A steady-state mathematical model of a parallel-plate reactor was developed for studying the electrochemical fluo- rination of organic compounds dissolved in anhydrous hydrogen fluoride. The model incorporates two-phase flow with differential material, energy, and pressure balances. Profiles of temperature, pressure, vapor volume fraction, and current density in the reactor are presented at two inlet temperatures to provide insight into the operation of the reactor. The effects of the inlet temperature, feed flow rate, and cell current on the cell pack voltage and current efficiency of the reac- tor are presented to determine problematic operating regions for the reactor. Optimum operating currents based on the ratio of the moles of fluorochemical produced to the input energy are also calculated.
