Discontinuously operated stirred tank reactors are mostly used if the product quantities to be produced are small or the reactions are slow.
CE 310.04 is part of a device series that enables experiments with different reactor types. In conjunction with the supply unit CE 310, it is possible to examine the function and behaviour of a discontinuous stirred tank reactor. The supply unit CE 310 has a heating water circuit as well as all necessary connections, pumps, tanks for reactants and a product tank.
CE 310.04 is mounted onto the supply unit and held by 2 pins in position. Quick-release couplings enable easy connection of the reactor to the supply unit.
The reactants are preheated in the supply unit at the beginning. After that the reactants are delivered into the stirred tank reactor. A stirrer ensures a homogeneous mixture and thus increases the direct contact of the reactants.
In isothermal operation, a chambered bottom in the stirred tank reactor serves as the heat exchanger to examine the influence of the temperature on the reaction.
The conversion in the stirred tank reactor is determined by measuring the conductivity. A combined conductivity/temperature sensor is included in CE 310. Conductivity and temperature are digitally displayed on the switch cabinet of the supply unit. In addition, the measured values can be captured and processed with data acquisition software (included in CE 310).
