Abstract

In a process for the production of phenols and carbonyl compounds by the decomposition by means of sulphuric acid of a hydroperoxide of an aromatic hydrocarbon substituted by one or more alkyl groups of which at least one contains a secondary or tertiary carbon atom, the hydroperoxide and the sulphuric acid are brought into contact at elevated temperature in the presence of a quantity of the phenol to be formed in the reaction, said phenol being introduced before the reaction has commenced, the initial reaction mixture being free from the carbonyl compound formed in the fission reaction or containing a proportion of such carbonyl compound less than 10 per cent of the combined weight of said phenol and said carbonyl compound. Hydroperoxides mentioned are those of cumene and its homologues, e.g. of p-cymene, isobutylbenzene, di-isopropylbenzene and ethylbenzene (which yields phenol and acetaldehyde). The hydroperoxide and phenol may be mixed before adding the acid, but preferably the acid and hydroperoxide are added simultaneously to a hot mass of liquid phenol (termed a "foot"). The sulphuric acid may be in such amounts as 1 to 5 per cent by weight in relation to the hydroperoxide and may be used at a concentration of 30 to 75 per cent, which is completely soluble in the "foot". The cumene hydroperoxide may be a crude product resulting from the partial oxidation of cumene from which the greater part of the unconverted hydrocarbon has been removed by distillation and/or steam distillation. Such a product may contain, for example, 5 per cent of cumene and 5 per cent of water, or a higher cumene content for less water. The reaction is preferably carried out at below 65 DEG C. It may be performed continuously, if desired with elimination of the carbonyl compound as it is formed. In examples (1) crude cumene hydroperoxide and 50 per cent sulphuric acid are run into phenol initially heated to 45 DEG C. to give phenol, acetone, and as by-products, methyl-styrolene and acetophenone; (2) a similar process to (1) is effected at reduced pressure with continuous distillation of the acetone produced; (3) p-cymene peroxide and 50 per cent sulphuric acid are run into p-cresol heated at 40 DEG C. Reaction is effected at 45 DEG to 50 DEG C. to give p-cresol and acetone; (4) in a similar process to (3) isobutylbenzene hydroperoxide is decomposed to give phenol and methylethyl ketone.
