Quality control of silane mixtures with low-field NMR spectroscopy
Simon Kern , Clemens Minnich, S-PACT
In recent years, functional trialkoxy silanes have proven their versatility. After hydrolysis with water or alcohols, modified silanes are applied in numerous applications: from weather protection of buildings to bonding-imparting properties in the glass fiber industry, for sealants and adhesives, for coatings and paints to the modification of polymer materials.
Commercial benchtop NMR spectro-meters have the potential to be used in silane chemistry as an online method for reaction monitoring and quality control thanks to the presence of 29Si nuclei and the characteristic 1H fingerprints of the components.
