Title
(EN) PROCESS FOR THE PRODUCTION OF KETOISOPHORONE DERIVATIVES AND EQUIPMENT THEREFOR
(FR) PROCEDE DE PRODUCTION DE DERIVES DE CETOISOPHORONE ET INSTALLATION A CET EFFET
Abstract
(EN)
Ketoisophorone derivatives represented by general formula (2) are produced by oxidizing a $g(b)-isophorone derivative represented by general formula (1) in the presence of an oxidation catalyst in a solvent substantially free from acid components (organic carboxylic acids). The amount of acid components in the solvent may be 0 to 4000 ppm (by weight), and complex salts of transition metals with N,N'-disalicylidenediamine can be used as the oxidation catalyst. Further, cyclic bases may be used in the above oxidation as the promoter, and the solvent separated from the resulting reaction mixture may be freed from acid components and then recycled for the oxidation.
(FR)
Pour produire les dérivés de cétoisophorone représentés par la formule générale (2), le procédé de la présente invention consiste à oxyder un dérivé de $g(b)-isophorone représentés par la formule générale (1) en présence d'un catalyseur d'oxydation dans un solvant sensiblement exempt de composants acides (acides carboxyliques organiques). La teneur massique du solvant en composants acides peut aller de 0 à 4000 ppm. Le catalyseur d'oxydation à utiliser peut être un complexe de sels de métaux de transition et de N,N'-disalicylidènediamine. En outre, comme promoteur pour l'oxydation on peut utiliser des bases cycliques. Le solvant récupéré du mélange de réaction résultant se prête à une suppression de ses composants puis au recyclage en vue de l'oxydation.
