Abstract

Procedure for the preparation of sulfur-containing alkylidene bisphenols of the general formula ** (See formula) ** in which R1 means an alkyl group with 1 to 18, carbon atoms, which is unbranched in the alpha position, R2 means an alkyl group with 1 to 8 carbon atoms, linear or branched, or a hydrogen atom, R3 and R5 independently of each other, mean a hydrogen atom or an alkyl group with 1 to 6 carbon atoms and R4 means a linear or branched alkyl group with 1 to 20 carbon atoms, in which the carbon chain can be interrupted by sulfur atoms, characterized by reacting a phenol of formula II in a known manner ** (See formula) ** in which R1 and R2 have the same meaning as before, with a thioaldehyde of formula III ** (See formula) ** in which R3, R4 and r5 have the same meaning as before, in the presence of an acid catalyst.
