Solubilities of Bis(2,2,6,6-tetramethyl-4-piperidinyl) Maleate in Hexane, Heptane, Octane, m-Xylene, and Tetrahydrofuran from (253.15 to 310.15) K

Abstract

Using the Glew-Hildebrand saturation technique, the solubilities of bis (2,2,6,6-tetramethyl-4-piperidinyl) maleate in hexane, heptane, octane, m-xylene, and tetrahydrofuran at temperatures from 253.15 K to 310.15 K were measured with the help of the classical equilibrium method. The experimental data were correlated with the modified Apelblat equation.

The solubility of mercaptosuccinic acid in water+ (methanol, ethanol, acetone) mixtures from (278.15 to 333.15K)

“…It is widely used in complexometric titrations [6] and fluorescence probes [7] to detect some metal ions. In addition, the sodium salt of the anionic Au(I) complex of mercaptosuccinic acid (Gold sodium thiomalate) is an effective antiarthritic drug [8].…”

Solubilities of norfloxacin in ethanol, 1‐propanol, acetone, and chloroform from 294.15 to 318.15 K

“…On the basis of the assumption used in the inferential process for the modified Apelblat equation that the activity coefficient is invariable during a certain temperature range (Wang et al, 2004), i in Equation (6) can be merged into J . Equation (7) can be obtained from Equation (6) by logarithmic treatment:…”

Solubilities of p-Aminophenol in Sulfuric Acid + Water + (Methanol, Ethanol, 1-Propanol, 2-Propanol, 1,2-Propanediol, and Glycerin, Respectively) from (292.35 to 348.10) K

“…For each mixed solvent system, both the mass fraction of sulfuric acid and the mass fraction of alcohol are 0.20. The temperature dependence of p-aminophenol solubility at fixed solvent composition is described by the modified Apelblat equation: 15,16 where x is the mole fraction of p-aminophenol. T is the absolute temperature, and A, B, and C are the parameters in eq 1.…”
