An automatic lab scale equipment for continuous HMF production by the dehydration of fructose with homogeneous catalysis in biphasic systems (water solution -MIBK) was designed, manufactured and tested. The dependencies of the HMF yield on the process parameters were studied. The feed rate of fructose varied from 50 to 100 g•h -1 , the extractant (MIBK) flow rate from 0.5 to 1.4 L•h -1 and the process temperature was maintained in the range from 50 to 87 °C. The maximum productivity of the

This automatic lab scale equipment may be prospectively used for the kilogram scale HMF synthesis.
