Solubility and density of the disodium salt hemiheptahydrate of ceftriaxone in (acetone+water) at K

Measurement and correlation of solubilities of apigenin and apigenin 7-O-rhamnosylglucoside in seven solvents at different temperatures

“…High-performance liquid chromatography was used to determine the solubilities of apigenin and apigenin 7-O-rhamnosylglucoside because the solubilities of these two compounds in selected solvents in this work were too small to be measured by using the gravimetrical method [10]. To prove the reliability of the experimental method, the known amounts of apigenin and apigenin 7-Orhamnosylglucoside were completely dissolved in methanol at T = 298.2 K. The concentrations of solutions were measured by HPLC.…”

Measurement and correlation of solubility of trans-resveratrol in 11 solvents at T= (278.2, 288.2, 298.2, 308.2, and 318.2) K

“…In continuation of our studies on the solubilities of drug or natural products in solvents [10,11], the solubilities of trans-resveratrol in methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 1-pentanol, 1-hexanol, ethyl acetate, tetrahydrofuran, acetone, and water (pH 6.0) were measured by HPLC analytical method at T = (278.2, 288.2, 298.2, 308.2, and 318.2) K. The experimental data were correlated using a thermodynamic equation.…”

Solubility of 2-(2,4,6-Trichlorophenoxy)ethyl Bromide in Methanol, Ethanol, Propanol, Isopropanol, Acetonitrile,n-Heptane, and Acetone

“…The normal melting temperature, T m , can be substituted for the triple point temperature, T t . With these substitutions, eq can be rewritten as: ln ( normalγ x x ) = normalΔ fus H R T normalm ( 1 − T normalm T ) …”
