Studies on the Antioxidants. VI. Photodegradation of Butyl Hydroxyanisole (BHA). (2)

Abstract

Quantitative fluctuation of butyl hydroxyanisole (BHA) after photo-oxidation was studied. Data on the residual amount of the compound and products formed indicated that irradiation of BHA with light results in the formation of oxidative product with exhaustion of BHA per se. Though the amount of BHA decreased in proportion to the duration of irradiation, the amount of oxidates, which was very small, did not show notable changes with time. Of the two oxidation products formed, a higher yield was regularly obtained with diphenyl compound than with diphenyl ether compound. The behavior of benzene and soybean oil, used as a solvent, was similar even in a different milieu.
