摘　　要：以费托合成产物、二苯醚和SO3为原料,经过烷基化、磺化、中和制备了煤基烷基二苯醚双磺酸盐C10-13MADS。测定了C10-13MADS的耐盐性、耐碱性、表面张力、动态表面张力、润湿性、泡沫和乳化性能,并与十二烷基苯磺酸钠(LAS)进行了比较。结果表明,C10-13MADS耐盐性优于LAS;C10-13MADS耐碱性优于LAS;C10-13MADS的临界胶束浓度(cmc)高于LAS,cmc时的表面张力与LAS无显著差异;C10-13MADS动态表面张力高于LAS;C10-13MADS润湿时间长于LAS;C10-13MADS泡沫体积低于LAS;C10-13MADS乳化能力低于LAS。The coal-based alkyldiphenyl oxide disulfonate(CMADS)was synthesized using Fischer-Tropsch synthetic oil,diphenyl oxide and SO as raw materials through alkylation-sulfonation-neutralization.The salt resistance,alkali resistance,equilibrium surface tension,dynamic surface tension,wetting ability,foam and emulsification of CMADS and dodecylbenzene sulfonate(LAS)were tested.The results were as follows:salt resistance of CMADS was better than that of LAS;alkali resistance of CMADS was better than that of LAS;critical micelle concentration(cmc)of CMADS was higher than that of LAS,and there was no significant difference on surface tension at cmc between CMADS and LAS;dynamic surface tension of CMADS was higher than that of LAS;wetting time of CMADS was longer than that of LAS;foam volume of CMADS was lower than that of LAS;emulsification ability of CMADS was lower than that of LAS.
