中文摘要	Low melting systems consisting of ammoniumsalts and highly concentrated fructose were used for theconversion of fructose into 5-hydroxymethylfurfural (HMF). Not only acting as solvents, at sufficiently high temperatures, the ammoniumsalts themselves could also catalyse the dehydration of fructose to HMF. Among those salts, tetraethyl ammonium chloride (TEAC) was found to be the most efficientsolvent-catalyst, demonstrated by its ability to achieve 81.3% HMF yield with 33.3 wt% fructoseconcentration at 120 °C. 79.2% HMF yield was obtained with 50 wt% fructose concentration in the TEAC/fructose system using 5 mol% NaHSO₄·H₂O as a co-catalyst. A semi continuous biphasic system of TEAC/fructose/NaHSO₄·H₂O melt using tetrahydrofuran (THF) to recover HMF was proposed and demonstrated in a laboratory scale process operating at 120 °C. The impurities in the HMF recovered, involving TEAC and NaHSO₄·H₂O, were determined using ¹H NMR, elemental analysis and ICP-OES.

The impurities in the HMF recovered, involving TEAC and NaHSO(4)center dot H(2)O. were determined using (1)H NMR, elemental analysis and ICP-OES. (C) 2011 Elsevier B.V. All rights reserved.
