Phenol slowly oxidizes on exposure to air and turns pink in color. At first, quinone ( p -benzoquinone) is formed which again reacts with phenol to form a polymerized product phenoquinone which is red in color. There has been research on the oxidation of phenol like wet-air oxidation and catalytic oxidation but those are out of scope.
