Abstract

A mathematical model for paired syntheses of 2‐butanone from 2,3‐butanediol in a packed bed flow reactor has been constructed. Model equations have been solved with a modified Shooting‐Runge Kutta numerical technique. Model calculations of current efficiencies and species concentrations are in good agreement with the experimental results. Calculations show that anodic reactions occur mainly in the front end of the anode. Bromine and bromate formation at the anode and acetoin reduction and hydrogen evolution at the cathode are charge‐transfer controlled. Rates of bromine and bromate reduction at the cathode are mass‐transfer controlled.
