Formation of Intercalation Compounds of a Layered Sodium Octosilicate with n-Alkyltrimethylammonium Ions and the Application to Organic Derivatization

Abstract In this study, n-alkyltrimethylammonium ions ([CnH2n+1N(CH3)3]+; n = 12,14,16,18) were intercalated in the interlayer space of layered sodium octosilicate (Na2Si8O17·nH2O) via an ion-exchange reaction. The interlayer space was further modified by grafting of the trimethylsilyl groups via a reaction between a dodecyltrimethylammonium–octosilicate intercalation compound and chlorotrimethylsilane.
