Hydrolysis processing method for producing an organic compound having a sulfo group, a method of manufacturing a liquid composition and an organic compound having a sulfonyl fluoride group

The present invention provides a small number of steps and with a small amount of waste liquid organic compound having a sulfonyl fluoride group produced efficiently hydrolyzing an organic compound having a sulfo group. This method is an organic compound having a sulfonyl fluoride group in contact with subcritical water at 200 ~ 320 ℃, the sulfonyl fluoride is converted into a method for producing an organic compound having a sulfo group, a sulfo group.
