Use
Propylene oxide is an excellent low-boiling solvent and raw material of organic synthesis, being able to be used for the preparation of propylene glycol, glycerol, propylene glycol, polyester resin, foam and surfactants. It can also be used as the solvent of cellulose acetate, nitrocellulose and resin solvents. Propylene oxide can react with ammonia to produce isopropanolamine (monoisopropanolamine, diisopropanolamine and triisopropanolamine). Isopropanolamine is alkaline, being able to absorb acidic gas, widely used in gas purification such as the desulfurization of synthetic ammonia industry and decarbonation.
