Solid–Liquid and Solid–Liquid–Liquid Equilibria in the KI+H₂O+i-C₃H₇OH Ternary System within 10–120°C

Production of High-Purity Allyl Alcohol by the Salting-Out Method from Formic Acid-Mediated Deoxydehydration of Glycerol

“…The recovery ratio of organic species ( R ) is an important index to evaluate salting-out efficiency in salting-out process, which is often related to the type of salts and mass fraction of salts in the system. − Herein, the recovery ratio of allyl alcohol were calculated by the mass of allyl alcohol in organic phase after addition of salting-out agents and the initial mass of allyl alcohol in aqueous solution. As shown in Figure , the recovery ratio of allyl alcohol can be significantly improved by enhancing the mass faction of KH 2 PO 4 or K 2 CO 3 , the sequence of recovery ratio was R (K 2 CO 3 ) > R (KH 2 PO 4 ) > R (NaCl) at a certain salting-out factor.…”

Solubility, Phase Equilibria, and Critical Phenomena in the Ternary KBr + H2O + C5H5N System from T = 283.15 to 363.15 K

“…Phase equilibria in mixtures of the components of the ternary KBr + H 2 O + C 5 H 5 N system were studied by the visual polythermal method 24 from T = 283.15 to 363.15 K. The experimental procedure is described in detail elsewhere. 1,2 Mixtures of the three components were prepared by weighing on an analytical balance with an accuracy of ±1 × 10 −4 g in 6 mL thermostable glass vials so that their compositions were changed in several selected sections of the concentration triangle. The ampoules with the mixtures were sealed and placed alternately into a U-10 ultrathermostat.…”

“…On the introduction of salting-out agents, the binary water + organic solvent system, not delaminating in the entire temperature range of its liquid state, behaves as if it has a low-lying upper critical point and/or a high-lying lower critical point. 1,2 Such systems include the water + pyridine system. 3 Pyridine and its aqueous solutions are used in the production of dyes, medicines, and insecticides, as well as solvents for inorganic and organic substances.…”

“…We , discussed the effect of salts on the mutual solubility of components, the composition and temperature of the solution corresponding to the critical point of liquid–liquid equilibrium when introduced into a binary liquid system characterized by an upper or lower critical solution temperature (UCST or LCST), or not delaminated throughout the whole temperature range of their liquid state. On the introduction of salting-out agents, the binary water + organic solvent system, not delaminating in the entire temperature range of its liquid state, behaves as if it has a low-lying upper critical point and/or a high-lying lower critical point. , Such systems include the water + pyridine system …”

Phase Equilibria in the Ternary System “Potassium Iodide – Water – Tert-Butyl Alcohol” within 5–30°C

“…Для определения температуры критической ноды монотектического равновесия и в дальнейшем состава критической точки был осуществлен выбор I сечения, как описано в [11], которое характеризовалось переменным содержанием третичного бутилового спирта и постоянным соотношением масс иодида калия и воды 62:38 мас. % соответственно.…”
