Abstract: This study aimed to evaluate the synthesis and application of heterogeneous catalysts based on heteropolyacids for 5-hydroxymethylfurfural (HMF) production from glucose. Initially, assays were carried out in order to establish the most favorable catalyst synthesis conditions. For such purpose, calcination temperature (300 or 500 °C), type of support (Nb 2 O 5 or Al 2 O 3 ), and active phase (H 3 PW 12 O 40 —HPW or H 3 PMo 12 O 40 —HPMo) were tested and combined based on Taguchi’s L 8 orthogonal array. As a result, HPW-Nb 2 O 5 calcined at 300 °C was selected as it presented optimal HMF production performance (9.5% yield). Subsequently, the reaction conditions capable of maximizing HMF production from glucose using the selected catalyst were established. In these experiments, different temperatures (160 or 200 °C), acetone-to-water ratios (1:1 or 3:1 v/v ), glucose concentrations (50 or 100 g/L), and catalyst concentrations (1 or 5% w/v ) were evaluated according to a Taguchi’s L 16 experimental design. The conditions that resulted in the highest HMF yield (40.8%) consisted of using 50 g/L of glucose at 160 °C, 1:1 ( v/v ) acetone-to-water ratio, and catalyst concentration of 5% ( w/v ). Recycling tests revealed that the catalyst can be used in four runs, which results in the same HMF yield (approx. 40%).
