IMPROVED PROCESS FOR PREPARING LINEAR ALKYLBENZENE SULFONATES

Disclosed are processes for preparing linear alkylbenzene sulfonic acids and their corresponding salts comprising: (a) treating a linear alkylbenzene with a sulfonating agent, where the linear alkylbenzene is produced by a reaction between an olefin and benzene; and (b) contacting the sulfonation pr...

Summary:Disclosed are processes for preparing linear alkylbenzene sulfonic acids and their corresponding salts comprising: (a) treating a linear alkylbenzene with a sulfonating agent, where the linear alkylbenzene is produced by a reaction between an olefin and benzene; and (b) contacting the sulfonation product of (a) with a mixture of a protic reagent and hydrogen peroxide to result in a sulfonic acid/peroxide mixture. La présente invention concerne des procédés de préparation d'acides sulfoniques d'alkylbenzène linéaires et de leurs sels correspondants. Ces procédés comprennent: (a) le traitement d'un alkylbenzène avec un agent de sulfonation, l'alkylbenzène linéaire étant produit par une réaction entre une oléfine et le benzène, et (b) la mise en contact du produit de sulfonation de (a) avec un mélange d'un réactif protique et de peroxyde d'hydrogène, ce qui donne un mélange d'acide sulfonique et de peroxyde.
