Two Consecutive Reactions in Microscaled Electrolysis Cells

This work describes a container for electrolysis cells and electrodes that has been microscaled to demonstrate two consecutive reactions in a two-phase system. In the first step, reactive species, such as chlorine gas or bromine, are produced in the water phase of the electrolysis cell. In the second step, those reactive species diffuse to the upper phase to react with unsaturated oil triglycerides and produce a semi-solid product. The different configurations of the microscaled Hoffmann apparatus developed in this work present a convenient tool for student experiments or demonstrations.
