چکیده
In this paper, differences of infrared spectra hydrate formation inhibitors thermodynamic and kinetic action types were investigated. The method was proposed for determining the type a inhibitor by its spectrum. relevance is due to expressiveness in comparison with testing laboratory tests. It use Fourier transform spectrometry. allows us obtain data on molecular intermolecular interactions substance under study. obtained mode attenuated total reflection analyzed principal component analysis regression projection latent structures, which are related chemometric methods make it possible identify key features compositions that affect mechanism their action. separation sample studied into two subgroups, represent different action, obtained. makes reagents For inhibitors, characteristic ratio amplitudes vibrations –OH N–H functional groups internal standard spectrum revealed. shown decisive factor division difference between resonant vibration frequencies corresponding valence C–O, C–N bonds organofluorine compounds. At same time, similarity amplitude indicated spectral regions noted. group most influential bands IR symmetric asymmetric stretching C–H CH2 CH3 groups. There significant increase range 2950–2750 cm–1 compared signal 3300–3400 1200–1100 cm–1, also found inhibitors. structures used develop model determine express determination Results could be oilfield chemistry prevent gas hydrates during production, preparation or transportation hydrocarbons.
