研究了以Zn(OAc) 2 ·2H2 O为催化剂时苯酚和草酸二甲酯酯交换合成草酸二苯酯的反应。采用气相色谱 质谱联用仪对主、副产物进行了定性 ,确定了中间产物甲基苯基草酸酯 ,并对反应过程的模式进行了探讨。考察了催化剂的催化性能及影响反应的因素。采用XRD技术对催化剂进行了表征 ,探讨了其失活原因 The reaction of transesterification of phenol and dimethyl oxalate to diphenyl oxalate with Zn (OAc) 2 · 2H 2 O as catalyst was studied. The main and side products were characterized by gas chromatography-mass spectrometry (GC-MS), and the intermediate methylphenyl oxalate was determined. The mode of the reaction process was also discussed. The catalytic performance of the catalyst and the factors affecting the reaction were investigated. The XRD technique was used to characterize the catalyst and the reasons for its deactivation were discussed
