| titleOfInvention | Manufacture of acid dyestuffs of the anthraquinone series |
| abstract | Greenish-blue dyes of the anthraquinone series are obtained by treating a 1-amino-4-halogenanthraquinone-2-sulphonic acid or a salt thereof with an amide of an aminocarboxylic acid of the benzene series or a derivative thereof, in which the amide group may be substituted by alkyl, hydroxyalkyl or cyclohexyl groups. According to examples the sodium salt of 1-amino-4-bromoanthraquinone-2-sulphonic acid is condensed with o-, m-, or p-aminobenzamide, 3- and 4-chloro-1-amino-5-benzamide, o-, m-, or p-aminobenzoic cyclohexylamide, m-aminobenzoic dimethylamide, and corresponding 3- and 4-chlor derivatives thereof, p-aminobenzoic methylamide, o-, m-, or p-aminobenzoic ethanolamide; o-, m-, and p-aminobenzoic mono and diethyl amides and chloro substitution products of these are also specified. Specifications 10378/14 and 7861/15, [both in Class 2 (iii), Dyes &c.], are referred to. The amino-carboxylic amides employed are obtained by causing a nitrocarboxylic chloride of the benzene series to condense with an amine or ammonia, followed by reduction of the nitro group. |
