Abstract: 514,450. Dyes : intermediates. GROVES, W. W. (I.G. Farbenindustrie Akt.-Ges.). May 6, 1938, No. 13567. [Class 2 (iii)] Triarylmethane dyestuffs are obtained by condensing one molecular proportion of 3- hydroxy - 4 - carboxybenzaldehyde with two molecular proportions of a secondary or tertiary aromatic amine or with two molecular proportions of an aromatic o-hydroxy carboxylic acid, sulphonating the resulting leuco compound if a sulpho group is not already present, and oxidizing the product to the dyestuff. The latter may be converted in substance or on the fibre into a complex metal compound. In examples : (1) 3-hydroxy-4- carboxybenzaldehyde is condensed with diethylaniline, n-butylethyl-m-toluidine, n-butylo-toluidine and o-cresotinic acid, the leuco compound sulphonated and the dyestuff produced by oxidation, e.g. by means of sodium nitrite ; (2) 3-hydroxy-4-carboxybenzaldehyde is condensed with N-ethyl- N-phenylaminoethane-w-sulphonic acid or N-ethyl-N-phenylaminobenzyl-3-sulphonic acid; (3) 3-hydroxy- 4-carboxybenzaldehyde is condensed with mdiethylaminophenol and the resulting leuco compound sulphonated ; a pyrone compound is obtained by heating after adjustment of the sulphuric acid concentration and the dyestuff produced by oxidation with ferric chloride. Specification 472,407 is referred to. 3 - Hydroxy 4 - carboxybenzaldehyde may be prepared by reducing 4-nitro-2-hydroxybenzoic acid ethyl ester, converting the resulting amino compound into 4-cyano-2-hydroxybenzoic acid ethyl ester and hydrolizing the iminochloride produced by reaction of the cyano compound with stannous chloride and hydrochloric acid.
