reactor, adding an alcohol feed at about 0.2-10% w/w and oxygen to the second reactor, maintaining a steady- state aldehyde concentration in the reaction mixture, the concentration of residual alcohol being about 0.1-9% w/w by controlling the rates of introduction of effluent and alcohol ...
Oxidation of Alcohols - The oxidation of alcohols is an important reaction in organic chemistry. The oxidation of alcohols to the corresponding carbonyl compounds, say aldehyde or ketone, plays a central role in organic synthesis. Learn about the Lucas t

The oxygen atom of the alcohol group is rich in electrons and attracts the hydrogen ion from the acid. The attraction for the hydrogen ion activates the oxidation reaction that ends in forming an aldehyde or ketone. How do you oxidize an alcohol to a ketone? The secondary alcohol is treated...
Oxidation of the tricyclic diol I with the chromic anhydride-pyridine complex converts the primary alcohol function to the corresponding aldehyde II in 68% yield. The methallyl group of II is hydroxylated and the resulting glycol is clea... Poos, G. I.,Johns, W. F.,Sarett, L. H. - 《...

After acetalization of 40 with p-methoxybenzylidene acetal, the resultant acetal was reduced with DIBALH57 to give the alcohol 41. Oxidation of 41 under Parikh–Doering conditions58 afforded the aldehyde 42. Unfortunately, Brown59 or Roush37 asymmetric crotylation of 42 failed to induce high ...
oxidised to ketones but can then not be oxidised further. Tertiary alcohols can not be oxidised at all. Strong oxidising agents such as acidified Potassium dichromate or weak oxidising agents such as blue Cu 2+ (in Fehlings solution) which are reduced to form orange brown Cu2O can be used...
The addition of an aliphatic alcohol (methanol, ethanol, 2-propanol or tert-butanol) in small amounts with respect to water decreased the overall oxidation rate of aromatic alcohols but enhanced the selectivity for aldehyde formation up to 1.5 times. The reactivity results suggest that: (i) the...
