An odd–even effect on solubility of dicarboxylic acids in organic solvents

Kinetics, mechanisms and ionic liquids in the uptake of n-butylamine onto low molecular weight dicarboxylic acids

“…Odd-even carbon alternations for diacids have been observed in physical properties such as vapor pressure, [95][96][97] melting point, 92 and solubility. 93,94 One possibility for the increased reactivity of odd carbon diacids is the arrangement and stability of the crystal lattice. The odd carbon diacids adopt a trapezoidal arrangement due to the twisted conformation and torsional strain resulting from packing.…”

“…93 A similar effect was seen in their solubility in organic solvents. 94 Thus, butylamine may be able to disrupt the odd carbon lattices in an analogous manner, resulting in the higher reactivity of the odd carbon diacids. Another contributing factor may be the orientation and thus the availability of the -COOH groups on the surface.…”

Experimental Assessment and Modeling of the Solubility of Malonic Acid in Different Solvents

“…Investigations on the molecular interactions between malonic acid and the solvents should be further carried out. The solubility data of malonic acid in ethanol, acetone, and acetonitrile was compared with the data reported by Daneshfar et al and Zhang et al . The experimentally determined solubility is higher than in the reported data.…”

Abraham model correlations for estimating solute transfer of neutral molecules into anhydrous acetic acid from water and from the gas phase

“…nonelectrolyte solutes, including two polycyclic aromatic hydrocarbons (naphthalene [66] and phenanthrene [73]), four nonsteroidal anti-inflammatory drugs (2-hydroxybenzoic acid [65], naproxen [72], ibuprofen [74], diclofenac [76]) and two other drug molecules (niflumic acid [77] and salicylamide [64]), nine alkanedioic acids (oxalic acid through sebacic acid) [63], and benzoic acid [70] and three substituted benzoic acid derivatives (4-hydroxybenzoic acid [69], 4-methylbenzoic acid [71], and isophthalic acid [79] The experimental log (P or (CS,organic/CS,water)) and log (K or (CS,organic/CS,gas)) values at 298.15 K for solutes dissolved in acetic acid are listed in Table 1. In total there are 68 log (P or …”
