Abstract
"Process for obtaining cyclohexanol and cyclohexanone" by oxidation of cyclohexane with oxygen or oxygenated gases at a temperature comprised between 120 and 160º C and high pressure, conveniently in several reaction vessels placed in series, and washing the reaction mixture at least after leaving the last reaction vessel, with water and then with an aqueous solution of hydroxide or alkali carbonate, characterized in that the cyclohexane which has not been transformed and contained in the treated reaction mixture is removed by distillation until the The cyclohexane in the residue is less than 20% by weight, then the residue is treated at elevated temperature with hydroxide or alkali carbonate dissolved in water, the amount of which is between 0.2 and 0.95 equivalent parts, with respect to the esters contained in the residue, to decompose the mixture then, by distillation, in cyclohexanone, cyclohexanol and a residue which contains the alkali.
