    • 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.
    • 本发明涉及一种生产有机改性气凝胶的方法,包括以下步骤:a)使至少一种酸性或两性含氧分子阴离子的至少一种可溶性盐与至少一种酸反应得到水凝胶,b)改性水凝胶 与包含具有至少一个有机基团和非极性溶剂的甲硅烷基化剂的混合物,c)亚临界干燥有机改性的凝胶,其中该方法不包括步骤a)和步骤b)之间用于交换溶剂和/ 或用于除去盐,并且该方法在不存在醇的情况下进行。 另外公开了获得作为隔热材料或隔音材料的有机改性气溶胶作为催化剂载体,气体储存装置或吸附剂的用途。
