“…The results show that methanol had the best desorption of TBBPA from Fe 3 O 4 @MON-NH 2 . The methanol gave larger solubility of TBBPA than those for acetonitrile and isopropanol, resulting in the good desorption of TBBPA from Fe 3 O 4 @MON-NH 2 . In addition, the adsorbed TBBPA can be desorbed using methanol under ultrasonication within 3 min (Figure S8).…”

Development of functional porous materials for efficient elimination of environmental pollutants is of great importance in green chemistry and environmental protection. Here we report the design, synthesis, and application of a core–shell magnetic amino-functionalized microporous organic network nanosphere (Fe3O4@MON-NH2) for efficient magnetic adsorption of a typical brominated flame-retardant tetrabromobisphenol A (TBBPA) from aqueous solution. By integration of the hydrophobic networks and hydrogen binding sites within MON-NH2, the synthesized core–shell Fe3O4@MON-NH2 nanospheres gave good adsorption for TBBPA. The adsorption equilibrium of TBBPA (50 mg L–1) on Fe3O4@MON-NH2 was achieved within 1 min, showing ultrafast adsorption kinetics of Fe3O4@MON-NH2 for TBBPA. The adsorption of TBBPA on Fe3O4@MON-NH2 followed the pseudo-second-order kinetics and Langmuir adsorption models, giving a maximum adsorption capacity of 135.9 mg g–1 at 25 °C. The adsorption of TBBPA on Fe3O4@MON-NH2 was a spontaneous and endothermic process controlled by positive entropy. Encouraged by the large adsorption capacity, rapid adsorption kinetics, and the small effect of pH (5–10), dissolved organic matter, and ionic strength on the adsorption, the application of Fe3O4@MON-NH2 for TBBPA removal in real water samples was achieved. The used Fe3O4@MON-NH2 can be easily regenerated and reused at least four times without significant reduction of the adsorption capacity. These results revealed the potential of Fe3O4@MON-NH2 for adsorption and removal of environmental pollutants from aqueous solution.

“…The thermodynamic properties of mixing play important roles in a non-ideal solution system, which are useful for guiding the optimization of industrial crystallization and production. Based on the Lewis-Randall rule, the thermodynamic changes of mixing can be expressed by , where M E is the excess properties. Δ mix M id represents the thermodynamic properties of mixing in an ideal system.…”

“…The λ h equation was proposed by Buchowski et al and Cui et al, commonly used to correlate the solubility and temperature. in which T m is the melting point, and λ and h are the adjustable parameters. The λ value describes the non-ideality of solution, and the h value is used to calculate the excess enthalpy of solution.…”

In this work, the solid–liquid phase equilibrium of N,N′-diethylthiourea (DETU) was investigated in different solvent systems from both solid-state structure and solution thermodynamics. The single-crystal structure of DETU was determined for the first time, and the intermolecular hydrogen bonding N–H···S interactions are dominant in the crystal packing. The thermodynamic equilibrium solubility was determined by the gravimetric method in 12 solvents (methanol, ethanol, n-propanol, isopropanol, n-butanol, sec-butyl alcohol, n-pentanol, acetone, butanone, methyl acetate, ethyl acetate, and acetonitrile) from 283.15 to 323.15 K. It was found that the solubility in alcohols decreases with increasing the length of the carbon chain and follows the rule of “like dissolves like”, whereas in non-alcohol solvents, the rule does not apply. The experimental data were further correlated by the modified Apelblat equation, λh equation, and NRTL model. All the correlation derivations are lower than 5%, and the NRTL model receives the best fitting performance. Furthermore, the thermodynamic functions of mixing including enthalpy, entropy, and Gibbs energy were derived, and the results expectedly suggest a spontaneous and entropy-driven mixing process. All the crystallographic and thermodynamic data reported in this study will provide the fundamental data for designing and optimizing the crystallization of DETU.

“…AA is a white-like crystalline powder, and its molecular structure is shown in Figure 1. AA is not only an important kind of monomer for the production of nylon-66 [31], but also for the manufacturing of fibers, intermediates of medicine, adhesives, insecticides and dyestuffs, and also an additive for the food industry [32,33]. However, there are some problems in the industrial production of AA, for instance, unpredictable polymorphs, impurity inclusion and maldistribution [34].…”

In this contribution, we experimentally determined the metastable zone width (MSZW) of adipic acid (AA) in different polar solvents to reveal the nucleation behavior. We performed analyses for different cooling rates, saturation temperatures and polar solvents. The findings showed that the MSZW increased as the cooling rate increased, or saturation temperature or polarity decreased. Here, we suggest that the hydrogen bond donor capacity decreases as the polarity of the solvent decreases, which weakens the solute and solvent interaction and makes the desolvation process more difficult during nucleation. Furthermore, we found that the MSZW is mainly determined by the cooling rate, when the cooling rate is large enough. On account of the classical nucleation theory, it was found that the sizes of the critical nucleus and Gibbs nucleation energy do not increase monotonously with increasing driving force. Moreover, this study confirms that solid–liquid interface tension is associated with crystallization driving force.
