Introduction
Glycerol is a colorless, sweet, clear and viscous liquid. Odorless. There is a warm sweet taste. Commonly known as glycerin, it absorbs moisture from the air, as well as hydrogen sulfide, hydrogen cyanide and sulfur dioxide. Insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oil. Relative density 1.26362. Melting point 17.8℃. Boiling point: 290.0°C (decomposition). Refractive index 1.4746. Flash point (open cup) 176℃. Acute toxicity: LD50: 31500 mg/kg (rat oral). Glycerol is the backbone component of the triglyceride molecule. When the human body ingests dietary fat, the triglycerides are metabolized and broken down in the body to form glycerol and stored in fat cells. Therefore, the end products of triglyceride metabolism are glycerol and fatty acids. Can be used as solvent, lubricant, pharmaceutical and sweetener.
