1-Phenyl-3-hydroxy-1,2,4-triazole Use and Manufacturing
The preparation method is to obtain benzoconazole by reacting 1-phenyl semicarbazide with formic acid. Add 186kg 1-phenylsemicarbazide, 113kg formic acid, 20kg catalyst, 30L water into a 1000L reactor, stir well, heat up to 100℃, reflux for 6h, then add 400L water, cool to 20℃, filter, filter cake 2 After washing with %NaHCO3 and water to neutrality and drying, light yellow crystals are obtained, which is benzoconazole. Phenylhydrazine, urea and formic acid can also be used as raw materials to obtain benzoconazole through condensation and cyclization reactions.
Used as intermediate for pesticide triazophos
