![عکس صفحه اول مقاله: Ternary solubility of mono- and di-tert-butyl ethers of glycerol in supercritical carbon dioxide Ternary solubility of mono- and di-tert-butyl ethers of glycerol in supercritical carbon dioxide](/preview/png/231314.png)
Using a continuous flow apparatus, the ternary solubility of mono- and di-tert-butyl ethers of glycerol (MTBG and DTBG, respectively) in supercritical carbon dioxide was measured at the temperatures of 313.15, 333.15, and 348.15 K; a pressure range of 80–200 bar; and an expanded gas flow rate of 180 ± 10 mL min−1 at average laboratory temperature of 300.15 K and pressure of 0.89 bar. The ternary solubility of the ethers at the constant temperatures of 333.15 and 348.15 K increased with increasing pressure up to the crossover point (i.e., 152 bar for MTBG and 170 bar for DTBG). MTBG exhibited a higher solubility than DTBG in scCO2. The experimental data for the ternary solubility of MTBG and DTBG were correlated using the Bartle equation.
