The present invention relates to a continuous method for oxidizing
saturated cyclic hydrocarbons by oxygen to obtain a mixture of
hydroperoxides, alcohols and ketones. It relates more particularly to a
method for oxidizing cyclohexane in a column forming a bubble reactor,
for the formation of cyclohexyl hydroperoxide, cyclohexanol and
cyclohexanone. According to the invention, the column may be supplied
with oxygen-enriched air, while meeting the maximum oxygen concentration
requirements in the headspace of the reactor to avoid any risk of
explosion.
