摘要
采用气相色谱法测定合成碳酸丙烯酯产物中碳酸丙烯酯、水和1,2丙二醇等杂质含量。在检测器TCD、180℃、填充有聚二乙二醇丁二酸酯涂渍的硅烷化102白色担体的不锈钢填充柱上,样品中的组分获得分离。采用校正归一化法进行定量分析,相对标准偏差s小于69%
Propylene carbonate,water and 1,2 propylene glycol in the rectifying products from the synthesis of propylene carbonate were determined by GC with TCD,the analysis were seperated at 180℃ on a 1m×3mm stainless steel column packed with silanized 102 white support coated with polydiethylene glycol succinate.The quantitative analysis was carried out by the rectified area normalization method.The relative standard deviation was less than 6.9%. \ \
