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: La presente invención se refiere a una membrana híbrida orgánica-inorgánica microporosa, hidrotérmicamente estable, basada en sílice, que tiene un diámetro de poro medio de entre 0.2 y 1.5 mm, se caracteriza en que entre 5 y 40% mole de los enlaces Si-O-Si han sido reemplazados por porciones que tienen una de las fórmulas Si-{[CmH(n-1)X]-Si-}q, Si-[CmH(n-2)X2]-Si o Si-CmHn-Si{(CmHn)-Si-}y en la cual m = 1-8, n = 2m, 2m-2, 2m-4, 2m-6 o 2m-8; siempre que n ( 2, X = H o (CH2)pSi, p = 0 o 1, y q = 1, 2, 3 o 4. La membrana puede ser producida por hidrólisis catalizada por ácido de precursores de bis-silano tales como bis(trialcoxisili)alcanos, preferiblemente en la presencia de precursores de monoorganil-silano tales como trialcoxi-alquilsilan os.

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mean pore diameter of between 0.2 and 1.5 nm, is characterised in that between 5 and 40 mole% of the Si-O-Si bonds have been replaced by mo ieties having the one of the formulas: Si-{[CH()X]-Si-}, Si-[CH()X]-Si or Si-CH-Si{(CH)-Si-} in which m = 1-8, n = 2m, 2m-2, 2m-4, 2m-6 or 2m-8; provided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.
