PRODUCTION PROCESS FOR PREPARING CYCLOHEXANOL AND CYCLOHEXANONE BY CYCLOHEXANE OXIDATION

摘要

the present invention is cyclohexane to prepare an oxidizing cyclohexanol and relates to a cyclohexanone production process, first, dioxygen (dioxygen) cyclohexane (cyclohexane) to non-catalytic oxidation and cyclohexylamine using the the oxidation produces a mixture of hydrogen peroxide (cyclohexyl hydrogen peroxide) as the main product. Next cyclohexyl hydro gen peroxide to proceed the decomposition of the obtained material is cyclohexanol and cyclohexanone and cyclohexanol to produce a non back through the rectification process and cyclohexanone. Apply butyl chromic acid (Tert butyl chromate) homogeneous catalytic cracking process a three step process that combines the decomposition of sodium hydroxide basic aqueous solution, the heterogeneous catalyst cracking process -cyclohexyl hydrogen peroxide decomposition, and tertiary. Step 1 tert-advances the homogeneous catalyst as a catalyst for decomposing chromic acid butyl. Step 2 proceeds in the heterogeneous catalytic decomposition of aqueous hydrogen peroxide solution of a low basic conditions. Step 3 proceeds the decomposition of hydrogen peroxide in basic aqueous solution, the heterogeneous catalyst and basic conditions. Its production process is relatively high total recovery is a long piece continuous production cycle then lower the consumption and production costs. ;
