英文摘要A new palladium/tris(4-fluomphenyephosphine/p-toluenesulfonic acid catalytic system was developed to synthesize methyl propionate from ethylene hydroesterification. The influence of phosphine ligands and acid promoters on catalytic activity was systematically studied. A volcano relationship between the catalytic activity and the electric effect of phosphine ligand was achieved through the characterization of P-31 NMR of selenium phosphine compounds. An acid strength range favorable to the hydroesterification of ethylene was found by characterizing the pKa value of Brunsted acid. Then, the effect of phosphine ligand/Pd(OAc)(2) ratio, p-toluene-sulfonic/Pd(OAc)(2) ratio, temperature, time, and pressure on this reaction were investigated. Finally, the elementary reaction-based kinetic model was developed, which indicated that nucleophilic attack of methanol on the Pd-acyl intermediate to give methyl propionate is the rate-determining step. The activation barrier of rate-determining step is 83.1 kJ.mol(-1).
