摘要：
The invention relates to the use of selected carboxylic acid esters which are liquid under reaction conditions and correspond to general formula (I)X--COOR.sup.1 (I)in which R.sup.1 is an alkyl radical unbranched in the .alpha.-position and X is hydrogen or a group corresponding to general formula (II) ##STR1## in which R.sup.2, R.sup.3 and R.sup.4 represent fluorine and/or chlorine and one of these substituents may also be hydrogen or one or two of these substituents may also be lower alkyl, as reaction medium for the sulfonation and/or sulfatization or organic components with SO.sub.3 to light-colored reaction products.
