Experimental determination of the critical loci for {n-C6H14 or CO2+ alkan-1-ol} mixtures. Evaluation of their critical and subcritical behavior using PC-SAFT EoS

Gas antisolvent fractionation based optical resolution of ibuprofen with enantiopure phenylglycinol

“…is an outlier, with a diastereomeric purity of 0.37 and a very high yield (0.98). Visual observation of the carbon dioxide-methanol-diastereomeric salt system in a view cell unit confirmed that at 10 MPa and 50°C, 3 phases are formed, contrary to results reported in the literature [49]. The presence of the salt probably changes the phase relations.…”

Experimental determination of critical data of multi-component mixtures containing potential gasoline additives 2-butanol by a flow-type apparatus

“…Each critical data were measured three times in this work, the average value of them was recorded as the final critical point. Similar apparatus and experimental produce have also been used in works of Soo [11], Gil [12] and Horstmann [21,22]. The veracity and repeatability of our apparatus has been checked by measuring the critical points of nine pure compounds, twenty-two binary systems and seven ternary systems [19,[23][24][25].…”

“…Wang [4] determined the critical temperatures and pressures of three binary and two ternary mixtures including methanol, 1-propanol, heptane and methyl tert-butyl ether. Gil [12] measured a series of critical properties of nhexane + alkan-1-ol. Morton [13] also reported the critical data for (alkanol + alkane) mixtures, which include secondary or tertiary alcohols and/or branch chain alkanes.…”

Increasing the Prediction Efficiency of Hansen Solubility Parameters in Supercritical Fluids

“…The amount of ethanol that can be added is limited by two factors. On the one hand there is a shift of the critical point to higher temperatures for increasing ethanol concentration [13]. On the other hand, once a larger amount of ethanol is used, it cannot be separated from the product just by lowering the pressure.…”
