Phase equilibria in layering systems of water, polyethyleneglycol ethers of monoethanolamides of synthetic fatty acids (SFAs) (synthamide-5), and ammonium chloride are studied. The possibility of using such systems for the liquid extraction of metal ions is evaluated. The effect the nature of salting-out agents has on the processes of segregation of the systems has been considered. 相似文献

A new solvothermal method has been developed for preparing nanocrystalline titania powders by reacting titanium isopropoxide with acetic acid. The photocatalytic activity of a sample prepared at 250°C is shown to far exceed the activity of a commercially available sample. 相似文献

For the first time solubility at 25 and 50°C is studied in the CaCl2 + Mg(NO3)2 ↔ Ca(NO3)2 + MgCl2-H2O four-component reciprocal water-salt system in order to determine the feasibility of preparing calcium nitrate and magnesium
chloride.

The scientific basis of the development of liquid cleaning compositions is physicochemical analysis of multicomponent systems that comprise the major components of detergents. The method was implemented in Optimum software for the sulfirol-8–isobutanol–turpentine–water four-component system. After solubility in the system was studied, homogeneous mixtures were optimized by their physicochemical and functional properties (viscosity, density, refractive index, pH, detergency, and corrosion activity). The compositions having the highest detergency and neutral pH and not causing corrosion on titanium and aluminum alloys were selected and recommended for use as technical detergents. 相似文献

The solubility of p-n-hexyloxy- and p-n-heptyloxybenzoic acids in nonaqueous solvents of different polarities was determined over the temperature range from ?20 to 60°C. Acid polymorphs were obtained by crystallization from solutions and melts and by the thermal shock method. The temperatures and enthalpies of phase transitions and X-ray characteristics of the new polymorphs were determined. 相似文献

A method has been developed for nanoparticles synthesis based on oligomers of sulfobutyl ether β-cyclodextrin (SBE-β-CD) and their structure has been studied by FTIR spectroscopy. The physicochemical properties of “guest?host” inclusion complexes formed by SBE-β-CD and its oligomers with moxifloxacin have been investigated. It has been shown that, as compared with SBE-β-CD, the synthesized oligomers have an increased affinity for moxifloxacin: the dissociation constants for the complexes of monomeric and oligomeric SBE-β-CD are (1.0 ± 0.3) × 10?4 and nearly 5 × 10?6 M, respectively. The binding efficiency increases due to the multy-point interaction of a moxifloxacin molecule with functional groups of the oligomeric carrier. SBE-β-CD oligomers are promising carriers for drugs, in particular, fluoroquinolone-based antibacterial agents, and may be used for the development of new compositions with improved solubility, bioavailability, and prolonged drug release. 相似文献
