摘　　要：以对叔丁基苯酚、甲醛、苯酚、无水三氯化铝、浓硫酸、正溴代烷等为原料,经缩聚、脱烷基化、磺化和醚化反应,合成了一系列水溶性杯[4]芳烃烷基醚磺酸钠(烷基分别为—C4H9,—C6H13,—C8H17,—C10H21,化合物依次命名为1-C4,1-C6,1-C8,1-C10)。借用傅里叶变换红外光谱仪,表征了中间体和最终试样结构。用染料法对试样进行了表征,表明试样均为负离子表面活性剂。用滴体积法测定表面活性剂水溶液25℃时的表面张力,各试样分别能将水的表面张力降至32.06,34.96,42.35,45.35 mN/m;临界胶束浓度分别为1.26×10-3,0.32×10-3,1.78×10-3,1.20×10-3mol/L。Water - soluble calix [ 4 ] arene alkyl - ether sulfonated sodiums （alkyls were -C4H9, -C6H13,-C8H17,-C10H21,named 1 - C4,1 - C6, 1 - C8, 1 - C10 respectively）were synthesized with p - tert- butylphenol, formaldehyde, phenol, anhydrous aluminum chloride, sulfuric acid and n - bromoalkane as materials via four- steps involving polycondensation, dealkylation, sulfonation and etherification. The intermediates and final products were characterized by FTIR. The products were qualitatively identified by dye method, and proved to be anion oligomeric surfactants. The surface tensions of dilute aqueous solutions of products were measured at 25 ℃ by drop - volume method. The surface tension of 1 - C4,1 - C6,1 - C8, 1 - C10 was 32.06,34.96,42.35,45.35 mN/m,the critical micelle concentrateion of the aboved oligomeric surfactants was 1.26×10^-3,0. 32×10^-3 ,1.78×10^-3, 1.20×10^-3 mol/L.
