[en] hydroxymethylfurfural (5-HMF) ; furfural(2-F) ; monosaccharides
[en] The industrial trend is moving toward biobased plateform molecule preparation using biobased-processes integrating into green chemistry discipline. These “building blocks” molecules are intermediate for the synthesis of value-added chemicals. 5-hydroxymethylfurfural (5-HMF) and 2-furfural are two plateform molecules derived from monosaccharides.
In order to produce these furanic compounds, xylose and glucose conversion were conducted in hot deionized water, which represent the greenest solvent, at 211°C, 20 bars by means of batch-type reactor. A selected rang of times T1= 1min, T2=15 min , T3=30 min ,T4=45 min and T5 =60 min were investigated.
Results shows that at 15 min, the best 5-hydroxymethyl furfural ( 5- HMF) yield is 18,52%, produced by glucose dehydration, then it recorded a stable rate . At the same time 2-furfural was produced from xylose with a yield of 26,71% and didn’t vary significantly over time.
A 11, 09 % and 9,67 % yield of Lactic acid (LA) and Fromic Acid (FA) were obtained as a co-product from glucose dehydration and 5.53 % of LA was generated from xylose decomposition.
