Abstract
Official abstract text for this publication.
To provide a method for producing an organic compound having a sulfo group by efficiently hydrolyzing an organic compound having a fluorosulfonyl group with a small number of steps with a small quantity of waste liquid. A method for producing an organic compound having a sulfo group, which comprises bringing an organic compound having a fluorosulfonyl group into contact with subcritical water at from 200 to 320° C. to convert the fluorosulfonyl group into a sulfo group.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing an organic compound having a sulfo group, which comprises bringing an organic compound having a fluorosulfonyl group into contact with subcritical water at from 200 to 320° C. to convert the fluorosulfonyl group into a sulfo group. 2. The method for producing an organic compound having a sulfo group according to claim 1 , wherein the organic compound having a fluorosulfonyl group is a perfluorocompound.…
