摘要： 对比测定了几种有机钛化合物对碳酸二甲酯(DMC)与乙酸苯酯(PA)酯交换合成碳酸二苯酯(DPC)反应的催化性能. 结果表明,乙酰丙酮氧钛(TiO(acac)2)是一种有效的酯交换用催化剂,具有良好的催化性能. 在优化的条件(n(PA)=0.8 mol,n(DMC)/n(PA)=1/2, n(TiO(acac)2)/n(PA)=0.006, θ=180 ℃, t=4 h)下, DMC转化率可达74.9%, DPC和甲基苯基碳酸酯(MPC)的选择性分别可达38.9%和56.9%.

Abstract: An alternative method was studied for diphenyl carbonate (DPC) synthesis from di methyl car bonate (DMC) and phenyl acetate (PA) using a β-diketonate titanium complex, ti tan ium oxide acetylacetonate (TiO(acac)2), as the catalyst. TiO(acac)2 is an ef ficient catalyst for the transesterification reaction with a catalyst amount of 0.006 (mole ratio to PA).

Key words: titanium oxide acetylacetonate, dimethyl carbonate, phenyl acetate, transesterification, diphenyl carbonate
