Abstract
Abstract: NMR and Raman spectroscopy studies were performed for different 3-aminopropyl(trimethoxy)- and 3-glycidoxypropyl(trimethoxy)silane based sol-gel systems containing different ketones. Exceptionally stable imine products were obtained depending on a reaction system at alkaline pH conditions and in the presence of water. These imine formation reactions were carried out without further catalyst. In addition, effect of water for the epoxy ring opening process was demonstrated, as well as the effect of solvents for the reaction path was confirmed. [Figure not available: see fulltext.]
