Method for synthesizing methyl acrylate

摘要

The present invention relates to a novel catalyst composition and a novel process for synthesizing methyl acrylate from methyl formate and acetylene, in which methyl formate reacts with acetylene in the presence of a main catalyst comprising one or more compounds selected from RuCl3, Ni(CH3COO)2, NiBr2, NiI2, NiSO4, Ni(NO3)2, PdCl2, CoCl2, Rh3(CO)12 and RhCl3, and the catalyst promoter comprising one or more compounds selected from CuSO4, NaI, KI and CH3I, at a temperature of 120 DIFFERENCE 240 DEG C., and under reaction pressure of 1.0 DIFFERENCE 10.0 MPa, a molar ratio of methyl formate to acetylene ranges form 0.1:1 to 20:1. The yield of methyl acrylate may reach to 63%.
