Liquid-solid mass transfer coefficients in a rotor-stator spinning disc reactor are reported that were determined from measurements of reaction rates of the heterogeneously catalysed oxidation of glucose.The overall reaction rates are limited by both liquid-solid mass transfer and the intrinsic oxidation kinetics at the operating conditions used. The liquid-solid mass transfer increases with increasing rotational disc speed. The estimated liquid-solid mass transfer coefficient kLS increases from 1.5 · 10-4 m s-1 at 49 rad s-1 to 3 · 10-4 m s-1 at 181 rad s-1, which is at least a factor 3 higher than in conventional reactors.
