Reaction of Butyl Hydroxy Anisol with Sodium Nitrite or Potassium Nitrate by Irradiation of Ultra Violet Ray

Abstract

Reaction of butyl hydroxy anisol (BHA) with sodium nitrite or potassium nitrate by irradiation of ultra violet ray were studied. BRA and sodium nitrite or potassium nitrate in ethanol-water (4:1) solution were irradiated by ultra violet ray for 24hr at room temperature. As the results, 4 species of reaction products were identified, and these structure were determined to be 1, 4-dimethoxy-2-nitrobenzene, 1-hydroxy-2-tert-butyl-4-methoxy-6-nitrobenzene, 1, 4-dimethoxy-2-tert-butyl-6-nitrobenzene, 1, 4-dihydroxy-2-tert-butyl-6-nitrobenzene.
At the same time, the degradation products of BHA by ultra violet ray irradiation was studied, as a results, 7 species of degradation products were identified, and these structure determined to be 2-tert-butyl-quinone, 2-tert-butyl-hydroquinone, 2-tert-butyl-1, 4-dimethoxy-benzene, 2′, 3-di-tert-butyl-2-hydroxy-4′, 5-dimethoxy-biphenil ether, 3, 3′-di-tert-butyl-2, 2′-dihydroxy-5, 5′-dimethoxy biphenyl, 3, 3′-di-tert-butyl-2′-hydroxy-2, 5, 5′-trimethoxy biphenyl and 3, 3′-di-tert-butyl-2, 2′, 5, 5′-tetramethoxy biphenyl.
