Propylene Carbonate, with molecular formula C₄H₆O₃ and structural formula is a colorless transparent liquid. Its melting point is -48℃ and boiling 238.4℃. It can be solved in water and carbon tetrachloride and well mixed and solved with diethyl ether, acetone and benzene etc. As a highly effective agent, Propylene carbonate is used to get rid of carbon dioxide in petroleum vapor , oil splitting gas, casing head gas, synthetic ammonia, plasticizer, textile agent or dispersant of water soluble dye and pigment, oil solvent and extraction agent of alkene and aromatic hydrocarbon, excellent medium in lithium cells industry and solvent of polymers. Moreover, PC can be used as a fine carbonization agent in producing carbonates
