“…It allows for obtaining single well-shaped superlattices with optimized and enhanced properties in the case of solvent (like hexane) inducing repulsive interaction potential between nanocrystals. Furthermore, in a general way, the addition of molecules characterized by a high solubility parameter (triphenylphosphine, thiol, oleylamine, or oleic acid) will promote the organization of nanocrystals. − …”

International audienceHere, we show that the residual presence of reaction products markedly influences the growth mode of 3D superlattices made of silver nanocrystals. The silver nanocrystals (5 or 6 nm in diameter) are synthesized via the reduction of a silver triphenylphosphine complex in the presence of thiols. The presence of triphenylphosphine, coming from the decomposition of the silver precursor, is shown to change the superlattice growth mode in hexane from heterogeneous to homogeneous. In toluene, it remains homogeneous. This is in agreement with simulations based on a Flory-type model, which shows that the interaction potential between the silver nanocrystals in the presence of triphenylphosphine changes from repulsive to attractive in hexane and becomes even more attractive in toluene. Ex situ investigation of the different superlattices following solvent evaporation by scanning electron microscopy reveals different morphologies depending on the growth mode. A transition from films to individual hexagonal-shaped superlattices is observed when the growth mode changes from heterogeneous to homogeneous. Direct in situ observations of the 3D superlattice growth by liquid cell transmission electron microscopy follow in real time the formation process and movement of the superlattices in both hexane and toluene solvents

“…Crystallization processes are the critical steps that determine the quality of PCDMPP to provide sufficient purity. So it is very important to know the solubility of PCDMPP as a function of temperature and solvent composition in selected solvents required for the preparation and purification of the product [7]. Moreover, to the best of the authors' present knowledge, the solubility of PCDMPP in solvents has not been reported in the literature.…”

The solubility of phloroglucinol tris(cyclic 2,2-dimethyl-1,3-propanediol phosphate) in methanol, ethanol, acetone, tetrahydrofuran, acetonitrile, 1,4-dioxane, chloroform and dichloromethane was measured by a static analytic method over the temperature range from 288 to 318 K. The modified Apelblat equation and the Buchowski-Ksiazaczak (kh) equation were applied to represent the measurement results. The results show that the two models can satisfactorily reproduce the experimental data. The thermodynamic properties of the solution process, including the Gibbs energy, enthalpy, and entropy were calculated using the van't Hoff equation.

“…Crystallization processes are the critical steps that determine the quality of the product [ 10 ] of omeprazole sulfide to provide sufficient purity for the next reaction. So it is very important to know the solubility of omeprazole sulfide as a function of temperature and solvent composition in selected solvents required for the preparation and purification of the products [ 11 ]. Moreover, no literature study has reported the correlation between the solubility and temperature or the solvent composition.…”

“…Thus, systematic and necessary information on the crystallization of omeprazole sulfide was obtained. For predicting the solubility of a solute in different solvents, several methods have been presented [ 11 , 15 ]. This study used the modified Apelblat equation and the Buchowski–Ksiazaczak λh equation to correlate and predict the solubility of omeprazole sulfide in different solvents.…”

Solubility data were measured for omeprazole sulfide in ethanol, 95 mass-% ethanol, ethyl acetate, isopropanol, methanol, acetone, n-butanol and n-propanol in the temperature range from 280.35 to 319.65 K by employing the gravimetric method. The solubilities increase with temperature and they are in good agreement with the calculated solubility of the modified Apelblat equation and the λh equation. The experimental solubility and correlation equation in this work can be used as essential data and model in the purification process of omeprazole sulfide. The thermodynamic properties of the solution process, including the Gibbs energy, enthalpy, and entropy were calculated using the van’t Hoff equation.
