Influence of the donor properties of silica-immobilized amines on the thermodynamic characteristics of interfacial protolytic reactions

摘要

The thermodynamic characteristics of the reaction between amino groups covalently bonded to a silica surface and aqueous solutions of a strong acid were calculated. Data concerning the influence of the surface on the properties of the bonded amino groups and also about the interaction between neighbouring amines were obtained. The characteristics of the protonation process were explained in terms of a bonded layer structure.
