Título (EN) PROCESS FOR THE PURIFICATION OF 1, 4-BUTANEDIOL
(FR) PROCEDE DE PURIFICATION DU 1,4-BUTANEDIOL
Resumo: front page image
(EN)A process for the purification of a crude liquid feed stream comprising 1,4-butanediol and a minor amount of 2-(4-hydroxybutoxy)-tetrahydrofuran and/or precursors thereof wherein the process comprises passing the crude feed in the presence of hydrogen in a reaction zone over a heterogeneous liquid tolerant copper catalyst in the liquid phase at hydrogenation conditions and recovering a purified stream of 1,4-butanediol having a lower amount of 2-(4-hydroxybutoxy)-tetrahydrofuran than the crude liquid feed stream.
(FR)La présente invention concerne un procédé pour la purification d’un flux d’alimentation liquide brut comprenant du 1,4-butanediol et une quantité mineure de 2-(4-hydroxybutoxy)tétrahydrofuranne et/ou de ses précurseurs. Le procédé comprend le passage de l’alimentation brute, en présence d’hydrogène, dans une zone de réaction sur un catalyseur au cuivre tolérant au liquide hétérogène en phase liquide à des conditions d’hydrogénation, et la récupération d’un flux purifié de 1,4-butanediol comportant une quantité de 2-(4-hydroxybutoxy)tétrahydrofuranne inférieure à celle du flux d’alimentation liquide brut.
