| Uses | Used as a cationic dye intermediate dye intermediate. It is used to manufacture cationic brilliant blue RL and cationic yellow 2RL; it is used to prepare 6-methoxy-3-methylbenzothiazole hydrazone, and then to produce cationic yellow GL, etc. 2-amino-6-methoxybenzothiazole is a kind of intermediate used to prepare new Schiff base and 4-thiazolidinone compounds. It is also used in the synthesis of 2-cyano-6-methoxybenzothiazole. |
| Production method | First, p-aminoanisole hydrochloride and sodium thiocyanate are reacted to obtain p-methoxyphenyl thiourea, and then closed-loop with sulfur chloride. The process is as follows:(1) Add water in a glass-lined pot, heat to 60°C, slowly add p-aminoanisole under stirring, and stir at 60-65°C for 30min to completely dissolve it. Congo red test paper with 30% industrial hydrochloric acid to adjust the acidity of the solution is slightly blue, maintained for 10min, added sodium thiocyanate, heated, slowly heated to 105 ℃, and refluxed at about 105 ℃ for 24h. Then cold to 25 ℃ and filter. The filter cake is washed and dried with water to obtain p-methoxyphenylthiourea. (2) Inhale anhydrous chloroform into a dry glass-lined pot, and add dry p-methoxyphenylthiourea under stirring. Heat to 60-62 ℃, and evaporate part of the chloroform and water in the raw materials. Then cool to 25°C and gradually add sulfur chloride. After adding, stir at 30 ℃ for 1h, raise the temperature to 43-45 ℃ for 4h. Hydrogen chloride gas is produced in the reaction, which is absorbed by the absorption system. The reflux reaction was carried out at 62-64 ℃ for 10h. Then cool to below 60°C, press the material into an acidic distillation pot filled with chimney ash (substitute activated carbon) and water, and recover chloroform by direct steam distillation until the temperature is 95°C and maintained for 15min. After chloroform is recovered, distillation is stopped, cold to 90 ℃, water is added to adjust the volume, ice is added to cool to 45 ℃, 30% liquid alkali is added in trickle, pH value is adjusted to 4-5, and stirring is carried out for 15min. Suction filtration, the filtrate is heated to 60 ℃, and phenolphthalein is reddish for alkali analysis with 30% liquid alkali. Suction filtration, the resulting filter cake is the finished product. Melting point 160-163 ℃ yield 85%. |
