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: Membranes of the invention comprise a hybrid silica film on a organic polymer support. The silica comprises organic bridging groups bound to two or more silicon atoms, in particular at least 1 of said organic bridging groups per 10 silicon atoms. The membranes can be produced by dry chemistry processes, in particular plasma-enhanced vapour deposition of bridged silane precursors, or by wet chemistry involving hydrolysis of the bridged silane precursors. The membranes are inexpensive and efficient for separation of small molecules and filtration processes.

Abstract: The invention provides a membrane suitable for dewatering acidic mixtures, comprising a bridged organosilica directly applied on a macroporous support in the absence of an intermediate mesoporous or finer layer. The bridged organic silica comprises divalent C1-C9 organic groups A2 and/or trivalent C1-C9 organic groups A3 directly bound to the silicon atoms of the organosilica. In particular, the membrane comprises bis-silylmethane or bis-silylethane groups. The membranes effectively separate water from acidic mixtures at high temperatures and without decrease in performance for at least several months.
