Propylene glycol carbonate,1,2-Propylene carbonate,PC
ISO14001,ISO45001,ISO9001.
Propylene carbonate is a colorless odourless flammable liquid. It is missoluble with ethyl ether, acetone, benzene, chloroform, vinyl acetate, etc., soluble in water and carbon tetrachloride. The absorption capacity of carbon dioxide is very strong and the property is stable. In industry, propylene oxide and carbon dioxide are added under a certain pressure, and then vacuum distillation. It can be used for oily solvent, spinning solvent, olefins, aromatics extractant, carbon dioxide absorbent, dispersant of water-soluble dyes and pigments, etc.
