The relaxation properties of polymer composites based on latex styrene-alkyl methacrylate polymers and water-soluble 2,3,9,10,16,17,23,24-octa[(3,5-biscarboxy)-phenoxy]phthalocyanine are studied in the temperature range from ?150 to +250°C. Characteristic mechanical loss maxima are observed on the inner friction spectra of unmodified and modified polymers corresponding to various patterns of intermolecular mobility and local and segmental types of intermolecular interactions. The modification of the polymers is accompanied by decreases in their glass-transition temperatures. This effect may be explained by a decrease in the intermolecular interactions of copolymer units in the presence of phthalocyanine. 相似文献

Interphase distribution of micro amounts of ReO 4 ? between aqueous solutions of mineral acids and solutions of phosphoryl-containing mono-, di-, and tripodands, derived from 1-(methoxydiphenylphosphoryl)-2-diphenylphosphorylbenzene in dichloroethane was studied. The stoichiometry of extracted complexes was determined, the effect of HNO3, HCl, and H2SO4 concentration in aqueous phase and the nature of organic solvent on the efficiency of transition of ions into organic phase was considered. The growth of the number of phosphoryl groups in podand molecule enhances its extraction ability toward Re(VII). The possibility of selective recovery and preconcentration of Re(VII) with complexing sorbent obtained by noncovalent binding of phosphoryl-containing podand on the surface of macroporous polymer Amberlite XAD7HP was shown. 相似文献

The synthesis of 1,5-bis(2-dihydroxyphosphoryl-4-ethylphenoxy)-3-oxapentane [(HO)2(O)P(C6H3CH2CH3)(OCH2CH2)2O(C6H3CH2CH3)P(O)(OH)2] (H4K2) and single crystal X-ray diffraction study of H4K2 · 2H2O (I) are described. The crystals are orthorhombic, a = 33.291(4) Å, b = 8.9374(10) Å, c = 8.1021(9) Å, V = 2410.6(5) Å3, Z = 4, space group Cmc21, R = 0.0484 for 2566 reflections with I > 2σ(I). In I, the molecules of H4K2 are hydrogen-bonded to two crystallographically independent H2O molecules to give neutral conglomerates H4K2 · 2H2O. The electroanalytical characteristics of poly(vinyl chloride) membranes based on H4K2 were tested. Cu2+ and Zn2+ complexes with H4K2 and Er3+, Nd3+, and complexes with H4K2, 1,5-bis[2-(dihydroxyphosphoryl-4-methoxy)phenoxy]-3-oxapentane, 1,5-bis[2-(dihydroxyphosphinyl)phenoxy]-3-oxapentane, and 1,8-bis[2-(dihydroxyphosphinyl)phenoxy]-3,6-dioxaoctane were prepared. 相似文献

Octa(benzo-15-crown-5)-substituted phthalocyanine and its complexes with d-metals (NiII, CoII, CuII, ZnII, and CdII) have been synthesized for the first time. The compounds were studied by UV—Vis spectroscopy, MALDI-TOF mass spectrometry,
NMR, ESR, IR spectroscopy, and Raman spectroscopy. The dependence of the spectral characteristics of the studied compounds
on the ion radius of the complexing agent was demonstrated.

First calculation of molecular parameters (MP) of new octa-(benzo-15-crown-5)-substituted phthalocyanine derivatives and of its metallo complexes Zn(II), Ni(II) (Ib, Ic) is carried out. A prediction was made of the possible formation therefrom of metaphases, and for that purpose the synthesis of these compounds and investigation of their mesomorphic properties was performed. For compounds Ia-Ic the formation of high-temperature enantiotropic mesophases was established typical for discotic mesogenes, in good agreement with the prediction. Proceeding from the data on miscibility of 2,3,9,10,16,17,23,24-octa-[(4′-benzo-15-crown-5)-oxy]-phthalocyanine Ia with discotic mesogene 2,3,6,7,10,11-hexa(cyclohexanebenzoyloxy)triphenylene (II) displaying nematic mesomorphism the compound Ia was assigned to the group of nematic mesogenes and by the texture of the mixture to discotic mesogenes forming columnar type nematic phase (N Col). Convergence of the results of prediction and experimental data is about 83%. 相似文献

The distribution of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Sc between aqueous solutions of their salts and solutions of 2-phosphorylphenoxy acid amides in dichloroethane containing an ionic liquid (1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide) have been studied. Metal ion extraction has been found to increase considerably in the presence of this ionic liquid in the organic phase. The stoichiometries of extractable complexes have been determined. The influence of aqueous HNO3 concentration and of the nature of extractant and ionic liquid on the efficiency of REE(III) and scandium(III) recovery to the organic phase has been considered. 相似文献
