nature

A colorless, odorless, viscous liquid. It's sweet. It has strong hygroscopicity. Can absorb hydrogen sulfide, hydrocyanic acid, sulfur dioxide. Can be miscible with water and ethanol, 1 part of the product can dissolve in 11 parts ethyl acetate, about 500 parts ether, insoluble in benzene, carbon disulfide, trichloromethane, carbon tetrachloride, petroleum ether, oil. It is easy to be dehydrated and lose water to generate diglycerol and polyglycerol. Oxidized to produce glyceraldehyde and glyceric acid. It solidifies at O℃ and forms a rhombic crystal with flash. Polymerization occurs at temperatures around 150 ° C. It is incompatible with anhydrous acetic anhydride, potassium permanganate, strong acid, etchant, fatty amine, isocyanate and oxidant.

Safety information:

Glycerin is a relatively safe compound. It is not recognized as a carcinogen or teratogenic and generally does not cause irritation or allergy to the skin and eyes. Prolonged exposure may result in dry skin. When using glycerin, avoid direct contact with eyes and skin, and store in a dry, clean, well-ventilated place. As a chemical, glycerin should be used in accordance with proper operating procedures and safety precautions.
