Synonyms Glycerin generally refers to glycerol
C Triol, called glycerin in the national standard, is colorless, odorless, sweet, clear and viscous liquid in appearance, and is an organic substance. Commonly known as glycerin.
C Triols, which absorb moisture from the air, can also absorb hydrogen sulfide, hydrogen cyanide and sulfur dioxide. Insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oil. Glycerol is the backbone component of the triglyceride molecule. Relative density 1.26362. Melting point 17.8℃. Boiling point 290.0℃ (decomposition). Refractive index 1.4746. Flash point (open cup) 176℃. Acute toxicity: LD50: 31500 mg/kg (rat oral). [1]
