A silicon-29 NMR study of the structural intermediates in low pH sol-gel reactions

  • L. W. Kelts (a1) and N. J. Armstrong (a1)
Abstract

Silicon-29 NMR is used to study the structural intermediates in tetramethyl and tetraethyl orthosilicate (TMOS and TEOS) low pH sol-gel reactions. Differences in the number of compact ring structures are related to differences in gel times. Reactions are followed at various silicon: water: acid molar ratios.

13Klemperer W. G. has recently suggested that MeOH and HCl in these solutions will form MeCl and H2O (“Molecular Growth Pathways in Silica Sol-Gel Polymerization,” a seminar at the Better Ceramics through Chemistry III, April 1988, MRS Spring Meeting, Reno, NV). This reaction could account for a large amount of the extra hydrolysis observed, but we don't see its formation.
