procedures for sulphated and / or sulfation organic components with so3 in an organic reaction medium.

摘要

Selected carboxylic acid esters of formula X-COOR1 (I), which are liq. under the prevailing reaction conditions, are used as reaction medium for the sulphonation and/or sulphation of organic cpds. with SO3. In (I), R1 = an unbranched alkyl residue in the alpha-position and X = H or a residue of formula (II) in which R2, R3 and R4 = F and/or Cl or one of R2, R3 and R4 may also be H or one or two of R2, R3 and R4 may also be lower alkyl.
