摘要
对苯产品中的烃类杂质含量与苯的馏程之间的相关性进行研究。结果表明 ,当苯中烃类杂质含量在一定范围内时 ,根据毛细管色谱法对苯中烃类的分析结果 ,可以准确地反映出苯馏程是否合格 ,从而提出了以苯中烃类杂质含量的测定取代苯馏程的测定。使苯馏程分析由经典的蒸馏法改为毛细管色谱分析法 。
The experimental data were analyzed by regression analytical method and the relation between the quantity of impurities and the boiling range of benzene was demonstrated It was proved that when the quantity of hydrocarbon impurities was within certain limits, the quality of benzene fractions can be determined by analyzing the hydrocarbon impurities in it So the distillation method for analyzing benzene boiling range may be replaced by capillary chromatography for analyzing the hydrocarbon impurities The practical applications support the above suggestion
