HMS介孔分子筛催化剂上苯酚氧化羰基化合成碳酸二苯酯
Oxidative Carbonylation of Phenol to Diphenyl Carbonate over Mesoporous HMS Molecular Sieve Supported Catalyst
摘要
Abstract
HMS mesoporous molecular sieves was synthesized with octadecylamine as the template and a novel HMS supported Pd ( Salen) complex catalyst was prepared by microwave-assisted solvothermal impregnation. The complex and the catalyst were characterized by means of FTIR, 1H NMR, XRD and N2 adsorption-desorption. The complex structure was confirmed and the characterization results showed that the Pd(Salen) complex was supported on HMS molecular sieves. The catalytic performance of the supported schiff base complex catalyst Pd( Salen)/HMS in oxidative carbonylation of phenol to diphenyl carbonate ( DPC) was investigated. The effects of reaction temperature, reaction pressure and reaction time on the DPC yield in the oxidative carbonylation were studied. The DPC yield was 18. 8% under the appropriate reaction conditions of reaction temperature 373 K, pressure 4.0 Mpa(n(CO) : n(O2) 7 : 1 )and reaction time 8 h.关键词
