Abstract

Chemical transformations of surface-active substrate in the presence of surface-active catalyst are studied by the methods of computer simulation. Reactions occur in emulsion, at whose interfaces reactants are concentrated. It is established that there is an optimal size of emulsion droplets at which the reaction rate is the highest. It is shown that the kinetics of reactions substantially depends on the surface activity of reactants and the potential barrier of reaction. Under specific conditions, the rate of reaction notably increases during the initial time interval.
