Usage: chemical technology, purification and isolation of cyclohexanone and cyclohexanol from cyclohexane oxidation products. SUMMARY OF THE INVENTION: The organic oxide layer is neutralized by treatment with aqueous solutions of sodium hydroxide and sodium carbonate in two successive mixers at a temperature of 140-150 ° C, with further separation of the desired products by separation and distillation. A mixture of solutions containing 30-66 mol% of an alkaline reagent in the form of sodium carbonate and 10-20 mol% in the form of sodium hydroxide of the total amount of alkaline reagent necessary to neutralize the acid components in the rxidate is fed to the first mixer. In a second mixer, the product is treated with a sodium hydroxide solution, based on the total amount of alkaline reagent remaining up to 100%. The yield of products is increased, the consumption of sodium hydroxide, 1 sludge is reduced. 1 tab. AND |
