Title (EN) METHOD FOR PRODUCING 1,3-PROPANE DIOL
(FR) PROCEDE DE PRODUCTION DE 1,3-PROPANE DIOL
(JA) 1,3−プロパンジオールの製造方法
Abstract: front page image
(EN)A method for producing 1,3-propane diol, characterized in that it comprises subjecting a crude 1,3-propane diol having a purity of 95 wt % or higher to a heating treatment in the presence of a base, and then distilling the resulting product for purification, to thereby provide a purified 1,3-propane diol as a distillate. The method provides a method for purification of 1,3-propane diol, which produces an 1,3-propane diol product being used for providing a polytrimethylene glycol exhibiting reduced discoloration.
(FR)La présente invention concerne un procédé de production de 1,3-propane diol, qui consiste à soumettre un 1,3-propane diol brut possédant une pureté de 95% en masse, voire au delà, à un traitement thermique en présence d'une base, puis à distiller le produit résultant de façon à le purifier, donnant ainsi un 1,3-propane diol purifié sous forme de distillat. Ce procédé comprend un procédé de purification du 1,3-propane diol qui produit un 1,3-propane diol utilisé pour fournir un polytriméthylème glycol présentant une décoloration réduite.
(JA)本発明の課題は、着色の少ないポリトリメチレンエーテルグリコールを与える1,3-プロパンジオールの精製方法を提供することである。本発明は、純度95重量%以上の粗1,3-プロパンジオールを塩基の存在下に加熱処理したのち、蒸留して精製1,3-プロパンジオールを留出させることを特徴とする1,3-プロパンジオールの製造方法に関する。
