Title (EN) METHOD FOR PRODUCING 4-METHYLPENTANAL
(FR) PROCÉDÉ DE PRODUCTION DE 4-MÉTHYLPENTANAL
(JA) 4-メチルペンタナールの製造方法
Abstract: front page image
(EN)[Problem] To provide a method for producing 4-methylpentanal efficiently and at good yield. [Solution] A method for producing 4-methylpentanal through the following steps. Step 1: Obtain 3-methyl-1-butanol by hydrogenating 3-methyl-3-buten-1-ol; Step 2: obtain 3-methyl-1-butene by dehydrating the 3-methyl-1-butanol obtained in step 1; Step 3: obtain 4-methylpentanal by hydroformylating the 3-methyl-1-butene obtained in step 2.
(FR)L'objectif de la présente invention est de mettre au point un procédé de production de 4-méthylpentanal qui est efficace et présente un bon rendement. A cette fin, l'invention concerne un procédé de production de 4-méthylpentanal comprenant les étapes suivantes. Étape 1 : obtenir du 3-méthyl-1-butanol par hydrogénation de 3-méthyl-3-butène-1-ol ; Étape 2 : obtenir du 3-méthyl-1-butène par déshydratation du 3-méthyl-1-butanol obtenu à l'étape 1 ; Étape 3 : obtenir du 4-méthylpentanal par hydroformylation du 3-méthyl-1-butène obtenu à l'étape 2.
(JA)【課題】4-メチルペンタナールを収率よくかつ効率的に製造する方法を提供すること。 【解決手段】以下の工程を経由する4-メチルペンタナールの製造方法。 工程1:3-メチル-3-ブテン-1-オールを水素添加して3-メチル-1-ブタノールを得る; 工程2:工程1で得た3-メチル-1-ブタノールを脱水させて3-メチル-1-ブテンを得る; 工程3:工程2で得た3-メチル-1-ブテンをヒドロホルミル化して4-メチルペンタナールを得る。
