PVP-TiO_2双负载Pd-Hg催化邻氯甲苯水相脱氯活性研究

Study on Activity of Dechlorination of o-chlorotoluene Catalyzed by PVP-Pd-Hg /TiO_2 in Aqueous System

研究了在相转移条件下 ,甲酸钠为氢源 PVP-Pd-Hg/Ti O2 为催化剂催化邻氯甲苯水相脱卤性能 .考察了 Pd/Hg摩尔比、催化剂用量对反应的影响 .当 Pd/Hg(摩尔比 )为 1 0∶ 1 ,催化剂用量为 0 .31 0 g时邻氯甲苯脱氯收率为 53.6%。

Catalytic activity of PVPPdHg/TiO 2 for dechlorination of o chlorotoluene was stadied in the presence of phase transfer catalyst and HCOONa as hydrogen resoures.The effect of Pd/Hg molor ratio and the amount of catalyst on the reaction were investigated when Pd/Hg molar ritio was 10∶1,and the amount of catalyst was 0.310g,the yield of o chlorotoluene gave 53.6%.
