“…Furthermore, for the ideal state Δ mix H id = 0, whereas ΔG fus = 0 at the SLE state. 27 All of the remaining thermodynamic functions for the dissolution of solute were evaluated using the following equations: 27 (12) where x i represents the mole fractions of each component at the given temperature. The excess thermodynamic functions are further estimated using the following equations.…”

The solid−liquid phase equilibrium of para-tertbutylbenzoic acid in methanol, ethanol acetic acid, propan-2-ol, hexane, toluene, 1-octanol, para-tert-butyltoluene, methyl 4-tert-butylbenzoate, and binary (methanol + methyl 4-tertbutylbenzoate) mixed solvent have been determined experimentally within the temperature range of 293.15−333.15 K at atmospheric pressure using a static equilibrium method. The solubility of para-tert-butylbenzoic acid increased with the increase in temperature for the pure solvents, while in the case of methanol + methyl 4-tert-butylbenzoate a maximum solubility effect is achieved at 0.6115 solute-free mole fraction of methanol. The experimental solubility data in pure and binary solvent system were correlated by the modified Apelbat equation, the λh (Buchowski) equation, and the NRTL model, among which the modified Apelbat equation provided better agreement than those with the other models. Furthermore, to understand the nature of interactions involved in a solute−solvent system, the dissolution thermodynamic properties, including enthalpy, entropy, and Gibbs free energy, were determined. This experimental data will be an aid for the design and optimization of the separation and purification processes involving para-tert-butylbenzoic acid.

Acetic acid, CH 3 COOH, is a corrosive organic acid having a sharp odor, burning taste, and pernicious blistering properties. It is found in ocean water, oilfield brines, rain, and at trace concentrations in many plant and animal liquids, and has a place in organic processes comparable to sulfuric acid in the mineral chemical industries. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions, usually called vinegar. Uses include the manufacture of vinyl acetate and acetic anhydride. Vinyl acetate is used to make latex emulsion resins for paints and adhesives. Acetic anhydride is used in making cellulose acetate fibers and cellulosic plastics. About half of the world production comes from methanol carbonylation and about one‐third from acetaldehyde oxidation. Glacial acetic acid is dangerous, but its precise toxic dose is not known for humans. Vinegar, on the other hand, which is dilute acetic acid, has been used in foods and beverages since ancient times.
