carbon tetrac hloride, carbon dis ulfide, petrole um ether and oils. It is the skeleton component of triglyceride mol ecules.
