The possibility of intensifying fast chemical processes at the interface of two-component liquid medium in a tubular turbulent reactor has been considered. A new application of the turbulent reactor for processes occurring at interfaces in two-component liquid systems has been found. It has been observed that the chemical reaction time abruptly decreases, and the physics of the process affects the direction of and conversion in the chemical reaction at a high (up to 100%) yield of desired products. The geometric characteristics of the reactor have been analyzed, and it has been shown that the dispersion of drops in the emulsion is most efficient at large angles of inclination of an obstruction to the flow and at minimal gaps in the convergent-divergent channel of the reactor. It has been demonstrated that the average perimeter of drops of the dispersion oscillates with time, which causes elongation and breakup of drops. In its turn, the latter influences the contact surface area of the emulsion and, significantly, the chemical reaction rate.
