Title (EN) CATALYST FOR TETRAHYDROFURAN SYNTHESIS
(FR) CATALYSEUR POUR LA SYNTHÈSE DE TÉTRAHYDROFURANE
Abstract:
(EN) Provided are catalysts suitable for the production of tetrahydrofuran from 1,4- butanediol. Also provided are methods of use of these catalyst, as well as catalyst systems. The catalysts described herein contain only Lewis acidity, but not Br0nsted acidity, which results in decreased production of ether byproducts.
(FR) La présente invention concerne des catalyseurs appropriés pour la production de tétrahydrofurane à partir de 1,4-butanediol. L'invention concerne également des méthodes d'utilisation de ces catalyseur, ainsi que des systèmes de catalyseur. Les catalyseurs de l'invention contiennent seulement une acidité de Lewis, mais pas d'acidité Br0nsted, ce qui se traduit par une production réduite de sous-produits d'éther.
