Abstract

12,162. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. May 22. Carboxydiarylhydrols are obtained by condensing one molecule of a substituted benzaldehyde with one molecule of an aromatic o-oxvcarboxylic acid. According to an example, pdiethylaminobenzaldehyde and s-xylenol-o-carboxylic acid are condensed in sulphuric acid solution; products are also described from the following pairs of substances : -o-chlorbenzaldehyde and s-xylenol-o-carboxylic acid, 2:6-dichlorbenzaldehyde and m-cresotinic acid. 2:6- dichlor-3-oxybenzaldehyde and m-cresotinic acid, 2:6-dichlor-3-methoxybenzaldehyde and sxylenol-ocarboxylic acid, o-sulphobenzaldehyde and m-cresotinic acid or s-xylenol-o-carboxylic acid, 2-chlor-o-sulphobenzaldehyde and s-xylenolo-carboxylic acid, 2:5-disulphobenzadehyde and s-xylenol-o-carboxylic acid, p-diethylaminobenzaldehyde and 2-naphthol-3-carboxylic acid, ochlor-p-dimethylaminobenzaldehyde and mcresotinic acid or s-xylenol-o-carboxylic acid, o-chlor-p-diethylaminobenzaldehyde and m- or p-cresotinic acid, s-xylenol-o-carboxylic acid, or 1-naphthol-2-carboxylic acid; polychlorbenzaldehydes, 3-methyl-2-oxy-4-chlorbenzoic acid, and sulphonic acids of the oxycarboxylic acids are also mentioned as parent materials. Triarylmethane dyes are obtained by condensing the above-described carboxydiarylhydrols with aromatic o-oxycarboxylic acids and oxidizing the leuco bodies so produced; products are described from o-cresotinic acid and the specific hydrols mentioned above; these dye wool blue to violet shades with chrome mordants.
