Abstract

Ultrasonic as a fast and powerful method was applied to prepare dendritic fibrous nanosilica (DFNSU) and the properties of this silica were compared with those of DFNS prepared by hydrothermal method (DFNSH). Using this support, a series of the Zn/DFNSU catalysts were prepared by incorporation of different zinc values using the co-condensation technique. The prepared catalysts were characterized by various methods (FT-IR, XRD, ICP, SEM, TEM, BET, and Py-FT-IR) and applied for direct production of hexyl levulinate from glucose. Among these catalysts, 40Zn/DFNSU exhibited the best results for the production of hexyl levulinate with 55.2% yield under optimum reaction conditions (0.05 g catalyst, 0.07 g glucose, reaction temperature of 200 °C and reaction time of 5 h). Also, the catalytic performance of Zn/DFNSH catalysts with different zinc values was studied under optimum reaction conditions and the maximum yield of hexyl levulinate was 59.2% in the presence of 40Zn/DFNSH catalyst.
