Abstract
Dyes are made by reacting anthraquinones or anthrapyrimidines having at least one primary amino group but no carboxylic or esterifiable hydroxy group with a phosphorus halide and treating the resulting compounds with aqueous alkaline agents. Amino compounds specified are 1-aminoanthraquinones, 1.4 - diaminoanthraquinones, 1.4.5.8 - tetraminoanthraquinones, 1 - amino - 4 - anilidoanthraquinones, 1 - amino - 4 - (p - aminophenyl)-aminoanthraquinones, aminoanthrapyrimidines, 1.4 - diamino - 2 - methoxyanthraquinone and 1.4 - diaminoanthraquinone - 2 - carboxylic acid amide. Phosphorus halides specified are phosphorus trichloride, pentachloride, oxychloride and the corresponding bromine and iodine compounds. Acid-binding agents which may be used are ammonia and organic bases such as pyridine, quinoline or dimethylaniline, which may also serve as solvents. The intermediate compounds, which contain halogen, may be converted to salts of phosphamic acids free from halogen by the use of aqueous alkaline agents such as caustic alkalies, or alkali carbonates. The products are soluble in water and dye acetate artificial silk, wool, silk, and viscose artificial silk fast shades. In examples: (1) 1.4 - diamino - 2 p - methoxyanthraquinone is reacted with phosphorus oxychloride, followed by treatment with sodium carbonate solution to give the sodium salt of the phosphamic acid; the free acid may be reconverted to the anthraquinone by heating with mineral acid and dyes acetate artificial silk, wool, or viscose artificial silk bluish-red shades; 1.4-diaminoanthraquinone (violet shades) or 1-amino-4-(p-aminophenyl)-aminoanthraquinone (blue shades) may also be used; (2) 1-amino-4-p-anisididoanthraquinone is reacted with phosphorus oxychloride, followed by treatment with caustic soda and sodium carbonate (blue shades); (3) phosphorus oxychloride is reacted with 1.4.5.8-tetraminoanthraquinone in pyridine, followed by treatment with caustic soda (blue shades on acetate artificial silk, wool, or silk); (4) phosphorus oxychloride is reacted with 4-amino-1.9-anthrapyrimidine in pyridine, followed by treatment with caustic soda (greenish-yellow shades on acetate artificial silk, wool or silk); (5) 1-aminoanthraquinone is reacted with phosphorus pentachloride in nitrobenzene, followed by treatment with caustic soda (yellow-red shades on acetate artificial silk).
