| titleOfInvention | Method for producing organically modified aerogel using alcohol, in which salt precipitates during the production process |
| abstract | (57) Abstract: The present invention relates to a) producing a silicic acid sol having a pH ≦ 4.0 from an aqueous potassium silicate solution using at least one organic and / or inorganic acid, and b) producing silicic acid The sol is polycondensed by adding a base to an SiO 2 gel, and the gel obtained in c) step b) is washed with an organic solvent until the water content of the gel becomes 5% by weight or less, and d) step The present invention relates to a method for producing an organically modified airgel, wherein the gel obtained in c) is surface-modified with at least one C 1-6 alcohol, and e) the surface-modified gel obtained in step d) is dried. The method is characterized in that the at least one acid forms a potassium silicate cation and a salt which is sparingly soluble in the silicate sol. Before step b), the poorly soluble salt formed is thoroughly precipitated and separated from the silica sol. |
