3‐Methyl‐3‐penten‐2‐one (3M3P) is an indispensable raw material used for the synthesis of OTNE (octahydrotetramethyl acetophenone), a synthetic ketone fragrance known by commercial trade names, such as Iso E Super®, which is one of the most important ingredients in perfumes. This work is the first to unravel the reaction route and kinetics for the synthesis of 3M3P via the cross‐aldol condensation of acetaldehyde with butanone, catalyzed by the heterogeneous acidic ion exchange resin (NKC‐9).

揭示合成酮香料的3-甲基-3-戊烯-2-酮合成的反应路线和动力学

3-甲基-3-戊烯-2-酮（3M3P）是用于OTNE（octahydrotetramethyl苯乙酮），合成酮香料由商业商品名，如公知的合成中不可缺少的原料异ëSuper®，这是一个香水中最重要的成分。这项工作是第一个揭示通过异质酸性离子交换树脂（NKC-9）催化的乙醛与丁酮的羟醛缩合反应合成3M3P的反应路线和动力学的方法。
