英文摘要The MCM-49 zeolite was successfully synthesized using an organic mixture solution (OMS) yielded from hydrogenation of caprolactam as the template instead of the pure hexamethyleneimine (HMI). The OMS contains HMI (76.0%similar to 84.0%), caprolactam (1.0%similar to 10.0%), water, and a few by-products. So the synthesis cost of the MCM-49 zeolite decreases obviously. The MCM-49 zeolite synthesized using OMS as the template shows similar crystallinity and purity to that synthesized using pure HMI in conventional process. From the results of NH3-TPD, N-2 adsorption isotherm, and DTA, it is evident that the MCM-49 zeolite possesses three kinds of acidic centers with different strength, and has a high specific surface area and good thermostability. Furthermore, the MCM-49 zeolite shows good catalytic behavior for the alkylation of benzene with dilute ethylene to ethylbenzene.
