Abstract

Organic derivatization of layered polysilicates (magadiite Na2Si14O29·xH2O and kenyaite K2Si20O41·xH2O) was performed by reaction of the tetraalkylammonium polysilicate intercalation compounds with chlorotrimethylsilane ((CH3)3SiCl) as the silylating agent. The formation of the organic derivatives was confirmed by X-ray powder diffraction, IR, 29Si MAS NMR, and elemental analysis, and revealed the bonding between the trimethylsilyl groups and the interlayer silanol groups. The advantage of using tetraalkylammonium polysilicate intercalation compounds as intermediates for organic derivatization is elucidated.
