Measurement and correlation of densities and viscosities of 11α-hydroxy-16α,17α-epoxyprogesterone in chloroform

The densities and viscosities of 11α-hydroxy-16α,17α-epoxyprogesterone (HEPG) in chloroform were determined from 287.65 to 321.15 K. The viscosities were correlated using the Vogel-Tamman-Fulcher (VTF) equation, a good accuracy of the correlation being obtained.

Correlation and comparison for solubility of pimelic acid in different solvents

Based on the solubilities of pimelic acid in ether or tetrahydrofuran or ethanol or methanol, the experimental data were correlated and compared with Apelblat equation, simplified Apelblat equation and λh equation, respectively. The results showed that the simplified Apelblat equation had better agreement with experimental data.

Correlation equations for solubility of NaHS in water and organic solvents at 297–323 K

The solubility of NaHS in different solvents had been determined from 297.85 to 342.55 K by an analytical method. A solubility model is proposed and the solubilities calculated by the model show good agreement with experimental data. It provided the basic data for the synthesis of isopropyl mercaptan in industry.

The temperature dependence of pimelic acid solubility in 1-isopropyl-3-methylimidazolium bromide at 295–338 K

The solubilities of pimelic acid in ionic liquid 1-isopropyl-3-methylimidazolium bromide ([i-PMIM]Br) are determined with the suitable experimental method and apparatus. The experimental data of solubilities are correlated with the exponential function equation. The solubilities correlated by the model show good agreement with experimental data.

Density and viscosity of 16α,17α-epoxyprogesterone solutions in chloroform

Abstractdensity and viscosity of 16α,17α-epoxyprogesterone solutions in chloroform were determined over the concentration range up to ∼1.9 mol l−1 at temperatures from 287.65 to 321.15 K. The relative viscosity data were correlated using the extended Jones-Dole equation, a good accuracy of the correlation being obtained.
