Process for the purification of dihydric phenols

Process for the 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 an adsorbent material selected from the group consisting of metal oxides, modified metal oxides, activated carbons, and clays, filtering the adsorbent material to form a s...

description A process comprising the steps of dissolving a dihydric phenol in a solvent to form a solution A, contacting the solution A with an adsorbent material selected from the group consisting of metal oxides, modified metal oxides, activated carbons, and clays, filtering the adsorbent material 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 phenol is represented by Formula (I): wherein R is a hydrogen atom or an aliphatic functionality having 1 to 6 carbon atoms and n is an integer having a value of 1 to 4.
