Title (EN) PROCESS FOR PRODUCING DIACETONE ALCOHOL
(FR) PROCEDE DE PRODUCTION D'ALCOOL DIACETONE
(JA) ジアセトンアルコールの製造方法
Abstract: front page image
(EN)A process for diacetone alcohol production in which a long-term operation is possible. The process comprises producing diacetone alcohol from acetone in the presence of a solid basic catalyst comprising at least (i) a metal hydroxide selected among the hydroxides of alkali metals and the hydroxides of alkaline earth metals and (ii) a binder, and is characterized by using as the solid basic catalyst one in which the volume of pores having a diameter of 0.01 to 1 μm is 1.8 ml/g or larger.
(FR)L'invention concerne un procédé de production d'alcool diacétone permettant une opération longue durée. Ce procédé consiste à produire de l'alcool diacétone à partir d'acétone en présence d'un catalyseur basique solide contenant au moins (i) un hydroxyde de métal choisi dans les hydroxydes de métaux alcalins et les hydroxydes de métaux terreux alcalins, et (ii) un liant, et se caractérise par l'utilisation d'un catalyseur solide basique comprenant des pores qui présentent un volume égal ou supérieur à 1,8 ml/g, pour un diamètre de 0,01 à 1 $g(m)m.
(JA)本発明の課題は、長期運転が可能なジアセトンアルコールの製造方法を提供することにある。本発明は、少なくとも(i)アルカリ金属水酸化物およびアルカリ土類金属水酸化物から選ばれた金属水酸化物と(ii)結合剤からなる固体塩基性触媒の存在下、アセトンからジアセトンアルコールを製造する方法において、固体塩基性触媒として、細孔径0.01~1μmの細孔容量が1.8ml/g以上であるものを用いることを特徴とするジアセトンアルコールの製造方法に係わる。
