Title
(EN) Synthesis method of oxo-isophorone
(ZH) 一种氧代异佛尔酮的合成方法
Abstract
(EN)
The invention relates to a synthesis method of oxo-isophorone. The method is characterized in that 3, 5, 5-trimethyl-4-hydroxyl-2-cyclohexene-1-one (HIP) is used as a raw material, p-benzoquinone compounds (II) are used as an oxidizing agent and a catalyst; oxygen or air is introduced, and an oxidation reaction is carried out in an inert solvent, so that the oxo-isophorone (KIP) and hydroquinone compounds (III) are generated.

(ZH)
一种氧代异佛尔酮的合成方法,其特征在于以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)。
