The process involves the cofeeding of an acrylonitrile with an appropriate alcohol or its equivalent and a strong acid to form an acrylamide which is thiolated to form a mercapto-propionamide which is halogenated to afford the desired biocidally active isothiazolones. This invention relates to a novel process for preparing N-substituted 3-mercaptopropionamides, an intermediate in the preparation of isothiazolones.
该过程涉及共投酰腈与适当醇或其等效物和强酸,形成丙烯酰胺,然后硫化形成巯基丙酰胺,再进行卤代反应以制备所需的具有生物杀菌活性的异噻唑酮。这项发明涉及一种制备N-取代3-巯基丙酰胺的新型方法,这是制备异噻唑酮的中间体。
