Abstract

PURPOSE:To obtain the titled compound, used as a coloring material, and useful as a synthetic intermediate for dyes and pigments in high purity and yield, by reacting 1-aminoanthraquinone with an alkyl halide in the presence of an alkali in sulfolane. CONSTITUTION:1-Aminoanthraquinone is reacted with an alkyl halide in the presence of an alkali (a hydroxide, carbonate or bicarbonate of an alkali metal or alkaline earth metal, particularly caustic potash) in sulfolane at 0-150 deg.C, preferably 20-100 deg.C to give the aimed 1-alkylaminoanthraquinone of the formula (R is alkyl which may be substituted). Preferably, the reaction molar ratio between the 1-aminoanthraquinone and the alkyl halide is 1:1-3, and the molar amount of the sulfolane to be used is 2-10 times that of the 1-aminoanthraquinone.

The present inventors have developed a method using 1-aminoanthraquinone as a raw material, for which the technology has already been established as a new non-polluting process.
-As a result of intensive studies on the synthesis method of alkylaminoanthraquinone, we found that 1-aminoanthraquinone was synthesized in sulfolane (tetrahydrothiophene) in the presence of an alkali,
The present invention was completed based on the discovery that selective monoalkylation occurs when reacted with an alkyl halide, and 1-alkylaminoanthraquinone can be obtained with high purity and high yield.
