Abstract

The invention relates to a process for producing an organically modified aerogel, comprising the steps of a) reacting at least one soluble salt of an acidic or amphoteric oxygen-containing molecular anion with at least one acid to give a hydrogel, b) modifying the hydrogel with a mixture comprising a silylating agent having at least one organic radical and a nonpolar solvent, c) subcritically drying the organically modified gel, wherein the process does not comprise a step between step a) and step b) for exchange of the solvent and/or for removal of salts and the process is performed in the absence of alcohol. Additionally disclosed is the use of the organically modified aerogel obtained as a heat- or sound-insulating material, as a catalyst support, gas storage means or as an adsorbent.
