New high pressure VLE data for the ternary mixture CO2 + n-dodecane (nC12) + 3,7-dimethyl-1-octanol (37DM1O) are presented. A static apparatus with online anal. was used to measure phase compositions at 35, 55 and 75°C, and pressures between 68 and 157 bar. In the high-nC12 region the mixture displayed enhanced solubility, presenting as a pinched two phase band and s-shaped liquid phase curves. Relative solubility, an indicator of fractionation sharpness, increased with 37DM1O content and the 75:25 nC12:37DM1O mixture cannot be separated using CO2. RK-ASPEN, SR-POLAR, PR-BM and PC-SAFT models were evaluated for their ability to correlate these data. RK-ASPEN and PC-SAFT models provided the best and worst correlation of equilibrium pressures with resp. percentage average absolute deviations of 3.1% and 8.5%. RK-ASPEN model was impressive in its ability to capture the co-solubility pinch seen for the 75:25 nC12:37DM1O mixture and the resultant s-shaped liquid phase complexity. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Product Details of 106-21-8).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Product Details of 106-21-8
