thesis / dissertation description
Hybrid organic/inorganic membranes were produced by chemical grafting of octadecyltrichlorosilane onto ?-alumina membranes. Separation factors are presented showing strong evidence of capillary condensation in ungrafted membranes. The grafted membranes exhibit a much improved separation factor, over the bare membranes, in the low-toluene feed concentration range. The separation factor appeared to decrease slightly with increasing feed toluene concentration, and it was approximately 1/8 the magnitude of the separation factors reported for polydimethylsiloxane under similar feed conditions.
