Recently, we have been involved in one research program to investigate the structure-directing ability of linear diquarternary alkylammonium ions with aliphatic and/or cyclic moieties in zeolite syntheses. In the present study, We have focused on the use of a new series of flexible, linear diquaternary alkylammonium ions(CH3)2(C2H5)N+(CH2)nN+(C2H5)(CH3)2 and (C2H5)2(CH3)N+(CH2)nN+(CH3)(C2H5)2 ions with n = 4-6 as structure-directing agents in the synthesis of this important class of microporous solids. Among the ammonium ions studied here, the Et4Me2-diquat-4 and Et4Me2-diquat-6 ions were found to be new structure-directing agents for the crystallization of MCM-47 and SSZ-16, respectively. |
