RAMAN SPECTRUM OF AMINOPROPYLSILANETRIOL IN VAPOR
Aminopropylsilanetriol (APST) is one of the most frequently used organofunctional silane coupling agents. This molecule also emerges through the hydrolysis of other alkoxysilanes as a product of hydrolysis. Because of its two functional groups located at the opposite molecular sites, it can react with organic polymers as well as with inorganic substrates and fillers. Conformational stability and vibrations of APST has been investigated using DFT calculations, but the vibrational spectra were recorded only for water solution and condensed, polymerized structure. In this work we present Raman spectrum of APST in vapor phase. In order to get Raman spectra of vaporized APST the following procedure was used: 25% water solution of APST was filled in glass capillary and frozen in liquid nitrogen bath. The capillary was then connected to the vacuum pump in order to evacuate all the air above the sample. After evacuation the capillary was sealed and left at room temperature. Raman spectra of solid, solution and of the evaporated sample above solution were recorded at room temperature.
