两种重烷基苯磺酸盐的制备及界面性能研究

Preparation and interfacial performance of two heavy alkylbenzene sulfonates

以苯、C（16）-C（19）重烷/烯烃为原料,以氢氟酸为催化剂,在烷基化中试装置上合成了C（16）-C（19）重烷基苯;分别以C（16）-C（19）重烷基苯、工业重烷基苯（烷基苯装置副产物）为原料,在磺化中试装置上合成了两种重烷基苯磺酸盐（C（1619）HABS、工业HABS）。经测定,发现二者界面性能相近。

Heavy alkylbenzene（C（16）-C（19）） was synthesized using benzene and the mixture of alkenes and olefins（C（16）-C（19））. Hydrofluoric acid was used to catalyze the alkylation reaction in the pilot plant. Two kinds of heavy alkylbenzene sulfonates were obtained by the sulfonation of C（16）-C（19） heavy alkylbenzene（C（1619）HAB） and industrial heavy alkylbenzene（HAB）, respectively. Interfacial tension measurements show that these heavy alkylbenzene sulfonates possess the similar interfacial properties.
