By comparing the experimental with simulation results and physically inspecting the reactor, improvements can be made on the temperature measuring device (thermometer) and the heat exchange device:
The temperature of the reactor is measured with a thermometer with tubing in an oil bath. A temperature with the latency of the thermometer is obtained (which is off by at least five minutes for both cooling and heating). This would result in a wrong reactor temperature is reading. However a contact thermometer that would be in contact with the reactor can be used to eliminate this latency.
