Rotating disk electrode (cont.) diffusion coefficient, 1141 diffusion layer in, 1234 disk current in, 1141 ECE reactions determination by. 1144 electrooxidation of methanol, 1139 kinematic viscosity, 1141,1234 intermediate radicals, determination of. 1139. 

Potentiodynamic curves were constructed for the oxidizing processes of benzene, chlorobenzene and diohlorobenzene v/ith the help of rotating disk electrode. At the range of potentials from 1.20 to 1.45V these curves pass the maximum (at 55°C). At more positive potentials one can see a current slump on the curves this fact testifies to a hindering of electrooxidation process.
