At the current level of scientific and technological development, a special role is assigned to interfacial (IFC) processes. They are widely used in many chemical industries [1 – 4]. The tasks related to studying the issues of topology and mechanisms of response of IFC processes at the moment are extremely relevant and important.
Studying of distribution of reagents, products and the interphase catalyst between phases in a system liquid / liquid, identification of the main kinetic patterns on the example of reaction of an aminolysis of the activated N-benzyliumoxycarbonylglycine ether in the presence of the catalyst of interphase transfer – cetylpyridinium chloride (CPC) was an objective of this research.
The distribution of cetylpyridinium cation, as well as chloride, 4-nitrophenolate, glycinate-anions in the two-phase butanol-1/glycine buffer solution system (pH = 10.5) was studied by two main techniques (spectrophotomeric determination of ions in the separated aqueous and organic phases and study of the reaction rate in the two-phase system.
