Title: Method for recovering fluorinated sulfonic acid from spent acid
Inventor: HOMMELTOFT SVEN IVAR
IPC: C07C309/06
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for recovering fluorinated sulfonic acid from a spent acid by a thermal processing. SOLUTION: This method for recovering sulfonic acid from a spent acid is to bring a spent acid to a heat processing at step wise or continuously rising temperatures, taking out at least two fractions during the heat processing and recover fluorinated sulfonic acid from each fraction. It is preferable to keep the temperature low and control retention time in a distiller to avoid decomposition of the acid.
