Title:
３，４－ジクロロ－Ｎ－（２－シアノフェニル）－５－イソチアゾールカルボキサミドの製造方法
Document Type and Number:
Japanese Patent JP7179028
Kind Code:
B2
Abstract:
The present invention relates to a novel process for preparing and isolating 3,4-dichloro-N-(2-cyanophenyl)-5-isothiazolecarboxamide (Isotianil), which can be used as an active compound with microbicidal properties, wherein the amount of waste materials—e.g. solvents and diluents—is significantly reduced and the process meets the requirements of industrial scale production, in particular that it provides the product in high yield, high purity, i.e. minimum amount of by-products and impurities, and can be carried out with tolerable corrosivity in industrial scale metal, in particular stainless steel, vessels or Cr—Ni—Mo alloy pressure filters or centrifuges.
