Abstract: Using α-C16H32 olefin, SO3 and xylene as raw materials, the product is synthesized by sulfonation, alkylation and neutralization process. The product is characterized by IR and ESI-MS, and their interfacial activity and foaming properties are also evaluated. The IR and MS results show that the synthesized product is dimethyl phenyl hexadecyl sulfonate. The CMC of the product is 0.006 mol/L. The lowest interficial surface tension between the prepared weak base ternary compound system and the crude oil recovered by the Daqing 4th oil field is 3×10-5mN/m. And the interficial tension is lower when sulfonate concentration is lower in the system. The ASP prepared by the product has a good performance in interficial tension stability for three months. The foaming properties of the target product are better in 150 mg/L hard water than that in distilled water.

Key words: weak base ternary compound system, dimethyl phenyl hexadecyl sulfonate, synthesis, interficial activity

摘要: α-C16H32, SO3和二甲苯为原料, 经磺化、烷基化和中和反应合成了二甲苯基十六烷基磺酸钠。采用红外和质谱等手段对产物结构进行了表征, 并对产品的表/界面活性和泡沫性能进行了评价。红外、质谱等表征结果表明合成产物为二甲苯基十六烷基磺酸钠。产物的临界胶束浓度为0.006mol/L;所配制的弱碱三元复合体系与大庆采油四厂原油的界面张力最低可达3×10-5mN/m;90天稳定性实验结果表明, 由二甲苯基十六烷基磺酸钠配制的弱碱三元体系具有良好的界面张力稳定性;其在矿化度为150mg/L的硬水中的起泡性和稳泡性均优于蒸馏水。
