Industrial Applications of Low-Field NMR Spectroscopy for Process and Quality Control of Silanes

  • The combination of different silanes as starting materials and as a product of hydrolysis by several alcohols or water creates a range of hundreds of technical products for a wide range of applications. In recent years, functional trialkoxysilanes have proven to be multi-purpose organosilanes. Applications range 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 spectrometers have the potential to be used in silane chemistry as an online method for reaction monitoring and quality control [1]. Interesting NMR nuclei for the above-mentioned products are 1H and 29Si. In a joint research cooperation between EVONIK and BAM, the applicability of low-field NMR spectroscopy for the chemical analysis of silanes was evaluated based on various case studies. In the course of the case studies it was shown how low-field NMRThe combination of different silanes as starting materials and as a product of hydrolysis by several alcohols or water creates a range of hundreds of technical products for a wide range of applications.

In the course of the case studies it was shown how low-field NMR spectroscopy extends the application range of chemical analysis to new applications where existing technologies such as NIR, Raman, UV/VIS, etc. cannot be used quantitatively due to lack of reference data.zeige mehrzeige weniger
