    Abstract: A process for preparing a porous material involves at least the steps of providing a mixture (I) containing a composition (A), which contains components suitable to from an organic gel, and a solvent (B); reacting the components in the composition (A) in the presence of the solvent (B) to form a gel; and drying of the gel. The composition (A) contains a catalyst system (CS), which contains at least a catalyst component (C1) selected from ammonium salts and phosphonium salts, and an acid with a phosphor containing acid group as a catalyst component (C2). Porous materials can be obtained in this way and the porous materials can be used as thermal insulation material and in vacuum insulation panels and vacuum insulation systems, in particular in interior or exterior thermal insulation systems as well as for insulation of refrigerators and freezers and in water tank or ice maker insulation systems.

    Abstract: The present invention relates to a process for preparing a porous material, at least comprising the steps of providing a mixture (I) comprising a water soluble polysaccharide, at least one compound suitable to react as cross-linker for the polysaccharide or to release a cross-linker for the polysaccharide, and water, and preparing a gel (A) comprising exposing mixture (I) to carbon dioxide at a pressure in the range of from 20 to 100 bar for a time sufficient to form a gel (A), and depressurizing the gel (A). Gel (A) subsequently is exposed to a water miscible solvent (L) to obtain a gel (B), which is dried. The invention further relates to the porous materials which can be obtained in this way and the use of the porous materials as thermal insulation material, for cosmetic applications, for biomedical applications or for pharmaceutical applications.
