A practical set-up for the study of chemistry which involves the reaction of a gas-liquid ora liquid-solid heterogeneous system.
The agitator is constructed to permit gas introducedthrough side arm of the bearing to enter the hollow agitator shaft and pass into the reactionsystem underneath the disc which supports the four blades. With the agitator running between800-1600 rpm, a very fine dispersion of gas-liquid is obtained.
The catalytic hydrogenationof aromatic nitro derivatives with platinum, palladium or Raney-nickel catalyst serves as anexcellent example. Center joint on flask is 45/50, center joint on head is 19/38. All othersare 14/20. Thermometer not included. Condenser uses 3/8-inch or 5/16-inch I.D. tubing, size Chose connection.
