Abstract:
5-Hydroxymethylfurfural (HMF) is a bio-based platform chemical derived from cellulose. The conversion of glucose into HMF involves glucose isomerization into fructose and subsequent dehydration of fructose to HMF. Both steps need an acidic catalyst with suitable total amount of acid sites and proper ratio of Bronsted to Lewis acid sites to maximize the HMF yield. This study has focused on the synthesis of HMF from glucose in a one-pot process using biphasic solvent system (tetrahydrofuran and water) in the presence of sodium chloride. The reaction products were determined by a high-performance liquid chromatography. Niobium (Nb) is a strong acidic metal in isomerization and dehydration reaction. It has both Bronsted and Lewis acidity and exhibits a high-water tolerance. To increase Nb dispersion and active surface area, hexagonal mesoporous silica (HMS) and mesoporous carbon/silica nanocomposite (MCS) were used as catalytic support materials. The catalysts were characterized for their physicochemical properties by using various techniques. The effects of Nb loading, catalyst amount, reaction temperature and reaction time on the glucose conversion and the HMF yield were investigated. The results showed that the highest HMF yield of 57.9 % was achieved at 93.2 % glucose conversion over Nb supported on MCS (Nb/MCS) at 190 Celsius degrees for 1 h due to its suitable acid properties. The carbon presenting in MCS improved hydrophobicity of catalyst, which stabilized HMF molecule and inhibited rehydration of HMF to levulinic acid and formic acid.
