Abstract

Cyclohexane is oxidised in the liq. phase under press. with O2-contg. gases in the presence of catalysts such as salts of metals with variable valency, esp. Co naphthenate, to a degree of conversion of up to 5 % in more than one reaction stage in a multistage gas injecion tube system, while maintaining a limited oxygen concn. within the liq. phase. - Pref. the oxidn. is carried out in the presence of Co naphthenate in a concn. of 0.2 - 5 ppm, esp. 0.5 - 2 ppm in the reactor and with a max. concn. of oxygen in the liq. phase (in mol/dm3 x 10 power -4).
