Gas chromatographic method was applied to determine the mixture of extraction benzine, benzene, toluene and ethyl acetate vapours. These are the components of several types of butapren glues. Optimum parameters of separation and estimation of those solvents were obtained with 10% Carbowax 20 M on 80 -- 100 mesh Chromosorb W column. Charcoal adsorption method with CS2 elution was used for air samples collection. In addition, a method was presented for extraction benzine calibration with solvents distilled from OBT-III Butapren glue.
采用气相色谱法测定萃取汽油、苯、甲苯和乙酸乙酯蒸汽的混合物。这些是几种丁腈橡胶胶水的成分。在80 - 100目Chromosorb W柱上涂覆10%的聚乙二醇20M，获得了这些溶剂分离和测定的最佳参数。采用二硫化碳洗脱的活性炭吸附法采集空气样品。此外，还提出了一种用从OBT - III丁腈橡胶胶水中蒸馏出的溶剂对萃取汽油进行校准的方法。
