production method | (1) is obtained by reacting p-chloroaniline with benzoyl chloride. First, add P-chlorobenzene to the glass lining reaction pot, add anhydrous zinc chloride below 70 ℃, add benzoyl chloride Dropwise under stirring, and then raise the temperature, keep the temperature at 195-205 ℃ for 2H, it is washed five times with hot water of 90-95 ℃ (benzoic acid and zinc chloride are recovered from the water layer and the washing liquid) at about 100 ℃, sulfuric acid is slowly added, and the temperature is kept at 142 ℃ for 40min. The feed solution was poured into water at 0-5 °c while hot to precipitate a solid. Under stirring, the pH was adjusted to not higher than 1 with liquid alkali and filtered at 20-25 °c. P-chloroaniline was recovered from the filtrate. The filter cake was suspended in water, neutralized to pH = 6, dried by filtration, washed with water until neutral, and dried to obtain a crude product. Then add 6-7 times ethanol, 6% activated carbon, reflux 30min, filter crystallization, drying and get fine. (2) isoxazole is obtained by the synthesis of p-nitrochlorobenzene and cyanobenzyl, followed by ring opening and reduction. |
