Using a Cailletet apparatus, bubble points in the binary systems of carbon dioxide with methylcyclohexane and tetrahydropyran, were measured. The temperature ranges from 263 up to 353K, and pressures from 0.4 up to 11.5MPa were applied. The experimental results were modeled using the predictive Soave-Redlich-Kwong and Universal-Quasi-Chemical (PSRK/UNIQUAC) method. The lacking binary interaction parameters of the UNIQUAC model were evaluated and reported. The average absolute deviations between the experimental and predicted bubble point pressures are 1.53 and 1.72% for the carbon dioxide + methylcyclohexane and the carbon dioxide + tetrahydropyran systems, respectively.
