摘　　要：提出了苯酚和草酸二甲酯酯交换合成碳酸二苯酯反应的终产物碳酸二苯酯和中间产物草酸二苯酯的气相色谱分析方法 ,采用OV 10 1色谱柱基线分离了碳酸二苯酯、草酸二苯酯及其相关化合物 ,外标法定量测定了碳酸二苯酯和草酸二苯酯 ,其相关系数分别为 1.0 0 0 3和 0 .995 0 ;方法的标准偏差RSD分别为 3.42 %和2 .5 8%;回收率分别为 93.3%～ 10 4.0 %和 95 .0 %～ 10 4.0 %;检出限分别为 8.1× 10 - 2 和 7.7× 10 - 2 g L。A gas chromatographic method for analyzing diphenyl carbonate (DPC) and diphenyl oxalate (DPO) is described. DPC and the related compounds, as well as DPO and the related compounds, were well separated through a OV-101 chromatographic column. A good linear relationship of the injection amount versus peak area was observed with the correlation coefficients of 1.0003 and 0.9950, respectively. The RSD, recovery and detection limit for determining DPC were found to be 3.4 %, 93.3 % similar to 104.0 %, 8.1 x 10(-2) g/L, respectively, and that for DPO 2.6%, 95.0% similar to 104.0%, 7.7 x 10(-2) g/L, respectively.
