Instructions:

This calculator that allows you to find the minimum pressure required to keep the solvent liquid when using our FlowSyn™ unit.

Simply choose your solvent and enter your desired working temperature. If your solvent is not listed choose 'Other' and enter in the entropy of vaporization and known boiling point.

Notes:
* Exact entropy of vaporization unknown

** This is a suggested value based upon an estimated calculation of the entropy of vaporization using the boiling point of the solvent at atmospheric pressure (Trouton-Hildebrand-Everett rule) and is intended to be used as a guide only.

Solvent:
Entropy of vaporization (JK-1mol-1):
Boiling point at atmospheric pressure: °C
Desired working temperature: °C
Minimum BPR pressure:

Unit of pressure:
psi bar
Instructions:

(i) Enter a known reaction temperature (Temperature 1) and time (Time 1)

then either:

(ii) Enter a new reaction temperature (Temperature 2) and click “Calculate” to give the corresponding new reaction time (Time 2)

or

(iii) Enter a new reaction time (Time 2) and click "Calculate" to give the required temperature (Temperature 2).

Notes:
Calculations use the Arrhenius equation with a null frequency factor (A) and an Activation Energy (EA) of 50kJ mol-1
