Abstract
(EN)
Provided is a method for synthesizing keto-isophorone. The method comprising: using 3,5,5-trimethyl-4-hydroxy-2-cyclohexene-1-one (HIP) as a raw material; using a benzoquinone compound (II) as an oxidizing agent and a catalyst; introducing oxygen or air; oxidizing an inert solvent to generate a keto-isophorone (KIP) and a hydroquinone compound (III);
(FR)
L'invention concerne un procédé de synthèse céto-isophorone. Ce procédé comprend; l'utilisation de 3,5,5-triméthyle-4-hydroxy-2-cyclohexène-1-one (HIP) comme matière première; l'utilisation d'un composé de benzoquinone (II) comme agent oxydant et catalyseur; l'introduction d'oxygène ou d'aire; et l'oxydation d'un solvant inerte en vue de générer une céto-isophorone (KIP) et un composé d'hydroquinone (III).
(ZH)
本发明公开了一种氧代异佛尔酮的合成方法,以3,5,5-三甲基-4-羟基-2-环己烯-1-酮(HIP)为原料,对苯醌类化合物(II)为氧化剂和催化剂,通入氧气或者空气,在惰性溶剂中进行氧化反应,生成氧代异佛尔酮(KIP)和对苯二酚类化合物(III)。
