Abstract

The chemical reactor is based on a cylindrical vessel with a stirring device. The stirring device consists of a magnetic stirrer 3, 5, 11a, 11b, 12 with magnetic coils which are disposed around the outside of the cylindrical vessel 1 in the form of a star and produce a magnetic field and of a rotor 3 which is mounted in the region of the rotating field in the vessel 1 such that it can rotate about the cylinder axis. The rotor is provided with stirring blades 11a, 11b, 12 and comprises permanent magnets 5 co-operating with the rotating field.
