摘要：
In the production of highly concentrated pastes of .alpha.-sulfofatty acid alkyl ester alkali metal salts by reaction of fatty acid alkyl esters with gaseous SO.sub.3, subsequent after-reaction in liquid phase and neutralization with aqueous alkali hydroxide solutions, the sulfonation product and aqueous alkali metal hydroxide solution are introduced during neutralization into an aqueous phase initially containing at least 55% by weight washing-active substance at a pH value in the range from 2 to 8 and washing-active substance contents of 60 to 70% by weight are established.
