Abstract/OtherAbstract:
|
The surface modification of a layered alkali silicate, octosilicate (Na2Si8O17•nH2O), with sulfonic acid group was conducted. Sulfonic acid group was attached on the silicate layer by the reaction of octosilicate with phenethyl(dichloro)methylsilane and the subsequent sulfonation of the attached phenethyl groups with chlorosulfonic acid. The modified octosilicate is a solid acid as indicated by the intercalation of dodecylamine. A systematic expansion of the interlayer space was observed by the ion exchange with a series of alkyltrimethylammonium ions to show the variation of the layer charge density. |
