    • A process for preparing a synthetic petroleum sulfonate comprising (a) reacting a first amount of at least one aromatic compound with a first amount of a mixture of olefins having from about 8 to about 100 carbon atoms, in the presence of a strong acid catalyst; (b) reacting the product of (a) with an additional amount of at least one aromatic compound and an additional amount of strong acid catalyst and, optionally, with an additional amount of a mixture of olefins selected from olefins having from about 8 to about 100 carbon atoms, in the presence of a strong acid catalyst, wherein the resulting product comprises at least about 80 weight percent of a 1,2,4-trialkylsubstituted aromatic compound; (c) sulfonating the product of (b); and (c) neutralizing the product of (b) with an alkali or alkaline earth metal hydroxide or ammonia.
    • 一种制备合成石油磺酸盐的方法,包括(a)在强酸催化剂存在下使第一量的至少一种芳族化合物与第一量的具有约8至约100个碳原子的烯烃混合物反应; (b)使(a)的产物与另外量的至少一种芳族化合物和另外量的强酸催化剂反应,和任选地与另外量的烯烃混合物反应,所述烯烃选自约8至约 100个碳原子,在强酸催化剂存在下,其中所得产物包含至少约80重量%的1,2,4-三烷基取代的芳族化合物; (c)磺化(b)的产物; 和(c)用碱金属或碱土金属氢氧化物或氨中和(b)的产物。
