两种重烷基苯磺酸盐的制备及界面性能研究

摘要

以苯、C16～C19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C16～C19重烷基苯；分别以C16～C19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（C1619 HABS、工业HABS）。经测定，发现二者界面性能相近。%Heavy alkylbenzene (C16~C19) was synthesized using benzene and the mixture of alkenes and olefins (C16~C19). 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 C16~C19 heavy alkylbenzene (C1619 HAB) and industrial heavy alkylbenzene (HAB), respectively. Interfacial tension measurements show that these heavy alkylbenzene sulfonates possess the similar interfacial properties.
