METHOD OF OBTAINING n-CYMENE HYDROPEROXIDE Russian patent published in 2012 - IPC C07C407/00 C07C409/08 

FIELD: chemistry.

SUBSTANCE: invention relates to obtaining n-cemene hydroperoxide, which can be used for combined production of cresol and acetone. In accordance with invention claimed is method of obtaining n-cymene hydroperoxide by liquid-phase oxidation of n-cymene with air oxygen at atmospheric pressure, temperature of the process 80-110°C, for 1-3 hours, in presence of N-hydroxyphthalimide as catalyst in amount 1-5 wt %, until content of n-cymene hydroperoxyde is 25-28%.

EFFECT: catalyst excludes application of initiator and alkaline additives, which simplifies the process considerably; high rate of n-cymene oxidation is achieved.
