Show more >The design of an “H”-shaped reactor has been studied to satisfy the possibility of using a triphasic medium to transform d-glucose into 5-hydroxymethylfurfural (HMF) by a hybrid catalytic process using an immobilized glucose isomerase, allowing the isomerization of D-glucose to d-fructose, and a heterogeneous chemical catalyst to catalyze the dehydration of d-fructose to HMF. The various parameters influencing the transport of d-fructose within the reactor were studied, namely the difference in pH between the two aqueous phases, the agitation and the quantity of 3,4-DCPBA/Aliquat336® used to extract and transport continuously the d-fructose. The pH discrepancy, which must be between 5.0 and 5.5, turns out to be the real driving force behind the extraction of D-fructose. The D-Fru/3,4-DCPBA molar ratio of 1/0.25 allowed the transport of more than 80 % of the D-fructose initially present and shows that the same molecule of 3,4-DCPBA is involved at least twice in the transport of D-fructose and that the 3,4-DCPBA/Aliquat336® couple performs a turnover within the organic phase. Finally, a HMF production yield of 30.9 % and an isomerization yield of 79.1 % were obtained, illustrating the shift in the isomerization equilibrium made possible by a D-fructose extraction yield of 96.8 %.Show less >
