Propylene oxide (PO) is the third largest propylene derivative except polypropylene and acrylonitrile. It is an important basic organic chemical synthesis raw material, mainly used for the production of polyether and propylene glycol. It is also the main raw material of the fourth generation detergent non-ionic surfactant, oilfield demulsifier, pesticide emulsifier, etc. Epoxypropane derivatives are widely used in automobile, construction, food, tobacco, pharmaceutical and cosmetic industries. It has produced nearly 100 kinds of downstream products and is an important raw material of fine chemical products.
Developed for the first time of propylene oxide, carbon dioxide and methanol synthesis of dimethyl carbonate reaction is of highly active and stable KOH / 4 a molecular sieve solid catalyst, the reaction temperature and catalyst active component of KOH load factors effect the performance of the catalyst. Under the optimized experimental conditions, propylene oxide can completely transform, the yield of dimethyl carbonate is 16.8% from experimental results that the product dimethyl carbonate by carbon dioxide and propylene oxide and addition, propylene carbonate, and then the ester exchange reaction with methanol generated, Methanol is a cocatalyst for the synthesis of propylene carbonate from propylene oxide and carbon dioxide.
Propylene oxide is mainly used for production of polyether polyols, propylene glycol, etc., all kinds of nonionic surfactant of polyether polyols is the production of polyurethane foam, insulation materials, elastomers, adhesives and coatings and other important raw materials, all kinds of nonionic surfactants in oil, chemical, pesticide, textile, daily chemical and other industries widely used.At the same time, propylene oxide is also an important basic chemical raw material.
