METHOD OF PREPARING CYCLOHEXYLHYDROPEROXIDE

摘要

FIELD: chemical industry. SUBSTANCE: method comprises preparing cyclohexylhydroperoxide by conversion of cyclohexane into mixture consisting mainly of 0.5-8 wt % cyclohexylhydroperoxide and 0.1-4 wt % cyclohexanol and cyclohexanone in cyclohexane using oxygen-containing gas at temperature from 130 to 200 C and pressure from 4 to 50 bar for time period from 0.05 to 14 h without catalyst, and the mixture resulting from reaction is optionally subjected to partial expansion. At the beginning of oxidation process, cyclohexane contains 0.1 to 3 wt % oxide products with linear or cyclic chains having from 1 to 6 carbon atoms. The method makes it possible to simplify process and to decrease the number of by-products. EFFECT: higher efficiency. 14 clt
