Abstract

Leuco-sulphuric esters of 1 : 11-di-anthraquinonylamides of dicarboxylic acids are made by treating the vat dye in presence of a metal, or treating a metal salt of a leuco-derivative of a vat dye, with a sulphating agent such as sulphur trioxide in presence of an amide derived from a secondary amine. Amides specified are dimethylformamide, diethylformamide, dimethylacetamide, tetramethylurea, N : N - diethyl - p - toluenesulphonamide. Acetone and acetonitrile are specified diluents. In examples: (1) terephthal-4 : 41-dibenzoylamino - 1 : 11 - dianthraquinonylamide is reacted with zinc dust and sodium-b -naphthalene sulphonate in dimethylformamide, and then with the addition product of dimethylformamide and methyl chlorsulphonate or sulphur trioxide; (2) terephthal-5 : 51-dibenzoylamino - 1 : 11 - dianthraquinonylamide is reacted with zinc dust, tetraethylammonium iodide and dimethylformamide, and then with dimethylformamide and methyl chlorsulphonate; (3) terephthal-1 : 11-dianthraquinonylamide is reacted with N-formomorpholide, acetone, zinc, and methyltriethylammonium chloride and then with methyl chlorsulphonate and more N-formomorpholide; (4) oxal-5 : 51-dibenzoylamino - 1 : 11 - dianthraquinonylamide is reacted with zinc, sodium b -naphthalene sulphonate, methyltriethylammonium chloride, and dimethylformamide, and then with dimethylformamide and sulphur trioxide. Specifications 274,156, [Class 2 (iii)], 476,255, 610,117, 633,481 and 633,513.
