Title (EN) METHOD FOR PRODUCING PROPYLENE GLYCOL
(FR) PROCÉDÉ DE PRODUCTION DE PROPYLÈNE GLYCOL
(JA) プロピレングリコールの製造方法
Abstract: front page image
(EN)Disclosed is a method for producing propylene glycol using glycerin as a raw material, which does not require a step for evaporating glycerin. Specifically disclosed is a method for producing propylene glycol, which is characterized by comprising a step for obtaining propylene glycol by catalytically hydrogenating glycerin in the presence of a catalyst A containing zinc oxide, silica, and at least one of copper and copper oxide.
(FR)La présente invention a trait à un procédé de production de propylène glycol utilisant de la glycérine en tant que matière première et n'exigeant pas d'étape d'évaporation de la glycérine. L'invention a, plus précisément, trait à un procédé de production de propylène glycol, caractérisé en ce qu'il comprend une étape d'obtention de propylène glycol par hydrogénation catalytique de la glycérine en présence d'un catalyseur A contenant de l'oxyde de zinc, de la silice et au moins l'un des composés choisis parmi le cuivre et l'oxyde de cuivre.
(JA) 本発明は、グリセリンを原料とするプロピレングリコールの製造方法において、グリセリンを気化する工程を必要としないプロピレングリコールを製造する方法を提供することを目的とする。  本発明のプロピレングリコールの製造方法は、銅および酸化銅の少なくとも一方,酸化亜鉛およびシリカを含む触媒Aの存在下で,グリセリンを接触水素添加してプロピレングリコールを得る工程を含むことを特徴としている。
