Abstract

332,940. Imray, 0. Y., (I. G. Farbenindustrie Akt.-Ges.). March 28, 1929. Dioxyquinolines of the general formula: in which R = a naphthalene residue or a diphenyl radical or a residue of the benzene series which contains a substituent increasing generally the affinity of aromatic compounds to the vegetable fibre (namely an azo- or a psuedoazimino group), n being 1 when R = a naphthalene residue or an aromatic residue containing the aforesaid substituents and 2 when R = a diephenyl radical are made from a. suitable amine and malonic ester. In examples, 2 : 4 : 2<1> : 4<1>-tetraoxy-6 : 6<1>-diquinol<y>l is made from benzidine, 5 : 6-, 6 : 7- and 7 : 8- benzo-2 : 4-dioxyquinolines from 2-naphthylamine, 2-amino-3-naphthoic acid ethyl ester and 1-naphthylamine respectively, 2 : 4-dioxy-6- quinolyl-2'-pseudoaziminobenzene from 1-(4<1>- amiuo-3<1>-carbethoxyphenyl) - 2 : 3-phenotriazole and 2 : 4-dioxyquinoline-6 : 1<1>-azo-2<1>-chloroben - zene from 4 - amino - 2<1> - chlorazobenzene-3-carboxylic acid. 1 - (4<1> Amino-3-carbethoxyphenyl 2 : 3-phenotriazole is made by coupling diazotized o-nitraniline with anthranilic acid, reducing for the purpose of preparing the triazole group and esterifying the carboxy group.
