Liquid Cp – The Forgotten Benefit Of SIMULAR

Reaction calorimetry allows the heat generated during synthesis to be measured and with SIMULAR this is made
as simple as possible for the user and even on-line figure is supplied without any user input. An important use of
the total heat is the prediction of the maximum temperature that could be reached if this heat were to be released
without any cooling in place.
This temperature, also called the MTSR (maximum temperature of synthesis reaction) is given by the equation:
MTSR (°C) = Treaction + [Total heat released (J/g)/ Cp (J/g °C)]
This requires a value for the specific heat (Cp) of the reacting mixture which can be obtained experimentally in only a
few minutes, by ramping the product temperature by ~2 °C. Then, knowing the amount of heat necessary to do this,
the value of Cp can be calculated.

Based on this simple test, Cp is readily calculated and hence also the MTSR from the equation stated above.
The Cp obtained in this way agrees with literature values to within 5-10% and so is good enough for most
engineering calculations.
