Linear sulfonic acid is an organic compound which is used in the production of a wide variety of detergents and emulsifiers. It is widely used in the production of liquid detergents, as a detergent in the textile, galvanic, leather and paper industries and as a degreaser.


The production of alkylbenzene dates back to the 1950s, when an alkylbenzene was synthesized in Germany and the United States by paraffin monochloration followed by the Friedel-Crafts reaction. Branched α-dodecylene was also obtained by tetramerization of propylene, which also produced alkylbenzenes by reaction with benzene in the presence of aluminum chloride or hydrofluoric acid, making available an economic process for the synthesis of alkylbenzene. Branched alkylbenzene sulphonates, BABS, have been synthesized with these ingredients, which have replaced the soaps in the composition of detergents
