Abstract: The Interface-Reaction model proposed by the authors earlier for solid-liquid reactions was success fully applied to a typical moderate rate reaction, the hydrolysis of phthalic anhydride in aqueous solution of NaOH. This success in simulating non-instantaneous reaction strongly manifests the capability of the model in describing the behavior of some solid-liquid reactions. The jD factor for mass transfer in the reaction system equipped with flat-blade turbine agitator was found to increase with increasing Re for the first time, and the necessity of inclusion of Scm on the right hand side of jD-Re equations was also found in this work.
