Abstract

In a process for the preparation of an alkali metal or ammonium alkyl aryl sulphonate of low inorganic salt content, the sulphonic acid containing reaction mixture obtained by sulphonating e.g. with oleum and alkyl aryl compound is neutralized with a stoichiometric excess of an aqueous solution of alkali metal hydroxide or ammonium hydroxide having a concentration of between 5 and 15% by weight, the neutralization mixture cooled to below 70 DEG C. and the alkali metal or ammonium sulphate is separated e.g. by gravity or mechanical means from the aqueous layer. The sulphonic acid-containing reaction mixture may be de-acidified before neutralization and the separated sulphonate-containing layer may be neutralized with a slip stream of the sulphonic acid layer obtained in the de-acidification step.
