Method for producing organic compound having sulfo group, method for producing liquid composition, and method for hydrolyzing organic compound having fluorosulfonyl group
View Patent ↗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.
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.
3. 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 fluorinated polymer.
4. A method for producing a liquid composition containing an organic compound having a sulfo group and water, which comprises treating a composition containing an organic compound having a fluorosulfonyl group and water at from 200 to 320° C. under conditions that water becomes subcritical water, to convert the fluorosulfonyl group into a sulfo group to obtain a composition containing an organic compound having a sulfo group and water.
5. The method for producing a liquid composition according to claim 4 , wherein the organic compound having a fluorosulfonyl group is a perfluorocompound.
6. The method for producing a liquid composition according to claim 4 , wherein the organic compound having a fluorosulfonyl group is a fluorinated polymer.
7. A method for hydrolyzing an organic compound having a fluorosulfonyl group, which comprises bringing an organic compound having a fluorosulfonyl group into contact with subcritical water at from 200 to 320° C. to hydrolyze the fluorosulfonyl group.
8. The method for hydrolyzing an organic compound having a fluorosulfonyl group according to claim 7 , wherein the organic compound having a fluorosulfonyl group is a perfluorocompound.
9. The method for hydrolyzing an organic compound having a fluorosulfonyl group according to claim 7 , wherein the organic compound having a fluorosulfonyl group is a fluorinated polymer.
10. The method for hydrolyzing an organic compound having a fluorosulfonyl group according to claim 7 , wherein the fluorosulfonyl group is converted into a sulfo group by hydrolysis.
