Solubility of Benzene in Water.
TLDR
In this paper, the authors used ultraviolet spectrophotometry to determine the mutual solubility of benzene in water and showed that it can be demonstrated and proved by a redetermination of the relationship.Abstract:
F o r the determination of individual mass transfer coeff ic ients for the benzene-water system, the mutual solubility of the components is required. T h i s paper dea ls with the solubility of benzene in water. T h e interpretation by Seidell (23) of the then-available portion of the present (1, 3-5, 7-19, 21-23, 25, 26) data on the solubility of benzene in water indicated a relationship that continually increased with temperature in a manner similar t o h i s other interpretations on the solubility of hydrocarbons in water. T h e more recent data of Bohon and Claussen (4) were the first to indicate a minimurn in the solubility curve for benzene (and other aromatic compounds), although Hill (13) suspected one. Taken a s a whole, the avai lable data might have been considered discordant. As a precise analytical technique for the analysis of benzene in water was needed for mass transfer s tudies , it was decided t o demonstrate and prove the technique by a redetermination of the solubility relationship. Ultraviolet spectrophotometry was selected a s the analytical tool. Study and experience indicated that the analytical technique had to b e developed with great care to avoid errors due to excess ive volatility, such as found by Saylor, Stuckey, and Gross (22), to improper calibration, to temperature-induced hazes , and perhaps to wall adsorption effects.read more

Rigorous Phase Equilibrium Calculation Methods for Strong Electrolyte Solutions: The Isothermal Flash
TL;DR: In this article , a new approach is proposed and is rigorously derived by treating phase equilibrium as a minimization problem of the Gibbs free energy, while utilizing the electroneutrality condition as a constraint.

Indirect Determination of Hydroxyl Radicals in Fine Particle Mist Generated from an Odor Control Technology via HPLC
TL;DR: The indirect detection and determination of hydroxyl radicals generated by their reaction with benzene to produce phenol was performed through UV-Vis spectrophotometry (UV-Vis) and high performance liquid chromatography (HPLC) as mentioned in this paper.
