6.4 Biphasic Electrolytic Systems
In general, electrochemical reactions are
carried out in homogeneous electrolytic
solutions. However, the electrochemical
reaction can be conducted even in
heterogeneous electrolytic solutions unless both
electron transfer and mass transfer processes
are not inhibited by the reaction system. In this
section, we will discuss biphasic electrolytic
systems such as emulsion electrolysis,
suspension electrolysis, electrolysis using phase
transfer catalysis and the thermomorphilic
biphase electrolytic reaction system [13-15].
6.4.1 Emulsion Electrolysis
As shown in Figure 6.7 , when the product is an
oxidizable and reducible compound such as an
aldehyde, an organic phase in a biphasic
