Liu, Hemei published the artcilePreparation and application of zeolite based on the novel binuclear aromatic quaternary ammonium template, Related Products of dioxole, the publication is Shandong Huagong (2014), 43(11), 113-117, database is CAplus.
A novel binuclear aromatic quaternary ammonium template was synthesized, and its structure was characterized by NMR and IR. On this basis, a new type of ZSM-5 zeolite with MFI-type diffraction peaks was prepared The ZSM-5 zeolite was characterized by XRD, SEM, NH3-TPD and N2-adsorption-desorption. The novel HZSM-5 zeolite’s catalytic performance in condensation reaction of ethylene glycol and cyclohexanone was studied in detail. Then, the influences of zeolite dosage, reaction time and temperature on the Ketalization were investigated in order to optimize the reaction condition. Furthermore, the recycling of mol. sieve was organized under optimal reaction conditions. Subsequently, the HZSM-5 zeolite was modified by chlorosulfonic acid in order to improve the catalytic activity. After that, the ketalization catalyzed by the modified HZSM-5 zeolite under the optimal reaction conditions was investigated. The results revealed that the zeolite had high catalytic activity, good stability, easy recycling, easy separation of catalyst and few pollution, which can be used as an efficient and environmentally friendly green solid acid.
