Title (EN) METHOD FOR PRODUCING 2-FURALDEHYDE
(FR) PROCÉDÉ DE PRODUCTION DE 2-FURALDÉHYDE
(JA) 2-フルアルデヒドの製造方法
Abstract: front page image
(EN)The present invention addresses the problem of providing a method for minimizing corrosion of a reactor device and reducing waste in the production of 2-furaldehyde from raw sugar that includes hexose as a constituent component, and addresses the problem of providing a method for producing 2-furaldehyde which minimizes decrease in the activity of a catalyst in a case where an acid catalyst is used, and has greater yield and is industrially advantageous. The present invention relates to a method for producing 2-furaldehyde, in which raw sugar having hexose as a constituent component is heated in the presence of a solid acid catalyst while in an aprotic polar solvent.
(FR)L'invention concerne le problème de fournir un procédé permettant de minimiser la corrosion d'un dispositif réacteur et de réduire les déchets dans la production de 2-furaldéhyde à partir du sucre brut qui comporte de l'hexose comme composant constitutif ; elle concerne également le problème de fournir un procédé permettant de produire 2-furaldéhyde qui minimise la diminution au niveau de l'activité d'un catalyseur dans le cas où un catalyseur acide est utilisé, qui a un plus grand rendement et qui est avantageux au plan industriel. L'invention concerne en outre un procédé de production de 2-furaldéhyde, dans lequel le sucre brut ayant l'hexose comme composant constitutif est chauffé en présence d'un catalyseur acide solide alors qu'il est dans un solvant polaire aprotique.
(JA) 本発明は、ヘキソースを構成成分として含む糖原料から、2-フルアルデヒドを製造するにあたり、反応装置の腐食を抑制し、廃棄物を低減する方法を提供することを課題とし、酸触媒を用いた場合の触媒の活性低下を抑制し、より収率の高い、工業的に有利な2-フルアルデヒドの製造方法の提供を課題とする。 本発明は、ヘキソースを構成成分とする糖原料を、固体酸触媒の存在下、非プロトン性極性溶媒中で加熱する2-フルアルデヒドの製造方法に関する。
