The Influence of Isomeric Effects on High-Pressure Gas Solubility in Liquids

摘要

The purpose of this study is to present the results concerning the isomeric effects on gas solubility. We have studied the solubility of CO_2 and N_2O in a series of organic non-polar solvents: n-hexane, cyclohexane and metyl-cyclopentane by pressure up to 35 bar and temperatures in a range of 0 / 25℃. In all investigated systems we have found remarkable values of gas solubility with specific features that evidence just the isomeric effects. The regular solutions theory was employed as theoretical model for calculation the solubility of gases in the investigated solvents.
