ABSTRACT:
The invention relates to the synthesis of tertiary mercaptans from isobutylene homopolymers and from hydrogen sulphide by means of heterogeneous catalysis.
In the processs according to the invention, the reaction is carried out at a temperature below 45.degree. C., preferably between 0.degree. and 35.degree. C., in the presence of a catalyst consisting of a dry cation exchange resin.
Excellent yields of tertiary mercaptan are thus obtained, while the formation of undesirable byproducts is virtually avoided.
