MARTINEZ COSTA, Brandon Smith. A physicochemical look at the solubility of propane in W-formyl morpholine and sulfolane. Rev. ion [online]. 2022, vol.35, n.2, pp.7-18.  Epub 25-Abr-2023. ISSN 0120-100X.  https://doi.org/10.18273/revion.v35n2-2022001.

Worldwide propane gas or liquefied petroleum gas (LPG) has been widely used for various purposes, such as refrigerant gas, fuel, heating, among others. Propane is a hydrocarbon belonging to the paraffin family, which is considered soluble in some organic substances. The purpose of this reflection is to cover an interpretive and critical study on the solubility of propane in two organic solvents: W-formyl morpholine (NFM) and sulfolane at 298.15, 313.15 and 343.15 K, taking into account the pressure conditions in works completed. This work includes a physicochemical perspective towards the analysis of pressure and temperature as the main quantitative factors in the binary systems propane (2) + NFM (1) and propane (2) + sulfolane (1), highlighting a critical and global analysis about the parameters of the Krichevsky-Ilinskaya equation (KI). Finally, and under the established conditions, the effects of the Peng-Robinson equation (PR) are discussed, such as the binary interaction parameter (BIP), the alpha function and some modifications thereof.
