System-forming functions of bound water in the mechanism of topochemical reactions of formation of ultrathin layers on water surface

摘要

The system-forming role of the surface layer of water in the process of formation of ultrathin layers from the epoxide oligomer and triethylenetetramine or phosphotungstic acid on the surface of the aqueous phase is shown. Previously, this process was studied experimentally. The surface layer of the aqueous phase plays the role of a matrix, on which an epoxide oligomer monolayer and triethylenetetramine or phosphotungstic acid molecules are immobilized by hydrogen-bonding with water molecules from above or from below this matrix, respectively. Thus, topochemical reactions between the epoxide oligomer and triethylenetetramine or between the epoxide oligomer molecules in the presence of phosphotungstic acid become possible, so that ultrathin network epoxide-triethylenetetramine or epoxide layers are formed on the surface of water.
