Procedure

After sulphonation the reaction mixture is generally diluted with hexane and where a process that yields sulphonic acids rich in sulphuric acid such as oleum sulphonation is used we prefer that the diluted reaction mixture be allowed to stand for sulphuric acid to settle. Following this from 1% to 30%, preferably 5% to 15% of water by weight based on the weight of the alkylate from which the sulphonic acid is derived is added, the mixture agitated and conveniently is then allowed to stand to allow settlement of the aqueous layer which may then be removed by decantation.
