Abstract:

The hydroesterification of acetylene with methyl formate catalyzed by nickel-supported catalysts without any corrosive halide promoter has been comprehensively studied in a fixed bed reactor under various conditions. This reaction can be particularly useful since methyl formate may act as a source of methanol-carbon monoxide, thus simplifying transport and handling^[1-3]. The catalysts were prepared by wet impregnation of γ-Al₂O₃ support with NiCl₂ aqueous solution, then dried at 120℃ and calcined at 500℃
