Method for producing sulfonic acid group-containing carbonaceous material, solid acid catalyst, method for producing alkylation reaction product, and method for producing olefin polymer

摘要

The method for producing a sulfonic acid group-containing carbonaceous material of the present invention comprises the step of carbonizing and sulfonating a polymer having a structural unit derived from resorcinol by heating in an inert gas atmosphere to obtain a sulfonic acid group-containing carbonaceous material. A catalyst comprising the resulting sulfonic acid group-containing carbonaceous material is useful for producing a target substance with high efficiency in various reactions in hydrophobic media such as alkylation reaction and polymerization reaction of olefins.
