The nature of alcohol oxidation depends greatly on the molecules reactivity and the nature of the oxidizing reagent. This video walks you through the step by step mechanism for the common alcohol oxidation mechanisms. Chromic Acid, PCC, and KMnO4 Video 6 – Sodium Borohydride (NaBH4) Reduction Yo...

Freshly prepared 1 can oxidize alkylbenzenes such as toluene, ethylbenzene, and cumene at room temperature to give the corresponding ketone and/or alcohol products. Ce–LOEt complexes are efficient promoters of the aerobic oxidation of alkylbenzenes by a radical mechanism. For example, cumene in ...
When sec-phenethyl alcohol was labeled with 18O, 80% of the oxygen was retained in the ketone. Tests for the possible intervention of a free radical intermediate were carried out; the evidence was entirely negative. A mechanism featuring hydride abstraction is proposed, the first time for the ...
SO2 can also consume a large amount of SO32⁻, which will result in a significant reduction of NOx absorption amount. The addition of any antioxidants is considered as an effective way to solve the first problem. Those antioxidants mainly are alcohol, phenols, and organic amines, etc. Wang...
The effects of time and temperature on the oxidation reaction were studied using an internal mixer. The reaction was performed in the presence of traces of hexadecyl alcohol as an accelerator. In certain cases, biphenyl was uscd as a conipatibilizing agent in the molten state. The oxidized ...
