✦ Synopsis

The kinetic equations relating to the hydroxymethylation stage in base-catalyzed phenol-formaldehyde condensation have been developed as functions of the free phenol concentration. The same kinetic model was applied to the calculation of a continuous process carried out in a cascade of stirred tank reactors. The results obtained in batch and continuous experiments at 70, 80 and 9ff were compared with the corresponding calculated values.

## Abstract A mixing‐reaction model β€˜MIRE‐CSTR’ is developed to describe the selectivity behaviour mixing‐disguised reactions in continuous stirred tank reactors (CSTR). For competitive, consecutive reactions the general behaviour is demonstrated and a comparison with the behaviour in discontinuous
