甲酸甲酯与乙烯加氢酯化合成丙酸甲酯

Preparation of methyl propionate from ethylene and methyl formate by hydroesterification

采用钌-碘催化体系,由甲酸甲酯和乙烯加氢酯化合成丙酸甲酯,同时还得到了高附加值的副产物3-戊酮和乙酸甲酯.考察了催化剂组成、溶剂以及反应温度、反应时间、乙烯始压等反应条件对反应的影响.

Methyl formate (MF) was used for ethylene hydroesterification to methyl propionate (MP) by using ruthenium-iodides as catalyst system. In the meantime, the valuable diethyl ketone (DEK) and methyl acetate (MA) were obtained as by-products. The influences of various parameters such as catalyst compositions, solvents, reaction temperature and time, initial pressure of ethylene on the reaction were investigated.
