Abstract

293,703. I. G. Farbenindustrie Akt.- Ges. July 7, 1927, [Convention date]. Aldehydes; ketones; alcohols; esters; acids.- Substances with pronounced perfume which are aromatic compounds containing two isopropyl groups, are produced by introducing a keto group into aromatic compounds containing two isopropyl groups by known methods; or by introducing a keto group and simultaneously a second isopropyl group into an aromatic compound which contains onlv one isopropyl group linked to the nucleus. By further changing the keto group introduced or already present, in known manner, different perfumes may be obtained. In the examples di-isopropyl-benzaldehyde is produced by treating di-isopropyl-benzene with carbon monoxide in presence of aluminium chloride and cuprous chloride with or without gaseous hydrochloric acid; or by treating cumol with carbon monoxide in presence of aluminium chloride and cuprous chloride. Di-isopropylacetophenone may be made in a similar manner. Di-isopropylbenzalacetone is produced by alkaline condensation of acetone with isopropyl-benzaldehyde. Di-isopropylbenzoic acid is obtained by oxidizing the corresponding aldehyde, and its esters may be prepared. Di-isopropyl-benzylalcohol is obtained by chemical or catalytic reduction of the aldehyde, and its acetate by acetylation. Di-isopropyl cinnamic aldehyde and its homologues are obtained by condensing diisopropyl benzaldehyde with acetaldehyde and its homologues, and from these the corresponding hydrocinnamic aldehydes are obtained. The Specification as open to inspection under Sect. 91 (3) (a) describes the preparation of diisopropyl benzaldehyde by treating cuminic aldehyde with isopropyl chloride dissolved in carbon bisulphide, in the presence of aluminium choride. This subject-matter does not appear in the Specification as accepted.
