草酸二乙酯与苯酚酯交换反应产物的气相色谱-质谱分析

Analysis of synthesized products from the transesterification of phenol with diethyl oxalate by gas chromatography-mass spectrometry

采用气相色谱-质谱联用(程序升温)的方法,对MoO3/SiO2催化剂催化草酸二乙酯与苯酚酯交换反应的反应产物进行了分析。结果表明,草酸二乙酯与苯酚酯交换反应生成草酸二苯酯、乙基苯基草酸酯两种反应产物。

The products in the transesterifieation of phenol with diethyl oxalate over MoO3/SiO2 were analyzed by combined means of programmed temperature- capillary gas chromatography - mass spectrometry （GC- MS）. The results indicated that the products of transesterification of phenol with diethyl oxalate were diphenyl oxalate and ethyl phenyl oxalate, respectively.
