Experiments

  • Fundamentals of a saponification reaction
  • Conversion in each reactor depending on
    * Retention time
    * Temperature
    * Concentration

Specification

  • 3 identical stirred tank reactors made of glass connected in series
  • Chambered bottom made of stainless steel as heat exchanger
  • Delivery between stirred tanks via 2 peristaltic pumps
  • Small reactor capacity for less consumption of chemicals
  • Sensor for measuring the conductivity and temperature
  • Display of conductivity and temperature
  • Temperature control in the reactor

Stirred tanks in series are continuous stirred tank reactors that are connected in series, as the name implies. Compared to a single stirred tank reactor, they provide a higher conversion. Stirred tanks in series allow for variable process control because each individual reactor’s temperature and retention duration may be customized. The gadget series that enables research with various reactor types includes the CRE-3307. Stirred tank behavior and operation can be studied sequentially. The apparatus includes a heating water circuit in addition to all required connections, pumps, reactant and product tanks, and tanks for reactants. The reactor may be quickly and easily connected to the supply unit using quick-release connections.
