Title (EN) METHOD FOR PREPARING HYDRONIDONE
(FR) PROCÉDÉ DE PRÉPARATION DE HYDRONIDONE
(ZH) 一种羟尼酮的制备方法
Abstract: front page image
(EN)Provided is a method for preparing hydronidone. The method features easy operations, mild reaction conditions, a short reaction time and a high yield; the method is safer and suitable for large scale production. The method uses ammonium hydroxide to treat the crude of an intermediate compound, which not only facilitates the removal of residual copper ions from a catalyst, but also facilitates product precipitation.
(FR)L'invention concerne un procédé de préparation d'hydronidone. Le procédé comprend des opérations faciles, des conditions de réaction modérées, un temps de réaction court et un rendement élevé; le procédé est plus sûr et approprié pour une production à grande échelle. Le procédé utilise de l'hydroxyde d'ammonium pour traiter le brut d'un composé intermédiaire, qui non seulement facilite l'élimination d'ions de cuivre résiduels d'un catalyseur, mais facilite également la précipitation du produit.
(ZH)提供了一种羟尼酮的制备方法,操作简便、反应条件温和、反应时间短、产率高,更安全且适用于大生产。采用氨水处理中间化合物粗品,既有利于去除催化剂中残留的铜离子,又有利于产物析出。
