  This invention relates new and improved processes for the preparation of arylalkylsulfonic acids derived from aromatic or substituted aromatic molecules and AOS acid (generally a mixture of alkenesulfonic acid and sultones, produced from the sulfonation of alpha olefins). The invention involves the use of a superacid catalyst to effectuate the conversion of AOS acid and aromatic reactants to arylalkylsulfonic acid under substantially anhydrous conditions, whereby a substantial improvement in the rate of conversion of the reactants to arylalkylsulfonic acid and/or improvement in mono-alkylation selectivity is realized, as compared to methods of preparation previously disclosed. Also useful as an alkylation promoter is the arylalkylsulfonic acid reaction product itself, produced in situ or from a previous reaction (i.e., a self-catalyst heel). The new processes generally afford arylalkylsulfonic acids with substantially improved conversion yields, highly desirable lighter color, and reduced odor, as compared to previously known methods. The acids produced by the inventive process may be neutralized to form arylalkylsulfonates (i.e., a neutralized form of the acid) which are useful in a variety of end use applications as surfactants and/or emulsifiers.

  本发明涉及一种新的和改进的过程，用于制备从芳香或取代芳香分子和AOS酸（通常是α烯烃磺化产生的烯烃磺酸和磺内酯的混合物）衍生的芳基烷基磺酸。该发明涉及使用超强酸催化剂，在基本无水的条件下促进AOS酸和芳香反应物转化为芳基烷基磺酸，从而实现反应物转化为芳基烷基磺酸的速率和/或单烷基化选择性的显著提高，与以前公开的制备方法相比。芳基烷基磺酸反应产物本身也可用作烷基化促进剂，在原位或从先前的反应中产生（即自催化剂鞋）。与以前已知的方法相比，新的过程通常提供具有显着改进的转化产率、高度理想的较浅颜色和减少气味的芳基烷基磺酸。通过本发明的过程生产的酸可以被中和成为芳基烷基磺酸盐（即酸的中和形式），该盐在各种最终用途应用中作为表面活性剂和/或乳化剂是有用的。

  This invention relates new and improved processes for the preparation of arylalkylsulfonic acids derived from aromatic or substituted aromatic molecules and AOS acid (generally a mixture of alkenesulfonic acid and sultones, produced from the sulfonation of alpha olefins) and to cleaning compositions comprising said arylalkylsulfonic acids. The invention involves the use of a superacid catalyst to effectuate the conversion of AOS acid and aromatic reactants to arylalkylsulfonic acid under substantially anhydrous conditions, whereby a substantial improvement in the rate of conversion of the reactants to arylalkylsulfonic acid and/or improvement in mono-alkylation selectivity is realized, as compared to methods of preparation previously disclosed.
