Oxidation of 1-phenylethanol in the presence of cobalt acetylacetonates
Abstract
The oxidation of 1-phenylethanol has been investigated in the presence of Co(acac)2 and Co(acac)3. It is established that in the presence of Co(acac)2 the oxidation is preceded by the formation of a Co(acac)2—ROH complex and the fast oxidation stops abruptly due to the deactivation of the catalyst. The rate constants and the overall activation energy were determined. In the presence of Co(acac)3 the oxidation began after an induction period. It is assumed that the actual catalyst for this process is Co(acac)2. The overall activation energy has been determined.
