Abstract:
The structure and stability of biogenic amine complexes formed at the fumed silica surface were studied by UV-, IR-spectroscopy and TPD MS techniques. It was found that surface complexes are formed due to electrostatic interactions between amine cations and ionized silanol groups. The mechanism of thermal transformations of surface complexes is proposed. Kinetic parameters of thermal reactions at the fumed silica surface have been calculated.
