- W2016298380 abstract "1, 3-Butanediol was pyrolyzed at 425°C in a batch reactor as a model system for liquefaction of lignocellulosic materials such as wood. The observed gas and liquid products were consistent with fragmentation, dehydration, and condensation/polymerization reaction pathways. Reaction in supercritical water altered the selectivity of the reactions to give mainly propene and formaldehyde. Dehydration and the formation of two-carbon products were suppressed by water. The conversion of 1, 3-butanediol in dilute aqueous solutions increased three to four fold when the reaction density was increased by 33%. Trace oxygen was an important inhibitor, particularly in the dilute solution, but had only a minor effect on the reaction selectivity.On a pyrolise du 1, 3-butanediol a 425°C dans un reacteur discontinu comme systeme modele pour la liquefaction de materiaux ligno-cellulosiques comme le bois. Les produits liquides et gazeux observes sont compatibles avec la fragmentation, la deshydratation et les reactions de condensation et de polymerisation. La reaction dans l'eau supercritique modifie la selectivite pour former principalement du propene et du formaldehyde. La presence d'eau fait disparaitre la deshydration et la formation de produits comportant deux carbones. La conversion du 1, 3-butanediol dans les solutions aqueuses diluees augmente par un facteur 3 ou 4 lorsqu'on augmente la densite du melange reactionnel de 33%. L'oxygene a l'etat de trace est un inhibiteur important particulierement en solution diluee, mais n'a qu'un effet mineur sur la selectivite." @default.
