摘要
本文采用两种玉门石油磺酸盐的混合物作表面活性剂,在85—250目的石英砂填料柱上作色谱分离,以水作洗脱剂,定量地将石油磺酸盐全部洗脱,从而在没有永久性吸附的条件下对色谱分离现象进行了考察。测定了各组份的平均分子量,研究了不同组份对相行为和混合临界胶束浓度的影响。研究结果表明:石油磺酸盐色谱分离后的各个组份的相行为和混合临界胶束浓度之间有明显的差异。
Chromatographic fractionation of a mixture of two grades of Yumen petroleum sulfonates, sample MI, has been investigated on a quartz-filled column with particle size 80-250 mesh. The sample introduced is eluated from the columm practically entirely. This means that the chromatographic fractionation of petroleum sulfonates could be studied without any permanent adsorption coexisted. The concentration-eluent volume curves show that various components in petroleum sulfonates dilfer in their adsorption and elution behavior. Four fractions obtained at definite eluent volumes have been studied and give quite different phase behavior and CMC values though their average molecular weights do not differ much from each other. The polarity of the composing componeats and their synergistic action appear to be the determining factors in the chromatographic fractionation of petroleum sulfonates.
