Abstract

289,564. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). Feb. 1, 1927. Triarylmethane dyestuffs are produced by joint oxidation in alkaline solution of a p-methylated aromatic oxycompound such as p-oxydiarylmethane or the corresponding hydrol and an oxyaromatic compound. In an example methylenedio-cresotinic acid and 2-oxynaphthalene-3 : 6-disulphonic acid are oxidized by means of air in the presence of an oxygen carrier such as copper sulphate. The resulting dyestuff dyes wool with after chroming a reddish-blue shade. Instead of methylenedi-o-cresotinic acid other p-oxydiarylmethanes may be used, such as methylenedi-ocresol, methylenedisalicylic acid, p-monooxydiphenyl methane, 4<1>-diethylamino-3-methyl-4-oxy- 5-carboxydiphenylmethane or 4<1>-oxy-3<1>-carboxynaphthyl - 3 - methyl - 4 - oxy-5-carboxyphenylmethane or hydrols thereof. Instead of 2-naphthol : 6-disulphonic acid other sulphonic acids and also carboxylic acids of 2-naphthol may be used. Phenols, alpha- and #-naphthol, polyoxynaphthols and polyoxyphenols may be used. According to a further example, p-cresotinic acid and ocresotinic acid are oxidized jointly whereby a dyestuff dyeing wool with after-chroming a reddish violet shade is obtained. p-Cresol or its derivatives may replace the p-cresotinic acid and instead of o-cresotinic acid, phenol, cresols, or their derivatives, oxyaromatic acids or mixtures thereof, for example a mixture of o-cresotinic acid and 2-oxy-3-naphthoic acid may be used. 4<1> - Oxy - 3<1> - carboxynaphthyl-3-methyl-4-oxy- 5-carboxyphenylmethane is obtained by condensation of o-cresotinic acid, alpha-oxynaphthoic acid and formaldehyde.
