Title (EN) PROCESS FOR THE PREPARATION OF A FURFURAL DERIVATIVE COMPRISING NEUTRALIZING AN ACID REACTION MIXTURE
(FR) PROCÉDÉ DE PRÉPARATION D'UN DÉRIVÉ DE FURFURAL COMPRENANT LA NEUTRALISATION D'UN MÉLANGE RÉACTIONNEL ACIDE
Abstract:
(EN) A furfural derivative having the chemical formula (1) (1) wherein R represents hydrogen, an alkyl group or an acyl group, is prepared in a process, which process comprises reacting a fructose-and/or glucose-containing starting material with a liquid hydroxyl group-containing compound of formula R-OH in the presence of an acid catalyst at a reaction temperature in the range of 150 to 300 ⁰C to produce a primary acid reaction mixture comprising the furfural derivative of chemical formula (1); separating part of the liquid hydroxyl group-containing compound from the primary acid reaction mixture to yield a secondary acid reaction mixture; neutralizing the secondary acid reaction mixture to a pH-value of at least 3 to obtain a neutralized reaction mixture; and purifying the neutralized reaction mixture to recover the furfural derivative of chemical formula (1).
(FR) La présente invention concerne un dérivé de furfural ayant la formule chimique (1) (1) dans laquelle R représente un atome d'hydrogène, un groupe alkyle ou un groupe acyle, est préparé dans un procédé, ledit procédé consistant à faire réagir un matériau de départ contenant du fructose et/ou du glucose avec un composé contenant un groupe hydroxyle liquide de formule R-OH en présence d'un catalyseur acide à une température de réaction dans la plage de 150 à 300 °C afin de produire un mélange réactionnel acide primaire comprenant le dérivé de furfural de formule chimique (1) ; séparer une partie du composé contenant un groupe hydroxyle liquide du mélange réactionnel acide primaire afin de donner un mélange réactionnel acide secondaire ; neutraliser le mélange réactionnel acide secondaire à une valeur de pH d'au moins 3 pour obtenir un mélange réactionnel neutralisé ; et purifier le mélange réactionnel neutralisé pour récupérer le dérivé de furfural de formule chimique (1).
