英文摘要Novel catalytic systems containing n-butylstannonic acid (n-busn(o)oh) were used to synthesize methyl phenyl carbonate (mpc) and diphenyl carbonate (dpc) by the transesterification of dimethyl carbonate (dmc) with phenol in atmospheric conditions. the catalytic system consisting of n-busn(o)oh and cuprous iodide (cui) had the highest activity for the transesterification. when the reaction was carried out between 150 and 180 degrees c, with a molar ratio of n-busn(o)oh to cui of 1: 1, a catalyst amount 0.005 (molar ratio to dmc), a reaction time 10 h, a molar ratio of dmc to phenol of 2: 1, a dropping time of dmc 6 h, the conversion of phenol was 67.2%, and the selectivity of mpc and dpc was 40.2 and 59.6%, respectively. upon comparison of the activities of cu2o, cux (x = cl, br, 1) and the catalytic system being composed of n-busn(o)oh and cu2o/cux, it was found that cu2o and cux were excellent promoters, and the stronger was the anion electronegativity in the promoter, the weaker was the promoting catalysis of the promoter.
