摘　　要：安息香缩合反应以氰化钠或氰化钾为催化剂,虽然产率较高,但催化剂毒性大,易造成环境污染,损害人体健康。采用分步浸渍法合成了以ZSM-5为载体的含Ni杂多酸催化剂,结果表明:用分步浸渍法能得到含Ni的系列杂多酸催化剂;所有的系列杂多酸催化剂均具有较高的反应选择性;Ni-H4[SiO4(W2O9)4]/ZSM-5的反应转化率最佳。Sodium cyanide or potassium cyanide is usually used as a catalyst for the benzoin condensation reaction.Although its yield is high,the catalyst is highly toxic,easily causing environmental pollution and damaging human health.The Ni-containing heteropolyacid catalysts supported by ZSM-5 were synthesized by step-by-step impregnation method.The results show that a series of heteropolyacid catalysts containing Ni can be obtained by a stepwise impregnation method,all series of heteropolyacid catalysts have high reaction selectivity,and the reaction conversion rate of Ni-H4[SiO4(W2O9)4]/ZSM-5 is the best.
