Raman spectroscopy solution for early hydrolysis detection in organo-trialkoxysilane

Overview

This solution leverages Raman spectroscopy to provide a rapid and non-destructive method for assessing early hydrolysis in organo-trialkoxysilane solutions. The technique tracks the decrease of the Si-OR symmetric stretch and the emergence of Si-OH and Si-O-Si bands, distinguishing between unreacted monomers, partially hydrolyzed species, silanols, and early oligomers. This approach is compatible with commercial handheld Raman analyzers, ensuring swift and accurate results catering to industrial needs.

Technical specifications

Key Features:

• Utilizes Raman spectroscopy to monitor spectral changes in Si-OR, Si-OH, and Si-O-Si bands
• Handheld and benchtop Raman analyzers provide results in seconds to minutes
• Chemometric calibration models (univariate and PLS) ensure quantitative reliability
• Minimal interference from water and solvents in complex mixtures

This solution is particularly suited for quality control processes where rapid and accurate hydrolysis detection is crucial. The system-specific calibration models enhance accuracy and are easily integrated into existing workflows.

Technology readiness level

The solution is currently at TRL 4, with plans to reach TRL 5-6 following further validation phases. Initial phases involve sample analysis and calibration model development, while later phases focus on testing under real conditions, refining the model, and integrating the solution into industrial processes. The total anticipated timeline for these phases is approximately 3-4 months.
