Abstract

A process for selectively oxidizing alkyl cyclohexane by air under the catalysis of mu-oxygen bimetal porphyrin, single-metal porphyrin, or their solid carried substance to become alkyl cyclohexanol and alkyl cyclohexanone is disclosed. Said alkyl cyclohexane may be methyl cyclohexane, ethyl cyclohexane, isopropyl cyclohexane, etc. Its advantages are low cost, high catalytic performance, low reaction temp (less than 200 deg.C) and high transform rate.

Description

Technical field:

[0001] The present invention relates to the method for catalytic air oxidation of alkyl cyclohexane to alkyl cyclohexanol and alkyl cyclohexanone Background technique

[0002] Alkyl cyclohexanol and alkyl cyclohexanone are widely used as important intermediates of medicine, pesticide and fine chemical industry because of their better fat solubility than cyclohexanol and cyclohexanone. At present, industrially, alkylcyclohexanols are mainly prepared by hydrogenation of corresponding alkylphenols, while alkylcyclohexanones are produced by nucleophilic substitution of cyclohexanone and halogenated hydrocarbons or by cyclohexenone and alkyl copper lithium The reagents are prepared by nucleophilic addition. WO0214255 discloses a method for preparing methylcyclohexanol by hydrogenating methylphenol, and CH595309 discloses a method for preparing methylcyclohexanone by directly hydrogenating methylphenol. These methods for preparing alkylcyclohexanol and alkylcycl...
