The catalytic hydroesterification of methyl formate (MF) with acetylene to methyl acrylate (MA) over nickel-based catalysts prepared by impregnation has been comprehensively studied in a fixed bed reactor at 160～240℃ and under 4～6MPa, GHSV: 630h-1, CO:N2:C2H2=65:28:7. In present work, we have found a catalyst of 11wt%NiO/Al2O3 (80～100 mesh) prepared by wet impregnation with NiCl2 aqueous solution, then calcined in air at 500℃ for 5 h. The selectivity to methyl acrylate and the conversion of methyl formate over 11wt%NiO/Al2O3 catalyst are higher than other catalysts studied in this paper. The optimum reaction temperature for the hydroesterification of methyl formate with acetylene to methyl acrylate is around 220℃.
