“…In the last years, several studies have been focused on the study of the solubility of naturally occurring hydroxybenzoic acids. Since 2007, Noubigh and collaborators have presented some studies on the solubility of gallic, protocatechuic, syringic and vanillic acids in water and organic solvents [2][3][4][5][6][7][8][9]. Additionally, there were also contributions from other researchers that studied salicylic [10][11][12][13][14][15], gallic [13,[16][17][18][19], protocatechuic [20,21], syringic [20], veratric [22] and vanillic acids [23,24].…”

The solubilities of gallic, protocatechuic, gentisic or α-resorcylic acids were measured in nine pure solvents (water, methanol, ethanol, 1-propanol, 2-propanol, 2-butanone, ethyl acetate, acetonitrile and dimethylformamide) at 298.15 K and 313.15 K, using the analytical isothermal shake-flask method. Additionally, solid phase studies of the selected phenolic acids were carried out using differential scanning calorimetry (DSC) and X-ray diffraction (XRD), giving access to important data on melting properties as well as on the structure of the solid phase before and after the dissolution. The NRTL-SAC model coupled to the reference solvent approach (RSA) were applied to correlate the solubility data in a set of seven solvents and, after used to predict the solubility in 1-propanol and dimethylformamide. Average relative deviations (ARD) between 28 and 40% for the correlation and between 16 and 59% for the predictions were obtained. These values are within the order of magnitude usually found for such type of semipredictive models, using a limited set of data.

“…The solubility of EES in different pure solvents was determined by using the gravimetric method [14][15][16][17]. The temperature was controlled by a thermostat bath (Julabo CF41, Germany) with uncertainty of ± 0.01 K. All samples were dried in a vacuum oven at 318.15 K until the total weight didn't change over time.…”
