  • Title: Mechanism of O2-accelerated sonolysis of bisphenol A.
    Author: Kitajima M, Hatanaka S, Hayashi S.
    Journal: Ultrasonics; 2006 Dec 22; 44 Suppl 1():e371-3. PubMed ID: 16806361.
    Abstract:
    The effects of dissolved gases on the sonochemical degradation of bisphenol A (BPA) were studied at a frequency of 500 kHz. BPA degradation rate increased in the order O(2)>Ar>air>N(2). The rate constant for oxygen (2.6 h(-1)) was approximately two fold higher than that for argon (1.2 h(-1)). A primary intermediate (2,3-dihydro-2-methylbenzofuran), a typical intermediate of BPA formed during attack by OH radicals, was detected only in the presence of oxygen, revealing that a different reaction path was responsible for the enhancement of decomposition.
