VAPOUR PRESSURE: The constants below for Antoine vapour pressure equation were obtained from Richardson and Coulson. The equation is as shown as:

In VP (Vapour Pressure) = Ant A -

Ant B(T+Ant C)

Where vapour pressure is in mmHg, T is the temperature in Kelvin, Ant A, Ant B and Ant C are

constants for the Antoine equation.

P = vapour pressure (mmHg), (A, B, C) = Antoine’s Coefficients, T = temperature (K), mmHg x

133.32 = N/m2

CP= CpVAPA + (CpVAPB)T + (CpVAPC)T2 + (CpVAPD)T3.

Gas Heat Capacities:

Can be calculated by the Ideal gas heat capacity equation:

(Cp = A + BT + CT2 + DT3) or (Cp = a + bT + cT2 + dT3)

(A, B, C, D) = Constants in the ideal gas heat capacity equation, Several group contribution methods have been developed for the estimation of the constants (a, b, c, d), such as that by Rihani and Doraiswamy (1965) for organic compounds.
