PROCESS FOR THE PRODUCTION OF MOBILE PASTES OF WASHING-ACTIVE .alpha.-SULFOFATTY ACID ESTER SALTS OF HIGH SOLIDS CONTENT |
| abstract |
ABSTRACT OF THE DISCLOSURE In the production of washing-active .alpha. -sulfofatty acid esters by sulfonation of fatty acid alkyl esters with SO3 in molar ratios of up to 1:2 and more espe-cially of from 1:1.2 to 1:1.8 and subsequent working-up of the crude sulfonic acid in aqueous medium with salt formation, aqueous pastes which are mobile, more especially pumpable, at moderately elevated tem-peratures are obtained by subjecting the crude sulfo-nate before the treatment with the aqueous medium to a post-reaction with at least about 0.5 mole equivalent, based on the SO3 which is not used for the .alpha.-sulfonation, of monohydric alcohols and/or alkoxyla-tion products thereof at temperatures above 70°C and adjusting the solids contents of the .alpha.-sulfofatty acid ester salts to more than 35% by weight in the sub-sequent aqueous working-up step. |
