Description

A practical set-up for the study of chemistry which involves the reaction of a gas-liquid or a liquid-solid heterogeneous system. The agitator permits gas introduced through side arm of the bearing to enter the hollow agitator shaft and pass into the reaction system underneath the disc which supports the 4 blades. With agitator running between 800-1600rpm, a very fine dispersion of gas-liquid is obtained. The catalytic hydrogenation of aromatic nitri derivatives with platinum, palladium, or Raney-nickel catalyst are an excellent example.
