Method of purification of dihydric phenols

Method of purification of dihydric phenols

A process comprising the steps of dissolving a dihydric phenol in a solvent to form a solution A; contacting the solution A with a zeolite; filtering the zeolite to form a solution B; adding an anti-solvent to the solution B to form a solution C; and distilling the solution C; wherein the dihydric p...
