ABSTRACT:
Organosilicon compounds bearing carboxylic acid groups are easily and economically replaced in high yield by oxidation of a carbinol-functional organosilicon compound with an oxidizer in the presence of a moderator at a pH≧3. Carboxyl-functional organopolysiloxanes highly useful as textile softeners may be obtained by this method.
