Patent FR-2004969-A1 (FR)
Title: Alkene sulphonic acids and their salts
IPC: C07C303/06
Filed: 1969-03-28
Abstract: Alkene sulphonic acids and their salts.. F5-. Prepared by reacting a solution of a 2-6C olefin, isobutene, in a chlorinated solvent with a sulphur trioxide complex of an organic phosphorous compound at 20-60 degrees. The maximum ratio SO3/olefin is 1. The phosphorous compound is chosen from esters of phosphorous acids with 1-10C alcohols, and is pref. tributyl phosphate. The SO3 complex is prepared by pouring liquid SO3 into an excess of the compound at -20-+30 degrees pref. +15 degrees. At least one mole of SO3 per mole of phosphorous compound is required. The product of reaction is extracted by water or treated with an alkaline solution to concentrate the methyl-propane sulphonic acid in the aqueous phase. Tributyl phosphate is removed by extraction into hexane and after washing and dehydration recycled; SO2-4 is removed by calcium or barium carbonates or hydroxides. Fractional crystallisatsoin yields the salt, normaly the sodium salt. The process is essentially continuous i.e. tributyl phosphate and solvent are recycled. The products are used as detergents and in copolymerisation of acrylonitrile.
