摘　　要：乙苯是生产苯乙烯单体的原料,苯乙烯又是生产聚苯乙烯及多种高分子材料的重要单体,一般都采用苯和乙烯烷基化制备乙苯,所以准确的分析数据就显的尤为重要。本文正是利用气相色谱,对制备乙苯技术的产物进行了分析研究,建立了气相色谱分析气相和液相组分的方法。通过优化色谱条件,选择最佳色谱柱、升温程序、分流比、载气流速等,以建立一个快速、灵敏、精密度高的分析方法。Ethylebenzene is the material of producing styrene monomer. Styrene is also an important monomer to produce polystyrene and a variety of polymer materials. Generally ethylbenzene was produced by alkylation of benzene and ethylene,so accurate analysis was particularly important. In this article the gas and liquid components were analyzed by gas chromatography to establish a complete method. By optimizing the chromatographic conditions, the best column,temperature program,split ratio,carrier gas flow rate were choosed to establish a rapid,sensitive,high- precision analysis method.
