Abstract

Readily soluble basic dyestuffs are prepared by treating a basic dyestuff or a salt thereof with phosphoric acid or by oxidizing the corresponding leuco base in the presence of phosphoric acid. An alkali phosphate may also be present. The treatment of a salt of tetra-methyl-p-tolyltriaminodiphenyl-a -naphthyl carbinol anhydride (Colour Index 731) or the corresponding base is excluded. In examples, (1) Victoria blue R (Schültz "Farbstofftabellen" 7th Edition No. 821) or similar dyestuffs such as No. 822, 823, 793 (Schültz) is boiled with phosphoric acid and sodium phosphate. The dyestuff is salted out of the cooled and filtered solution by means of an alkali phosphate. (2) The dyestuff from tetramethyl-diaminodiphenylketone and a -b -dinaphthylamine is boiled with phosphoric acid and salted out. (3) The dyestuff from benzaldehyde and n-butyloxyethylaniline (Specification 374,865) is boiled with phosphoric acid and salted out with sodium phosphate. (4) The leuco base of the dyestuff obtained from formaldehyde and 1-n-butyloxyethylamino-3-methylbenzene (Specification 374,865) is oxidized with lead peroxide in the presence of phosphoric acid. (5) The leuco base of the dyestuff obtained from formaldehyde and 1-n-butyloxyethyl-amino-3-chlorobenzene is oxidized with lead peroxide in the presence of sulphuric acid and the solid precipitate is washed with water and treated with phosphoric acid and sodium phosphate. The dyestuff is salted out of the filtered solution. (6) The isorosinduline from phenyl-b -naphthylamine and p-nitrosoethyl-benzylaniline is boiled with phosphoric acid and salted out. (7) The naphthophenosafranine obtained from the isorosinduline of example (6) by oxidizing it together with 4-diethylamine-1-aminobenzene is treated as in example (6). (8) Methylene blue is treated with phosphoric acid in the presence of sodium phosphate.
