摘　　要：以费托合成产物C_(9-11)、C_(10-13)、C_(14-16)馏分段、二苯醚和液体SO_(3)为原料,以SO^(4-)/ZrO_(2)固体超强酸为烷基化催化剂,经过烷基化、磺化、中和制备了3种不同链长的烷基二苯醚双磺酸钠(C_(9-11)MADS、C_(10-13)MADS和C_(14-16)MADS),并对其电喷雾质谱进行了表征。测定了3种MADS的耐盐性、耐碱性、表面张力、润湿性能、泡沫性能、与阳离子表面活性剂的配伍性等性能。结果表明:三者的耐盐性无显著差异,耐碱性相同;临界胶束浓度按照C_(9-11)MADS>C_(10-13)MADS>C_(14-16)MADS顺序依次降低,在临界胶束浓度时的表面张力按照C_(9-11)MADS<C_(10-13)MADS<C_(14-16)MADS顺序依次升高;三者的润湿性能、起泡和泡沫稳定性无显著差异;C_(9-11)MADS与阳离子表面活性剂十二烷基三甲基氯化铵配伍稳定性最好。Three sodium alkyl diphenyl ether disulfonate(C_(9-11)MADS,C_(10-13)MADS,C_(14-16)MADS)with different chain length were prepared through alkylation,sulfonation and neutralization using C_(9-11)、C_(10-13)、C_(14-16)distillation sections of Fischer-Tropsch synthesis product,two phenyl ether and fuming sulfuric acid as raw materials,and solid superacid SO_(4)^(2-)/ZrO_(2)as alkylation catalyst.The products were characterized by electrospray mass spectrometry.The salt resistance,alkali resistance,surface tension,wetting performance,foam performance,and compatibility with cationic surfactant DTAC of three kinds of MADS were measured.The results showed that salt resistance of MADS with different chains has no significant difference;the alkali resistance of these MADS has no significant difference;the critical micelle concentration(CMC)of MADS decreases in the order of C_(9-11)MADS>C_(10-13)MADS>C_(14-16)MADS,and surface tension at cmc increases in the order of C_(9-11)MADS<C_(10-13)MADS<C_(14-16)MADS;the foam performance of MADS has no significant difference;the stability of the mixed solution of C_(9-11)MADS and DTAC is better than that of C_(10-13)MADS,and C_(14-16)MADS with DTAC.
