Abstract
Process for sulfonating fatty acids and their derivatives, especially fatty acid esters, which do not contain other sulphonatable or sulfatable groups, apart from the carbon atom of alpha constant, by reacting them with excess gas doses, not adducted with anhydride sulfuric acid, characterized in that the sulfuric anhydride necessary for the sulfonation is first dissolved in the sulfonation starting materials, at temperatures where sulfonation is practically not yet carried out or very slowly, then the temperature is gradually increased to a value, in which the sulfonation is carried out at a rate that is technically useful, but can not be used for total sulfonation and then the total reaction is terminated at temperatures above 70º C after at least half of the sulfonation has been sulfonated. starting material at lower temperatures.
