Physical and thermodynamic properties of trifluoromethane

(p, ρ, T) measurements on trifluoromethane in the supercritical region at temperatures from 310 K to 350 K

“…(1-4) Hori et al (2) measured (p, r, T ) by the constantvolume method with a 99.1 mass per cent pure sample and reported that their results agreed with those by Hou and Martin (1) within a pressure deviation of about 0.003·p. Aizpiri et al (4) reported that their isotherms of the (p, r, T ) measurements extrapolated quite smoothly to the coexistence curve by Hori et al Ohgaki et al.…”

“…(1,2,4) The results are given in table 3 with the literature values and their deviations from the present results. The pressures measured by Hori et al, (2) those by Aizpiri et al, (4) and those by Hou and Martin, (1) are larger than the present results by 0.0018·p to 0.0037·p, by 0.0053·p to 0.020·p, and by 0.0063·p, respectively. The pressure difference between the Density deviations of the present (p, r, T ) measurements given in table 1 from an equation of state proposed by Platzer et al (11) are shown in figure 2.…”

Preparation and characterization of simvastatin nanoparticles using rapid expansion of supercritical solution (RESS) with trifluoromethane

“…Simvastatin is poorly soluble in supercritical carbon dioxide (Mole fraction solubility = 2.00×10 −6 to 5.35×10 −4 for temperatures 308-348 K and pressures 121.6-354.6 bar) [39]; therefore trifluoromethane which is a good solvent for the drug ( Table 2) due to its ability to form hydrogen bond with the ester group in simvastatin chemical structure, was selected as the SCF [40][41][42].…”
