CATALYSIS OF AUTOXIDATION OF 2,6-DI-TERT-BUTYLPHENOL IN WATER BY METALLOPHTHALOCYANINE TETRASULFONATES BOUND TO POLYELECTROLYTE SUPPORTS

2,6-and 2,10-Ionenes and soluble poly(vinylbenzyl)trimethylammonium ch loride polyelectrolytes were synthesized and used as catalyst supports for cobalt-, iron- and copper-phthalocyanine tetrasulfonates on the a utoxidation of 2,6-di-tert-butylphenol in water by molecular oxygen. P olyelectrolyte supported cobalt-phthalocyanine tetrasulfonate showed t he highest activity in comparison with the supported analogous of iron - and copper-phthalocyanine tetrasulfonates. The supported metallophth alocyanine tetrasulfonates had better catalytic activities than the un supported analogous for the reaction. The reaction yielded 3,3',5,5'-t etra-tert-butyl-4,4'-diphenoquinone as the only oxidation product of 2 ,6-di-tert-butylphenol. The extent of the reaction was affected by tim e, temperature, pH, the types and concentrations of supports and metal lophthalocyanine tetrasulfonates.
