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...

Process Raman spectroscopy for the monitoring of distillations
Dr. Clemens Minnich, S-PACT
Among the thermal separation processes, distillation has the longest tradition and has already been used to separate spirits (alcohols) from fermented food. Thanks to its driving force, the differences in vapour pressure of the components in question, adding thermal energy is already sufficient t...

Online NMR spectroscopy empowered by Indirect Hard Modeling
Dr. Clemens Minnich, S-PACT
Nuclear Magnetic Resonance (NMR) spectroscopy has finally found its way into the Process Analytical Technology (PAT) toolbox. Powerful benchtop equipment capable of sampling-free online use, coupled with intelligent ways of chemometric spectral analysis, boosts the applicability of the technology...

Polymer formation from CO₂ - a Dream Production
Clemens Minnich, S-PACT
Gernot Nell, Parr Instrument Deutschland GmbH
Katrin Böhm, CAT Catalytic Center
The utilisation of CO₂ as a feedstock for chemical syntheses has been envisioned by chemists for a long time. However, its chemical inertness and the high activation energy prohibited many straightforward routes to generate value-added products from CO₂ so far. Recent developments in high-perform...
