    摘要: In the production of .alpha.-sulfofatty acid alkyl ester alkali metal salt pastes by reaction of fatty acid alkyl esters with gaseous SO.sub.3, subsequent after-reaction in liquid phase and neutralization with aqueous alkali metal hydroxide solutions, the crude sulfonation product is fed to an at least two-stage cascade of stirred tanks equipped with heating and cooling systems in which it is subjected with mechanical agitation to a temperature-controlled after-reaction until a degree of sulfonation of at least 90% is reached, after which the aged sulfonation product is further processed in known manner to .alpha.-sulfofatty acid alkyl ester alkali metal salt pastes.
