摘要
采用气相色谱法分析了高纯氧硫化碳中空气和二氧化碳等杂质 ,以热导为检测器 ,GDX30 3为固定相 ,一次进样可测出空气和二氧化碳杂质含量。最小检知浓度分别为 4 4.5× 1 0 - 6和50 .0× 1 0 - 6。
The production current situation and the development trend of plasticiyer were introduced. The materials current situation of phthalate series such as phthalic anhydride butyl alcohol and octyl alcohol were analyzed. The suggestives for development of plasticizer and industry were raised.
