摘　　要：以煤制油费托合成产物C_(10~13)馏分段、二苯醚和SO_(3)为原料,SO^(4-)/ZrO_(2)固体超强酸为烷基化催化剂,经烷基化、磺化、中和反应制备煤基烷基二苯醚双磺酸盐(C_(10~13)MADS),并通过电喷雾质谱证明为目标产物。测定C_(10~13)MADS的耐碱性、耐盐性、平衡表面张力、润湿性能、动态表面张力、接触角和去污性能,并与石油基支链十二烷基二苯醚双磺酸钠(2A1)进行比较。结果表明,煤基C_(10~13)MADS的耐盐性优于2A1,二者的耐碱性无显著差异;煤基C_(10~13)MADS的临界胶束浓度(cmc)高于2A1,γcmc略高于2A1;煤基C_(10~13)MADS的动态表面张力高于2A1;煤基C_(10~13)MADS的接触角大于2A1;煤基C_(10~13)MADS的润湿时间长于2A1;煤基C_(10~13)MADS的去污力低于2A1。Using C_(10~13)distillation section of Fischer Tropsch synthesis product,diphenyl ether and SO_(3)as raw materials,solid superacid SO^(4-)/ZrO_(2)as alkylation catalyst,coal based alkyl diphenyl ether disulfonate(C_(10~13)MADS)were synthesized through alkylation,sulfonation and neutralization reaction.The preparation of C_(10~13)MADS was demonstrated by electrospray ionization mass spectrometry.The salt resistance,alkali resis⁃tance,surface tension,dynamic surface tension,contact angle,wetting properties and detergency properties of C_(10~13)MADS were measured and compared with those of sodium petroleum based branched dodecyl diphe⁃nyl ether disulfonate(2A1).The results showed that the salt resistance of C_(10~13)MADS was better than that of 2A1;alkali resistance for C_(10~13)MADS and 2A1 were the same;the critical micelle concentration(cmc)of C_(10~13)MADS was higher than that of 2A1,and theγcmc was slightly higher than that of 2A1;dynamic surface tension of C_(10~13)MADS was higher than that of 2A1;contact angle of coal based C_(10~13)MADS was higher than that of 2A1,wetting time of coal based C_(10~13)MADS was longer than that of 2A1,detergency of C_(10~13)MADS was lower than that of 2A1.
