Abstract
Process for the preparation of ethylphenols and acetaldehyde, characterized in that it consists of; reacting a liquid mixture, consisting essentially of diethylbenzene, with a gas containing molecular oxygen, at a temperature comprised between 100 and 180º c, in order to transform in this oxidation step, from 5 to 30% of diethylbenzene in hydroxy peroxide of diethylbenzene, remove the reaction mixture, evaporate the non-transformed diethylbenzene, to obtain a concentrate, containing at least 40% of diethylbenzene hydroperoxide and return to the cycle, to the oxidation stage, diethylbenzene, which has not reacted, mix the diethylbenzene hydroperoxide concentrate with a solvent of the group comprising the aliphatic alcohols and ketones with low molecular weight and mixtures thereof, decomposing this hydroperoxide by intimate contact with a strong acid, used in an amount comprised between 0.05 and 5% of the weight of the the total reaction mixture, and neutralize the resulting mixture, distill the neutralized mixture to recover a fraction of cola, containing ethylphenol and a head fraction, containing acetaldehyde.
