【摘要】 本文描述了变温革取法用三甘醇分离正十二烷和1,3,5—三甲苯时样品的气相色谱分析方法。在获得适合本体系的色谱柱和分析条件基础上,对样品进行了定性、定量分析;并以正戊醇为溶剂,确立了测定常温下体系组分相对重量校正因子的特殊方法。更多还原

【Abstract】 This paper describes the analytical method using gas -chromatography for systems of temperature swing extraction with n-dodecane ,1,3.5-trimethyl benzene and tri-ethylene glycol. After getting chromatographic column and analytical conditions which is suitable for the systems. Proof samples have been treated by both qualitative and quantitative analysises(With n - amyl alcohol as solvent .It stated that special method to measure the correct on factor of relative weight for compositions of system at the normal tempereture.更多还原
