Abstract
PURPOSE: To prepare adipic acid directly, economically and in high yield, by the signale stage oxidation of cylcohexane dissolved in a halogenated hydrocarbon such as carbon tetrachloride, with an ozone-containing gas, while heating the solution.
CONSTITUTION: Cyclohexane is dissolved in a halogenated hydrocarbon such as carbon tetrachloride, heated to 40W65°C, and oxidized with an ozone-containing gas in single stage, to obtain adipic acid. The ozone-containing gas is ozonized oxygen or air which may contain other inert gas. The concentration of ozone is pref. 1W8 wt%. The volume ratio of the cyclohexane to the halogenated hydrocarbon is pref. 5W50%.
EFFECT: Easy control of the reaction, separation of the reaction products, etc
