“…3. P-x-y diagram for system 2-propanol/CO 2 at 313 K. ( ) Bamberger and Maurer [13] and (᭹) this work. Table 3 Component loadings, measured vapor and liquid volumes, and calculated liquid and vapor phase composition for CO 2 (1) + argon (2) + 2-propanol (3) at 313 K n 1 (mol) n 2 (mol) seems the ratio of reactants can be increased at pressures above the CO 2 + 2-propanol two-phase region.…”

“…The moles in the vapor phase account for 40% of the total moles at the lowest measured pressure and about 20% of the total moles at the highest measured pressure. The vapor-liquid equilibria of the carbon dioxide + 2-propanol binary was measured at 313 K and compared to the literature data of Bamberger and Maurer [13] which was measured by a flow technique. The data from this work are in good agreement, with slightly higher pressures for the high mole fractions of CO 2 as shown in Fig.…”

The chiral separation of citalopram base by supercritical fluid chromatography on a semipreparative Chiralpak AD column was studied with the use of three alcohol-type modifiers (methanol, ethanol, and 2-propanol) with different volume percentages (5, 10, and 15%). The best separation was achieved when 10% 2-propanol was used in the presence of 0.1% diethylamine as additive. Under these conditions, the resolution reached 2.15 and the selectivity was 1.388. In addition, other parameters that affected the retention and separation properties, i.e. temperature, pressure, and density, were studied in detail. At the same pressure, a decrease in the temperature improved the enantioselectivity as the experimental temperature range was below the isoelution temperature. However, the temperature dependence of the retention factor was complicated. As a rule, the retention factor decreased when the temperature increased at the same density. A satisfactory regression of the logarithm of the retention factor versus density and temperature was obtained using a simplified lattice-fluid model. Surprisingly, the relationship between the Henry constant and density can be accurately correlated by using the same quadratic equation.

Propylene carbonate at 298.15 K, stars [6]; isooctane at 298.15 K, triangles [7]; methanol at 298.15 K, circles [8]; acetone at 303 K, squares [9]; Selexol TM at 298.15 K, plus signs. the only input parameter is the vapor pressure of CO 2 at 298.15 K. These independent calculations are the fundamental advantages of using COSMOtherm over other computational tools that use group contribution methods (e.g.…”

“…This process uses a mixture of morpholines such as N-formylmorpholine as well as N-acetylmorpholine, and is a good choice when the natural gas has a larger concentration of CO 2 compared to typical concentrations found in natural gas wells [5]. Table 1 presents a comparison of literature values for the wt% solubility of CO 2 in propylene carbonate [6], isooctane [7], and methanol [8] at 298.15 K and acetone [9] at 303 K as a function of pressure. Table 1 also contains data for the solubility of CO 2 in Selexol TM at 298.15 K determined in this work.…”
