Description: Lactose, a by-product of the dairy industry, was used as a substrate for the production of 5-hydroxymethylfurfural (HMF)- a biofuel and polymer precursor. The combination of bronsted acid (acetic acid) and lewis acid (aluminum chloride) were analyzed in the presence of a green solvent- ?-valerolactone for the conversion of lactose to HMF. The thermochemical process was carried out on a digital stirring hot plate to enhance the mass transfer during the reaction. Three factors (temperature, reaction time and aluminum chloride catalyst concentration) were identified as the experimental factors and HMF yield as the response parameter. Central composite design with response surface methodology was used to optimize the reaction system. Optimal conditions found were: 0.01% mass fraction of aluminum chloride at 135 ?C for 100 min, affording 58.2 mol% of HMF yield. The study showed that the efficiency of the aluminum chloride varied with temperature, while acetic acid played a synergistic role with aluminum chloride in the reaction system. Moreover, the presence of formic acid, levulinic acid and humins were also detected and quantified.
