1·The status of VCM and acetylene gas recovery by pressure swing adsorption in vinyl chloride production units were introduced.

介绍了在氯乙烯生产装置中，采用变压吸附工艺回收精馏尾气中的VCM和乙炔气的情况。

2·With vinyl acetate as reactant in place of acetylene and its derivates in 1, 3 dipolar cycloaddition, the target product was obtained successfully.

在此步反应中成功地以醋酸乙烯代替乙炔及其衍生物作为环合试剂进行了1,3 -偶极环加成反应，得到了目标产物。

3·The amine hydrochloride is subsequently reacted with acetylene in the presence of mercury free catalysts to produce vinyl chloride.

再将有机胺的盐酸盐与乙炔反应，在非汞催化剂的作用下生成氯乙烯。

4·This method was simple, rapid and accurate. The relative standard deviation and recovery were 4.0% and 99.5% respectively for vinyl chloride, and 4.6% and (99.8%) respectively for acetylene.

该方法简便、快速、准确，测定的氯乙烯相对标准偏差、回收率分别为4.0%、99.5%，乙炔相对标准偏差、回收率分别为4.6%、99.8%。
