Abstract: Disclosed is a microporous organic-inorganic hybrid silica membrane, supported by a mesoporous or macroporous layer. The microporous membrane has an average pore diameter of less than 1.5 nm. The silica contains moieties having divalent, trivalent or tetravalent organic groups between the silicon atoms of the following formulas: (see formula I, see formula VII, see formula VIII ) respectively, in which: m = 1 - 8; n = 2m, 2m-2, 2m-4, 2m-6, or 2m-8, provided that n >= 2; p = 0, 1, 2 or 3, and between 75 and 100% of the silicon atoms of the silica are bound to a carbon atom of organic groups. Also disclosed is a process for their preparation.

Abstract: A hydrothermally stable, microporous organic-inorganic hybrid membrane based on silica, having an mean pore diameter of between 0.2 and 1.5 nm, is characterised in that between 5 and 40 mole% of the Si-O-Si bonds have been replaced by mo ieties having the one of the formulas: Si-{[CH()X]-Si-}, Si-[CH()X]-Si or Si-CH-Si{(CH)-Si-} in which m = 1-8, n = 2m, 2m-2, 2m-4, 2m-6 or 2m-8; provided that n ≥ 2, X = H or (CH)Si, p = 0 or 1, and q = 1, 2, 3 or 4. The membrane can be produced by acid-catalysed hydrolysis of suitable bis- silane precursors such as bis(trialkoxysily)alkanes, preferably in the presence of monoorganyl-silane precursors such as trialkoxy-alkylsilanes.

Abstract: Selective retaining a relatively hydrophilic molecule from a mixture of a relatively hydrophobic molecule and the relatively hydrophilic molecule can be achieved using a hydrophobic, microporous hybrid membrane based on silica, wherein at least 25 % of the silicon atoms is bound to a bridging C1-C12-hyrdocarbylene group. The average number of carbon atoms of the bridging groups and any additional monovalent organic groups, taken together, is at least 3.5. The membrane can be part of a production facility for separating alcohol/water mixtures.

Abstract: A microporous organic-inorganic hybrid membrane based on silica of the invention has an average pore diameter of less than 0.6 nm, and comprises bridging organosilane moieties of the formula =O1.5Si-CHR-SiO1.5= or =O1.5Si-CH(CH3)-SiO1.5=. The membrane can be used in the separation of hydrogen from mixtures comprising hydrogen and CH4, CO2, CO, N2, and the like, and in the separation of water from alcohols having 1-3 carbon atoms, optionally in the presence of an inorganic or organic acid
