Zur Kinetik der Bildung von 5‐Hydroxymethylfurfural

Abstract: Zur Kinetik der Bildung von 5-Hydroxymethylfurfural F. ORSI 547.724.2.07 5-Hydroxymeth ylfurfural-BildungIn Glucoselosungen mit Molenbriichen von 0,015-1,000 wurde die Kinetik der Bildung von 5-Hydroxymethylfurfural im Temperaturbereich 120 bis zoo "C untersucht. Auf Grund von Vorversuchen zeigte es sich, daD zur Bestimmung des 5-Hydroxymethylfurfurals die vom Verfasser modifizierte WINKLERSChe Methode gut anwendbar ist. Mit der Bildung von storenden Mengen des 5-Methylfurfurals ist nur bei hohen Temperaturen … Show more

“…The selectivity of the dehydration reactions of fructose (and glucose) towards H M F is enhanced by an increase in temperature. This effect has been explained by differences in activation energies for the formation (29 [17], 34 [8] and the rehydration (23 [7], 26 [9] kcal/mole) of H M F [lo]. A factor that seems to have been overlooked in the literature is the effect of the temperature on the anomeric equilibria of the starting compounds.…”
