SULFONATION AND/OR SULFATATION BY SO3 OF ORGANIC COMPONENT IN ORGANIC REACTION MEDIUM

摘要

Use of selected carboxylic esters, which are liquid under application conditions, of the formula I… X-COOR1… in which R1 denotes an alkyl radical which is unbranched in the alpha- position and X denotes hydrogen or a radical of the formula II …IMAGE… in which R2, R3 and R4 represent fluorine and/or chlorine and one of these radicals can also denote hydrogen or one or two of these radicals can also denote lower alkyl, as reaction medium for the sulphonation and/or sulphation of organic components using SO3 to give light-coloured reaction products.
