[Table] According to the method of the present invention, the amine represented by the general formula [] is diazotized by a conventional method, and the diazo solution is converted into water or an organic solvent miscible with water (for example, alcohols such as methanol and ethanol, dimethylformamide, etc.). N-alkylformamides such as N-alkylpyrrolidones such as N-methylpyrrolidone, ketones such as acetone and methyl ethyl ketone) and water. ), adjust the pH of the mixture to facilitate the coupling reaction if necessary, and isolate the resulting monoazo dye to obtain a high yield and high purity monoazo dye. can. The monoazo dye represented by the general formula [ ] obtained by the method of the present invention is made of synthetic or semi-synthetic polymeric substances such as polyester fibers, polyacrylonitrile fibers, polyurethane fibers, triacetate fibers, diacetate fibers, etc. Synthetic fibers can be dyed from yellow to blue with good fastness properties. Next, the present invention will be explained in more detail with reference to examples, but the present invention is not limited to the following examples unless it exceeds the gist thereof. Example 1 Nitrosyl sulfuric acid was prepared by adding 2.0 g of sodium nitrite to 28.8 ml of 98% sulfuric acid and dissolving it by heating to 55°C. This reaction solution was cooled and acetic acid 9.12
g was added, followed by dropwise addition of 40% sulfuric acid at 0-5°C. Furthermore, the following formula Add 3.38 (0.02 mol) g of the compound represented by -
After stirring for 2 hours at 2°C to 0°C, 1.0 g of urea was added to prepare a diazo solution. On the other hand, the following formula 4.5 (0.0125 mol) g of the compound represented by was dissolved in 500 ml of methanol to prepare a coupling liquid. The diazo solution was added to this coupling solution over a period of 30 minutes at 0 to 5°C, and the mixture was further stirred for 5 hours. After separating the precipitated crystals, they were washed with water and dried, and the following formula was obtained. 6.51 g of a monoazo compound represented by was obtained. The maximum absorption wavelength of this monoazo compound (80% by volume)
(in acetone aqueous solution) was 598 nm, and purity analysis by high performance liquid chromatography showed a high purity value. When polyester fibers were dyed at high temperature (130°C) using the dye obtained in this example, a blue dyed fabric was obtained. The dyed fabric obtained had good light fastness. Example 2 A diazo solution was prepared from the amino compound of formula [] in the same manner as in Example 1. On the other hand, the following formula 7.16 g of the compound represented by was dissolved in 500 ml of 3% sulfuric acid to prepare a coupling liquid. Add diazo liquid to this coupling liquid at 0-5℃.
The mixture was added over 30 minutes and stirred for an additional 8 hours. After separating the precipitated crystals, they were washed with water and dried, and the following formula was obtained. 7.19 g of a monoazo compound represented by was obtained. The maximum absorption wavelength of this monoazo compound (80% by volume)
(in acetone aqueous solution) was 613 nm, and purity analysis by high performance liquid chromatography showed a high purity value.
