Title (EN) A PROCESS FOR MAKING BUTYL ETHERS OF GLYCOLS
(FR) PROCEDE DE PREPARATION D'ETHERS BUTYLIQUES DE GLYCOLS
Abstract: front page image
(EN)Processes are described for the preparation of glycol butyl ethers involving reaction of butadiene with saturated aliphatic glycols, separating the thus formed n- and sec-butenyl glycol ethers and hydrogenating the n-butenyl glycol ethers. Additional features are the use in the first step of heterogeneous catalyst modified by alkylpyridinium quaternary ammonium, quaternary arsonium quaternary phosphonium counterions and/or the conversion of sec-butenyl glycol ethers to butadiene and saturated aliphatic glycols.
(FR)L'invention concerne des procédés de préparation d'éthers butyliques de glycol impliquant la réaction d'un butadiène avec des glycols aliphatiques saturés, la séparation des éthers de glycol de n-butényle et sec-butényle, et l'hydrogénation des éthers de glycol de n-butényle. Dans d'autres aspects, l'invention consiste à utiliser dans la première étape un catalyseur hétérogène modifié par des contre-ions d'ammonium, arsonium et phosphonium quaternaires d'alkylpyridinium, et/ou à convertir les éthers de glycol de sec-butényle en butadiène et en glycols aliphatiques saturés.
