咪唑是用途比较广泛的杂环化合物,主要的工业合成路线有两条,一是由乙二醛、甲醛与硫酸铵作用得到产品;二是以邻苯二胺为原料,与甲酸环合得到苯并咪唑,再经过双氧水反应开环,最后脱羧得到产品。目前我国仅有小规模的生产装置,由于下游产品开发不畅,用量非常少。在农药工业中咪唑用于合成杀菌剂咪鲜胺、抑霉唑、氟菌唑、稻瘟酯等。咪唑的 Imidazole is a widely used heterocyclic compounds, the main industrial synthetic route has two, one by glyoxal, formaldehyde and ammonium sulfate to get the product; the second is o-phenylenediamine as raw material, and formic acid cyclization to benzene And imidazole, and then hydrogen peroxide reaction ring, the final decarboxylation products. At present, there is only a small-scale production plant in our country. Due to the sluggish development of downstream products, the dosage is very small. Imidazole in the pesticide industry for the synthesis of fungicide prochloraz, imazalil, triflumizole, rice blast and so on. Imidazole
