size filter, and then analyzed by a Dionex ICS-3000 High
Pressure-Anion Exchange Chromatograph (HP AEC) equipped
with a Carbopack PA20 column and a Pulsed Ampherometric
Detector (PAD) to identify unreacted glucose. 18 mM sodium
hydroxide was used as mobile phase and the temperature of the
column was kept at 303 K.
The conversion of glucose was based on the concentration of
products obtained multiplied by 100 and divided by the concen-
tration of substrate used. Further, selectivity was calculated as
concentration of a particular product obtained multiplied by 100
and divided by the concentration of total products. Furylhydrox-
ymethyl ketone (FHMK) and 5-chloromethylfurfural (CMF)
were quantified using HMF calibration data since they have
an almost similar type of structure to HMF and could not be
obtained commercially.

We have shown that heteropoly acids are very good cat-
alysts for promoting the dehydration of glucose to 5-
hydroxymethylfurfural (HMF) in ionic liquids, particularly in
the presence of acetonitrile as a cosolvent. Using 12-MPA as the
catalyst, it was possible to achieve a glucose conversion of 98%
with a HMF selectivity of 99% after 3 h of reaction at 393 K
in a mixture of either EMIMCl or BMIMCl and acetonitrile.
The observed selectivity to HMF was much higher than that
observed using liquid acids. With the exception of phosphoric
acid, liquid acids exhibited moderate selectivity to FHMK and,
in some cases, CMF. It is proposed that the HMF high selectivity
of heteropoly acids is attributable to stabilization of the reaction
intermediates involved in formation of HMF (see Scheme 1). A
key intermediate in the reaction pathway to HMF is believed to
be 1,2-enediol. We propose that acid-catalyzed isomerization of
this species to 2,3-enediol leads to the formation of FHMK. In
the absence of acetonitrile as a cosolvent, moderate amounts
of humins were formed. Hydrogenation of HMF in a mixture
of EMIMCl and acetonitrile promoted by carbon-supported
transition metals produced a series of products, and in particular
DMF, a product of particular interest because of its high-
energy content. The highest yield of DMF was obtained using
Pd/C. The reaction pathway by which HMF is converted to
DMF was explored by using the intermediates as starting
materials. It was also observed that HMF produced by the
dehydration of glucose in the presence of 12-MPA could be
converted to DMF (after removal of 12-MPA and replacement
by Pd/C) with the same yield as that obtainable by starting
with pure HMF. In summary, this study shows that it is possible
to dehydrate glucose to HMF in IL–acetonitrile solution with
near 100% yield and to convert HMF to DMF with reasonable
yield by subsequent hydrogenation under relatively mild reaction
conditions.
