摘　　要：为了研究不同结构的支链烷基苯磺酸钠的分子结构与其表面活性之间的关系 ,以苯或烷基苯、酰氯及溴代烷为原料 ,经过酰化、格氏反应、氢化还原、磺化等步骤 ,合成了 6种分子结构明确的纯的支链烷基苯磺酸钠 ,并用核磁共振碳谱、傅里叶红外光谱对合成的化合物进行了表征 ,并分析了其高效液相色谱图。用Wilhelmy -Plate法测定了部分支链烷基苯磺酸钠水溶液的表面性质 。Six kinds of sodium branched-alkyl benzene sulfonates were synthesize d from benzene or alkylbenzene,acyl chloride and n-alkyl bromide for study ing correlation between structural difference of alkyl benzene sulfonates and their surface-activity.Friedel-Crafts acylation,Grignard reaction,Pd-catalyzed h ydr ogenation,sulfonation and neutralization were conducted during synthesis.Syn th esized products were characterized by 13 C NMR and IR.HPLC of alkyl b enzene sulf onates was also investigated.Interfacial tensions of some sodium branched-alky l benzene sulfonates were determined at air/water interface in NaCl solution usin g Wilhelmy-Plate method.
