摘要
The method of IR Fourier spectroscopy is used to study the physical nature of the molecular mechanism of vapor-phase extraction of low-molecular-weight organic acids C-2-C-6 from aqueous solutions. It is established that the characteristic absorption bands in the vibrational spectrum of the extracted component in the vapor phase are displaced, based on which it is concluded that intermolecular interactions exist between the molecules of the given component and the extractant in the vapor phase. The kinetic parameters of vapor-phase extraction are calculated for organic substances of structural form C-2-C-6. (c) 2008 Optical Society of America.
