- Abstract
Some new heterogeneous catalysts used to synthesize the tributyl citrate (TBC) and aspirin were prepared and characterized by brunauer-emmett-teller (BET), field emission scanning electron microscope (FE-SEM) and X-ray diffraction (XRD). The effect of temperature, catalyst loading and the concentration of oxidants on the catalytic efficiency of the catalyst were investigated. The results show that three ATP/t-AC catalysts namely ATP/t-AC-1, ATP/t-AC-2, ATP/t-AC-3 can be obtained by loading 60% aluminum dihydrogen tripolyphosphate (ATP) on oxidation modified activated carbon t-AC oxidized by Na2S2O8, H2O2, HNO3 respectively at 603K. For ATP/t-AC-1, when the concentration of Na2S2O8 increases to 0.75mol/L, the yield of aspirin increase to 86.6% while that of the TBC increase to 93%. For ATP/t-AC-2, when the concentration of H2O2 adds to 1 mol/L, the yield of aspirin increase to 86.7% while that of the TBC increase to 93%. For ATP/t-AC-3, the yield of TBC increase to 86.7% while the TBC increase is 97%with the concentration of HNO3 increases to 0.5mol/L. The ATP supported on the AC increase its specific surface area and improved its catalytic activity.
