概要
- 論文の詳細を見る
Photodegradation of BHA exposed to sunlight was studied. As a result, two types of oxidation products were separated in the form of white crystal. IR, MR, NMR and elementary analyses showed their chemical structures to be 2,2'-dihydroxy-5,5'-dimethoxy-3,3'-di-tert-butyl biphenyl and 2', 3-ditert-butyl-2-hydroxy-4', 5-dimethoxy-biphenyl ether. Both substances are dimers with a molecular weight of 358,the former being a diphenyl compound with a melting point of 224,5°and the latter being a diphenyl ether compound with a melting point of 78-79°.
