Study on adsorption and desorption of phenoxycarbonic acids on silica surface
Adsorption of lines phenolic connections with various functional groups on a silica surface is investigated. The contribution of waterproof interaction and formation of hydrogen bonds with carboxyl and hydroxyl protons in adsorption’s process is determined. By temperature-programmed desorption mass...

Surface| Резюме: | Adsorption of lines phenolic connections with various functional groups on a silica surface is investigated. The contribution of waterproof interaction and formation of hydrogen bonds with carboxyl and hydroxyl protons in adsorption’s process is determined. By temperature-programmed desorption mass spectrometry was determines dependence of thermal stability phenolic connections from a structure of molecules and adsorption on silica.
The method of a nuclear magnetic resonance of the high sanction in conditions frosting a liquid phase establishes dependence of superficial energy ｧs, on a structure of the present molecules phenolic connections.
Therefore, one can distinguish two types of interaction of phenolic connections with silicon dioxide surface: specific interaction with surface silanol groups and nonspecific interaction with carbohydrate component of methyl-silica surfaces.
