PROCESS FOR THE SULFONATION AND/OR SULFATATION OF ORGANIC COMPOUNDS WITH S03 IN AN ORGANIC REACTION MEDIUM

摘要

Use of selected carboxylic esters, which are liquid under application conditions, of the formula I… X-COOR<1>… in which R<1> denotes an alkyl radical which is unbranched in the alpha- position and X denotes hydrogen or a radical of the formula II …… in which R<2>, R<3> and R<4> 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.
