The present invention is a method for producing an organically modified airgel, 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 group and a nonpolar solvent; c) In the above method comprising the step of drying the organically modified gel subcritically, between step a) and step b) including a step for solvent exchange and / or for salt removal And the process is carried out in the absence of alcohol. Further disclosed is the use of the resulting organically modified airgel as a heat insulating or sound insulating material, as a catalyst support, gas storage means or as an adsorbent. |
