Synthesis of Diphenyl Carbonate by Oxidative Carbonylation of Phenol with Pd/CuO-Ce_(0.5)Mn_(0.5)O_2 Catalyst
Pd/CuO-Ce_(0.5)Mn_(0.5)O_2催化剂氧化羰基化合成碳酸二苯酯

CuO-Ce0.5Mn0.5O2 support was prepared with two CuO doping methods and used in direct synthesis of diphenyl carbonate by oxidative carbonylation of phenol. 0.5%Pd/CuO?Ce0.5Mn0.5O2 catalyst was prepared through precipitation method using PdCl2 as the precursor of active Pd component. The catalyst was characterized by XRD, SEM and BET techniques. The effects of preparation methods of support on the activity of catalyst were investigated. The catalytic activity test results showed that the physical structure of...
