Title:
RESIN SOLID ACID AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2015143348
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a resin solid acid for which intermediate-stage production costs can be reduced by the omission of a synthetic resin carbonization step and the direct addition of a sulfo group to a synthetic resin, and to provide a method for producing the resin solid acid.SOLUTION: A resin solid acid is a sulfo-group-modified resin obtained by introducing a sulfo group to an un-carbonized raw material resin. The yield of the sulfo-group-modified resin is 80% or more based on the weight of the un-carbonized raw material resin, the sulfo group content of the sulfo-group-modified resin is 1 mmol/g or more, and the raw material resin is a powdered material, a granular material, or a fibrous material. Also, a producing method for obtaining the sulfo-group-modified resin comprises: a step for adding to the un-carbonized raw material resin a sulfonating agent that is sulfuric acid, fuming sulfuric acid, or chlorosulfonic acid; and a step for heating the raw material resin at a temperature of 200°C or lower.
