Photoinduced Decomposition of Peracetic Acid in Isopropylbenzene

Article abstract of DOI:10.1246/bcsj.53.2419

Irradiation of peracetic acid in isopropylbenzene with 254 nm and over 290 nm lights gave as aromatic products mainly t-butylbenzene, 2-phenyl-2-propanol, and 2,3-dimethyl-2,3-diphenylbutane.The yield of t-butylbenzene was higher in 254 nm photolysis than that with >290 nm, while the yield of hydroxylated aromatics, i. e., 2-phenyl-2-propanol, was much higher with >290 nm than that with 254 nm.The distribution of products was little affected by the intensity of light.These results are discussed by a mechanism involving radicals of different reactivity derived from peracetic acid decomposition.
