Solubility of Carbon Monoxide and Hydrogen in Dodecane and 1,4-Dioxane

Solubility of hydrogen and carbon monoxide in dodecane and 1,4-dioxane were
measured using the high pressure solubility cell over thetemperature range from 303
to 323 K and pressure range from 2 to 10 bar. The measured solubility were
correlated and interpreted by activity coefficient models based on regular solution
theory (RST) with Yen andMcKetta correction for polar solvent. Experimental data
and RST shows hydrogen gas and carbon monoxide gas are more soluble in 1, 4-
dioxane than dodecane and carbon monoxide gases have greater solubility towards
both solvents than hydrogen gases. RST model acting in this particular system with
large errors. The RST model might notbe suitable for this particular system.
