4-aminotoluene

According to the results of studying of kinetic relationships and mechanism of the process of catalytic oxidation of 4-aminotoluene with ozone in the liquid phase, the basis of the technology of 4-aminobenzyl alcohol and 4-aminobenzaldehyde have been developed. It has been shown that under the ozonation conditions in the solution of acetic anhydride in the presence of sulfuric acid, manganese(II) acetate or its mixture with potassium bromide it is possible to stop oxidation at the stage of forming 4-aminobenzyl alcohol or aldehyde.

The kinetic regularities and mechanisms of oxidation reactions of 4-aminotoluene and its acylation derivatives by the gases that contain ozone in the glacial acetic acid have been studied. The process of liquid-phase catalytic oxidation of 4-acetaminotoluene by ozone in the presence of transition metal salts and their mixtures with potassium bromide to the corresponding acetaminobenzoic acid has been investigated.
