Benzyl Alcohol to Benzaldehyde : TheeHive

That may be true if you use it to oxidize toluene but for whatever reason there's almost no overoxidation of benzyl alcohol as long as you get your stoichiometry right and have good mixing Another thing: MnO2 is the major product of KMnO4 oxidation and even that can oxidize benzyl alcohol to benzaldehyde So take that into consideration

Green and Direct Synthesis of Benzaldehyde and Benzyl

High yields of valued benzaldehyde and benzyl benzoate are obtained in one pot starting from benzyl alcohol using oxygen as only oxidant under mild conditions (2 bar O2 100 C) along with an ultralow amount (0 02 mol %) of Au nanoparticles heterogenized over a spherical ORMOSIL mesoporous support The process is remarkably selective and the catalyst is stable

Benzyl alcohol — Wikipedia Republished // WIKI 2

Benzyl alcohol is an aromatic alcohol with the formula C 6 H 5 CH 2 OH The benzyl group is often abbreviated Bn (not to be confused with Bz which is used for benzoyl) thus benzyl alcohol is denoted as BnOH Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor It is a useful solvent due to its polarity low toxicity and low vapor pressure
