Solubility of Benzoic Acid in Pure Solvents and Binary Mixtures

Abstract

The solubility of benzoic acid has been determined in ethanol, toluene, heptane, cyclohexane, pentane, and chloroform and in binary mixtures of ethanol + heptane and ethanol + toluene, in the temperature range of (278.15 to 323.15) K. The solubility is high in ethanol, reasonably high in chloroform, lower in toluene, and quite low in the remaining three pure solvents. In the binary mixtures the solubility of benzoic acid increases with increasing concentration of ethanol. The solubility of benzoic acid increases with increasing temperature.

Solubility determination and thermodynamic models for dehydroepiandrosterone acetate in mixed solvents of (ethyl acetate + methanol), (ethyl acetate + ethanol) and (ethyl acetate + isopropanol)

“…Fig. 1 and Table 2 show that the experimental solubility values agree very well with those in the literature [23,24,26], and the largest value of the relative deviation is 6.30%. The agreement with published data suggests that the experimental method is reliable.…”

“…1, and they are tabulated in Table 2 together with the relative deviations of our determined solubility with the values taken from the Refs. [23][24][25][26]. Fig.…”

“…The experimental results together with the data in the literature [23][24][25][26] are shown graphically in Fig. 1, and they are tabulated in Table 2 together with the relative deviations of our determined solubility with the values taken from the Refs.…”

“…RD 1 %, RD 2 %, RD 3 % and RD 4 % are the relative deviations of our determined solubility with the data taken from the Refs. [23][24][25][26], respectively. RD = x e Àx lit x lit , where x e and x lit denote the mole fraction solubility determined in this work and taken from literatures, respectively.…”

Revealing the Roles of Desolvation and Molecular Self-Assembly in Crystal Nucleation from Solution: Benzoic and p-Aminobenzoic Acids

“…For each chosen supersaturation 120 mL of stock solution was made by dissolving the appropriate amount of PABA in the respective solvents (for toluene / benzoic acid this was reduced to 50mL). Solubility data for and polymorphs has been reported previously (13,16,18,19) but were re-measured in this work at 20°C for each solvent using a gravimetric method (five repeats).…”
