Process for hydrolysis of ion exchange membranes

摘要

A process is provided for hydrolysis of fluorinated ion exchange membranes. The membrane is contacted with an aqueous solution containing a hydrocarbon having ether, epoxy or ketone linkages and an alcohol group, preferably 1-methoxy 2-propanol, for a period of time sufficient to perform the hydrolysis of the precursor groups. The membrane is useful in a fuel cell or in an electrolytic cell, particularly a chloralkali cell.
