Glycerol is a colorless, viscous liquid sweet clarity. Odorless. There are warm sweetness. Commonly known as glycerin, absorb moisture from the air, soluble in ethanol, miscible with water, not soluble in chloroform, ether, carbon disulfide, benzene, oils. but also absorb hydrogen sulfide, hydrogen cyanide and sulfur dioxide. Insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oils. The relative density of 1.26362. Melting point 17.8 ℃. Boiling point of 290.0 deg.] C (decomposition). Refractive index 1.4746. Flash point (open cup) 176 ℃. Acute toxicity: LD50: 31500 mg / kg (rat oral). Glycerol backbone component is a triglyceride molecule. When the human intake of edible fats, where triglyceride metabolism through decomposition, formation of glycerol and stored in fat cells. Therefore, the final product of the metabolism of triglycerides is glycerol and fatty acids. Used as solvents, lubricants, pharmaceuticals and sweeteners.
