Solubility of Gases in Normal-alkanes

Abstract

Solubilities of a number of gaseous were determined in members of the n-pentane n-hexadecane series. Relationships between gas solubilities and physico-chemical properties of members of the series were studied. It was found that gas solubilities varied linearly in the function of reciprocal parachor values of the solvents, and the slopes of the lines were proportional to the sizes and mean polarizabilities of the gases dissolved. An equation was derived solubilities of apolar and moderately polar gases in n-alkanes. The equation is not applicable for polar gases, because the interactions between the gas and liquid molecules cannot be neglected in such cases.
