Application of Capillary Chromatography in Benzene Boiling Range Analysis
毛细管色谱法在苯产品馏程分析中的应用研究

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
