采用溶胶凝胶法合成了有机无机杂化材料(OIH),通过与PdCl2(PhCN)2反应,制备了固载化PdCl2/OIH非均相催化剂.考察了此催化剂在苯酚直接氧化羰化合成碳酸二苯酯反应中的催化活性,并与均相PdCl2催化体系进行了比较.结果表明,负载型催化剂的催化活性与均相体系相当.当使用Cu2O和四氢呋喃分别作无机助剂和溶剂时,PdCl2/OIH催化剂重复使用5次后,碳酸二苯酯的产率基本保持不变,钯流失量仅为12.3%. The organic-inorganic hybrid material (OIH) was synthesized by sol-gel method and the immobilized PdCl 2 / OIH heterogeneous catalyst was prepared by reaction with PdCl 2 (PhCN) 2. The effect of the catalyst on the direct carbonylation of phenol to carbonation Diphenyl ester.The catalytic activity of the supported catalyst was similar to that of the homogeneous system.When Cu2O and tetrahydrofuran were used as the inorganic and solvent respectively, After repeated use of OIH catalyst for 5 times, the yield of diphenyl carbonate remained almost unchanged, and the amount of palladium lost was only 12.3%.
