Abstract: Improved process for the production of alkyl sulphonic acid hydroxy alkyl amides by reacting alkyl sulphonic acid chlorides and hydroxy alkyl amines in the presence of acid binding agents wherein aqueous alkali hydroxide solution is used as acid-binding agent, the three components are applied in a substantially stoichiometric ratio, and the reaction is carried out by adding the alkyl sulphonic acid chloride to the hydroxy alkyl amine and adding to the mixture thus obtained the aqueous alkali hydroxide solutions at such a rate that the pH-value of the reaction mixture does not exceed pH 10.
