The present invention relates to a novel, one-stage method for preparing and isolating 3,4-dichloro-N-(2-cyanophenyl)-5-isothiazolecarboxamide (isotianil), which has microbicidal and plant-fortifying (host defence inducer) properties. In the method according to the invention, the amount of waste from the production process (e.g. solvent) is significantly reduced. The product is provided in high yield and purity (minimal amount of by-products and impurities). Compared to existing preparation methods, the method according to the invention has the advantage of low corrosiveness and high yield and high selectivity.
本发明涉及一种新颖的一步法,用于制备和分离3,4-二
氯-N-(2-
氰基苯基)-5-
异噻唑甲酰胺(异菌灵),该化合物具有杀菌和植物强化(宿主防御诱导剂)特性。根据本发明的方法,生产过程中产生的废物量(例如溶剂)显著减少。所得产品具有高收率和纯度(极少的副产品和杂质)。与现有的制备方法相比,本发明的方法具有低腐蚀性、高收率和高选择性的优点。
