Enthalpies of solution and crystallization of fumaric acid in aqueous solution

Solubility of Fumaric Acid in Propan-2-ol, Ethanol, Acetone, Propan-1-ol, and Water

“…The measured solubility of fumaric acid from (279 to 352) K is listed in Table and graphically plotted in Figure . To verify the uncertainty of the measurement, the solubility of fumaric acid in water in this work was measured and compared with the literature data . Compared with the literature data, the relative deviation of the solubility was lower than 0.05. x 1 is the experimental solubility, and x 1 calcd is the calculated solubility in Table .…”

“…Fumaric acid [CAS No.110-17-8] ( trans -butenedioic acid) is a dicarboxylic acid and is one of the most important acidulent agents in the food industry . In addition, fumaric acid has important practical applications in the polymer industry and in medicine, in particular as antifungicides and as a counterion for salt formation…”

Measurement of cation binding to immobilized vanillin by isothermal calorimetry

“…All calorimetric determinations were performed in a SETARAM C80 mixing calorimeter [21,22] capable of maintaining a baseline of ±0.12 µW with a temperature stability of ±0.0001 • C. The experiments were carried out at 298.15 K with aqueous cation solutions at pH 6.0 (controlled using HCl/NaOH solutions). Samples of approximately 100 mg of Sil-Van (without solvent) were put into the lower part of the mixing cell closed by a circular membrane of Teflon.…”

Interaction of Ag(I), Hg(II), and Cu(II) with 1,2-ethanedithiol immobilized on chitosan: Thermochemical data from isothermal calorimetry

“…All calorimetric determinations were performed in a SE-TARAM C80 mixing calorimeter [36,37], capable of maintaining a baseline of ±0.12 µW with a temperature stability of ±0.0001 • C. The experiments were carried out at 298.15 K with aqueous cation solutions at pH 6. Samples of approximately 50 mg of QTDT were put into the lower part of the mixing cell closed by a circular PTFE membrane.…”
