重烷基苯磺酸盐复配体系的相行为研究
|
摘要
将重烷基苯磺酸盐(HABS 3#)与不同类型表面活性剂复配,乳化后观察其相行为,以考察复配类型及复配比例对相行为的影响规律,为研制乳化型化学驱配方提供依据。实验结果表明,阴离子HABS 3#与少量阳离子十六烷基三甲基溴化铵(CTAB)复配后,能显著增强体系的增溶和乳化性能,复配比例对其相行为影响很大;HABS 3#与同类型的HABS 1#复配后对相态的协同效应相对较小;非离子脂肪醇聚氧乙烯醚(AEO-9)和两性离子椰油酰胺甜菜碱(CAB-35)与HABS 3#形成的混合体系,随复配比例的增大,发生上相→中相→下相的相转换,乳状液由油包水型(W/O)转变为水包油型(O/W);呈中相时,AEO-9和CAB-35的复配比例分别为12%和21%。
Through the phase behavior expeiments on the compounded system of heavy alkyl-benzenesulfonate(HABS 3#)and different types of surfactants,we aimed at studying the effect of different types of compounded system on phase behavior to develop emulsion formula.The results showed that solubilizing and emulsifying property has improved greatly after compounding the anion HABS 3#and little cationic cetyl trimethyl ammonium bromide(CTAB).The proportion of compounding played a great role on the phase behavior.The cooperative effect of the same type about HABS 3#and HABS 1# was relatively weak.The system changed from upper-phase to middle-phase,then to bottom phase with the compound proportion increasing when HABS 3# was compounded with nonionic primary alcohol ethoxylate(AEO-9)and zwitterionic cocamidopropyl betaine(CAB-35).In this process,the type of the emulsion changed from W/O to O/W.The proportion was 12% of AEO-9 and 21% of CAB-35 when the compounded system presented middle phase.
