Synthesis method of solvent red 169

The invention belongs to the technical field of dyes, and particularly relates to a solvent red 169 synthesis method, which comprises: carrying out a reaction on bromobenzene and isopropylamine underan alkaline condition by using water as a solvent and cuprous chloride as a catalyst to obtain an intermediate N-isopropylaniline; reacting N-isopropylaniline and phthalic anhydride under the action of sulfuric acid and urotropine to obtain 1-isopropylamino anthraquinone. According to the synthesis method of the solvent red 169 provided by the invention, phthalic anhydride is used as a raw material to directly participate in dye synthesis, so that the synthesis process of anthraquinone, nitroanthraquinone and 1-chloroanthraquinone in the traditional process is omitted, the process route is greatly shortened, the discharge of wastes is greatly reduced, and the production cost is reduced.

Solid-liquid phase transfer catalytic reaction of 1-aminoanthraquinone with alkyl halides: A case of N-alkylation

N-Alkylation of 1-aminoanthraquinone I has been carried out under mild condition of solid-liquid phase transfer catalysis using tetrabutyl ammonium bromide and dibenzo-(18)-crown-6 at room temperature in better yield.

Process for the preparation of 1-alkylamino-anthraquinones

Process for the preparation of 1-alkylamino-anthraquinones which comprises reacting 1-nitroanthraquinone with a monoalkylamine in the presence of an ether, a hydrocarbon or a mixture of an ether and a hydrocarbon. The 1-alkylamino-anthraquinones which are obtained can be employed directly as dyestuffs or used, without further purification, for the production of dyestuffs. Process of the invention results in the procurement of 1-alkylamine-anthraquinones of high purity and in high yield and avoids the formation of undesired by-products.
