Apparatus IPK (enlarged picture)
The isoperibolic reaction calorimeter was specially developed for investigation of polymerisation reactions. Because of the specific design of this calorimeter the results are independent of possible polymeric coating of the reactor wall and changes of the viscosity of the chemical mixture during the reaction.
The experimental setup of the isoperibolic calorimeter is as follows:
The calorimeter is used in the isoperibolic operation mode only, that means the jacket temperature is constant. The isoperibolic mode corresponds to the majority of processes in the chemical industry.
The reaction can be run in the batch or semi batch mode. Changes of the experimental parameters are possible, e.g. feed rate, process temperature, pressure or type and frequency of the stirrer.
