Propylene Carbonate

Propylene Carbonate Properties

Propylene carbonate is a colorless transparent liquid, easy to dissolve in water and be mixed with ether, acetone and benzene. Propylene carbonate is a high quality polar propylene carbonate solvent.Propylene carbonate is an organic compound, a cyclic carbonate of propylene glycol. Propylene carbonate liquid is useful as a polar, aprotic solvent. Propylene carbonate exists as two enantiomers but is often used as the racemic mixture. 4-Methyl-1,3-dioxolan-2-one is a byproduct of the synthesis of poly propylene carbonate from propylene oxide and carbon dioxide. Propylene carbonate can be intentionally manufactured from the same feedstocks, using different reaction conditions. Propylene carbonate can be also synthesized from, e.g., urea and propylene glycol over zinc-iron double oxide catalyst.
Propylene carbonate application:

Propylene carbonate PC is used in a variety of syntheses and applications as a polar, aprotic solvent.Polypropylene carbonate has a high molecular dipole moment, considerably higher that those of acetone and ethyl acetate. PC propylene carbonate is possible, for example, to obtain potassium, sodium, and other alkali metals by electrolysis of their chlorides and other salts dissolved in propylene carbonate. 1,2-Propanediol carbonate is specially used for absorbing natural gas and carbon dioxide in petrochemical plant and as plasticizer, textile solvent and alkene and aromatic hydrocarbon extracting solvents.
