| description | This SO<sub>4</sub>/TiO<sub>2</sub> catalyst as a heterogeneous acidic catalyst was synthesized in various concentrations of H<sub>2</sub>SO<sub>4</sub>. The activity and selectivity of the SO<sub>4</sub>/TiO<sub>2</sub> catalyst on the dehydration reaction of ethanol to diethyl ether were studied as well. The SO<sub>4</sub>/TiO<sub>2</sub> was prepared from TiO<sub>2</sub> powder by wet impregnation method with a various aqueous solution of H<sub>2</sub>SO<sub>4</sub> (1; 2; 3 M H<sub>2</sub>SO<sub>4</sub>) and calcination temperature (400, 500, and 600 °C) to obtain a catalyst with optimum acidity. The catalysts were characterized using FTIR, XRD, SEM-EDX, SAA, TGA/DSC, and acidity test gravimetrically with ammonia. The liquid product of DEE was analyzed by gas chromatography (GC) to analyze the selectivity of the catalyst. The catalyst TS-3-400 had the highest activity and selectivity in the dehydration reaction of ethanol to diethyl ether at a temperature of 225 °C, with a conversion of 51.83% and a DEE selectivity of 1.72%. |
