碳酸二甲酯生产技术研究

Technology Introduction of Dimethyl Carbonate

简述了光气甲醇法、酯交换法、甲醇羰基氧化法、尿素醇解法、二氧化碳甲醇直接合成法等碳酸二甲酯生产工艺,对不同生产工艺进行了比较,尿素醇解法因生产成本少、装置投资小,具有很大的发展空间。

@@@@Some methods are used for the synthesis of Dimethyl Carbonate, such as phosgene alcoholysis, transesterification of propylenecarbonate or ethylenecarbonete, methanol oxy-carbonylation, urea transesterification and CO2 direct alcoholysis ect. And the economy of these methods are compared. The results showed that the process of urea transesterification is preferable because of least cost.
