| 英文摘要: |
| Aluminophosphate molecular sieve, AlPO 4 12, was synthesized using ethylenediamine as a templating agent in the hydrothermal system. Effects of pH value of the initial reaction mixture and the amount of ethylenediamine used on crystalline phase of the products were investigated. The chemical compositions of the sample are consistent with the literature data. The synthetic AlPO 4 12 samples were characterized using XRD, SEM, IR, DTA, chemical analysis and adsorption measurement. The catalytic performance of AlPO 4 12 molecular sieve in the esterification of propionic acid with n butanol was examined. The results show that AlPO 4 12 possesses good adsorption properties for water and cyclohexane, high thermal stability, and high catalytic activity for the esterification of propionic acid with n butanol. |
