碳酸丙烯酯/碳酸乙烯酯的制备技术研究进展

Advances in preparation of propylene carbonate or ethylene carbonate

介绍了碳酸丙烯酯/碳酸乙烯酯的研究现状,着重阐述了酯交换法、环氧丙烷/环氧乙烷与二氧化碳环加成法及尿素醇解法等制备方法。指出了尿素醇解路线是以尿素为原料,改变现有工业化路线对环氧化合物等石油化工产品的依赖,对开发天然气下游产品的利用具有重要的意义,且具有较好的工业化前景。

The recent developments in propylene carbonate or ethylene carbonate are reviewed,with the emphasis on the preparation method such as the esterchange method,the addition reaction of propylene oxide or ethylene oxide and carbon dioxide,the urea alcoholsis.The urea alcoholsis route uses urea as raw material and does not rely on the petroleum product such as epoxide.It is advantageous for the development of natural gas product,and has better industrialization prospect.
