Propylene carbonate Uses
Carbonic acid cyclic propylene ester (CAS NO.108-32-7) is a polar solvent, used as a plasticizer, spinning solvent, water-soluble dyes and plastics dispersant. It can be replaced by phenolic resin as wood adhesives, but also for the synthesis of dimethyl carbonate. Beisdes, Carbonic acid cyclic propylene ester can be used for oily solvent, spinning solvents, olefins, aromatics extraction agent, carbon dioxide absorbent, water-soluble dyes and pigment dispersant.
Propylene carbonate Production
CARBONIC ACID CYCLIC PROPYLENE ESTER (108-32-7) 's producetion.
1. Phosgene the role of raw material propylene glycol with phosgene to generate hydroxyl isopropyl chloroformate, and then reacts with sodium hydroxide, propylene carbonate, and then by vacuum distillation was finished.
2. Transesterification.
3. Chloro-propanol France.
4. Synthesis of propylene oxide with carbon dioxide to carbon dioxide and propylene oxide at 150-160oC , 5MPa reaction under the conditions of propylene carbonate. After decompression fractionation was finished. The above method have been industrialized, but the high cost of the first three methods of production, product quality and poor, which was gradually replaced by a fourth method. 5. Propylene oxide with carbon dioxide to synthesis. This method is developed in the laboratory in recent years as a synthetic method.
