标 题:Hydrophobic zeolites with low silanol densities
发明人：FLAHERTY DAVID WILLIAM; BREGANTE DANIEL
权利人:UNIV ILLINOIS
摘要:A method for the synthesis of siliceous or heteroatom-substituted MFI zeolites (M-MFI; M=Si, Ti, Nb, or Ta) with tunable densities of SiOH that depend simply on the ratio of hydrofluoric acid (HF) to structure-directing agent (SDA; tetrapropylammonium hydroxide) used within the synthesis gel. The equilibrated ion exchange between OH − and F − ions forms tetrapropylammonium fluoride in situ, which does not lead to the formation of SiOH defects within M-MFI. Comparisons of infrared spectra from 15 distinct M-MFI materials show that the densities of SiOH groups within M-MFI decrease linearly with the ratio of HF:SDA, independent of the identity of the heteroatom within the framework.
