"Application of continuous flow and alternative energy devices for 5-hydroxymethylfurfural production";
Molecular Diversity, 15 (2011), 639 - 643.



English abstract:
Dehydration of fructose and glucose in dipolar,
aprotic solvents leads to formation of 5-hydroxymethylfurfural.
Conditions for continuous flow reactions using a
cartridge-based reactor system and a stop-flow microwave
reactor were established showing very good product yields
and selectivity without the limitation of a batch process such
as upscaling and precise temperaturemonitoring and control.
A maximum product HPLC yield of 90.3% under cartridgebased
heating and 85.6% under microwave heating could be
achieved using mild and quick reaction conditions. Formation
of levulinic acid as a by-product could not be detected
under the optimized reaction conditions.
