don't watch to chlorohydrine epoxy chloropropane (ech), is acolorless, volatile oily liquid, has a similar smell of chloroform,mainly for the production of epoxy resin and other fine chemicalproducts, can also be used for drug synthesis intermediate solvent,paper wet strength agent, electroplating brightener, etc. itsingestion, inhalation and skin are toxic, and excitant strong,animal experiments proved to have a potential carcinogen.currently, solvent residue in drug control has been more and moreattention.
        xiangying  eagle analysis technology co., ltd. establishedxingyinggc7990plus headspace - gas chromatography determination ofepoxy chloropropane monomer residue in epoxy resin coating. theresults show that the epoxy chloropropane content in 2.5.500 mu grange, linear equation is x + y = 0.2077 0.2077, the correlationcoefficient of r = 0.9995; method detection limit of 5 mg/kg; theaverage recovery was 91. o % ~ 98.1%; the relative standarddeviation (n = 6) were 1.3% ~ 3.0%. good repeatability of themethod is simple, rapid, and can be used in epoxy resin coatingepoxy chloropropane residual monomer of rapid analysis.
       环氧氯丙烷(ech)别名表氯醇,是一种易挥发的无色油状液体,有类似氯仿气味,主要用于生产环氧树脂等精细化工产品,也可用于药物合成中间溶剂,纸张湿强剂,电镀光亮剂等.其摄取,吸入及皮肤吸收均有毒,且刺激性强烈,动物实验证明有潜在致癌作用.目前,对药品中溶剂残留的控制已受到越来越多的重视.
      滕州市翔鹰分析技术有限公司建立了xingyinggc7990plus顶空-气相色谱法测定环氧树脂涂料中环氧氯丙烷单体残留量的方法。结果表明，环氧氯丙烷含量在2．5．500μg范围内，线性方程为y=0．2077x＋0．3482，相关系数为r=0．9995；方法检出限为5mg／kg；平均回收率为91．o％～98．1％；相对标准偏差（n=6）为1．3％～3．0％。该方法简便、快速，重复性好，可用于环氧树脂涂料中残留环氧氯丙烷单体的快速分析。
