摘　　要：在生产极性化SBS工艺中,需要引入环氧氯丙烷这一重要的中间体,环氧氯丙烷在各环节中的含量,直接影响生产工艺及产品的质量。本文研究试验了气相色谱法在极性干胶生产各环节中环氧氯丙烷的测定,试验结果表明:在一定的色谱条件下,环氧氯丙烷在各生产环节的样品中能得到较好的分离.采用工作曲线法进行定量分析,相对标准偏差为4.7%~6.4%,回收率为98.0%~105%,最低检测限为0.05 mg/L。In the production of polarized SBS,it is necessary to introduce epichlorohydrin,an important intermediate,the content of epichlorohydrin in each link,which directly affects the production process and product quality.In this paper,we have studied the determination of Gas chromatography epichlorohydrin in the production of polar dry rubber.The results show that under certain chromatographic conditions,epichlorohydrin can be well separated in the samples of each production link.The relative standard deviation(RSD)was 4.7%~6.4%,the recovery was 98.0%~105%,and the detection limit was 0.05 Quantitative analysis.
