Organic-templated silica membranes: I. Gas and vapor transport properties
A novel and efficient method for molecular engineering of the pore size and porosity of microporous sol-gel silica membranes is demonstrated in this communication. By adding a suitable organic template (e.g. tetraethyl- or tetrapropylammonium bromide) in polymeric silica sols, otherwise known to result in microporous membranes with pores in the range 3-4A, we can ‘shift’ the pore size to 5-6A, as judged by single-component gas and vapor permeation results with probe molecules of increasing kinetic diameter (dk). The templated membranes exhibit permeances as high as 10-7 to 10-6molm-2s-1Pa-1 for molecules with dk<4.0A (e.g. CO2, N2, CH4), coupled with single-component selectivities of 100-1800 for N2/SF6, 20-40 for n-butane/iso-butane, and 10-20 for para-xylene/ortho-xylene. The transport properties of the templated membranes are distinctly different from those of the respective silica membranes prepared without templating, and resemble somewhat the transport properties of polycrystalline zeolite MFI membranes prepared by the lengthy, batch hydrothermal synthesis approach, using tetrapropylammonium bromide as a structure directing agent. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Computed Properties of C12H28BrN, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1941-30-6, in my other articles.
