Resumo:

N-n-Octylaniline in xylene was used for the extraction separation of antimony( III) from hydrochloric acid media. Antimony(III) was extracted quantitatively with 10 mL4%N-n-octylaniline in xylene. It was stripped from the organic phase with 0.5 M ammonia and estimated photometrically by the iodide method. The effect of metal ion, acid, reagent concentration and various foreign ions was investigated. The method affords binary and ternary separation of antimony(III) from tellurium(IV), selenium( IV), lead(II) bismuth(III), tin(IV), germanium(IV), copper(II), gold(III), iron(III) and zinc(II). Th

We designate as "bridge-flipped isomers" those pairs of molecules that differ only in the orientation of a bridge of atoms linking two major molecular fragments: in benzylideneanilines, Ar-CH=N-Ar' vs. Ar-N=CH-Ar'; in phenylhydrazones, Ar-NH-N=CH-Ar' vs. Ar-CH=N-NH-Ar' (Ar = aryl). We use them as a context in which to evaluate the roles of molecular conformation, hydrogen bonding, space-filling requirements, and supramolecular synthons in establishing crystalline isomorphism or non-isomorphism.

Abstract Dielectric, DSC, thermal expansion and preliminary X-ray diffraction studies on (n-C3H7NH3)- SbBr5 are reported. It was found that this crystal undergoes a complex sequence of phase transitions. On cooling: phase I → phase II at 188.7 K (continuous), II → III at 165 K (1st order, ΔS = 26.8 J/mol K), III → IV at 137 K (1st order, 1.6 J/mol K). On heating: IV → III at 154 K, III → II’ at 168 K, II’ → II at 177 K (1st order, 2.8 J/mol K), II → I at 189 K. All 1st order phase transitions are likely due to the motion of the n-C3H7NH3+cations.

In addition, the distribution ratio was also measured for Pu(IV) and Sr(II) with 1.1 M CHADA in n-dodecane. These extractants were synthesized by adopting simple acid, amine coupling reaction with DCC (dicyclohexylcarbodiimide) and DMAP (N,N′-dimethylaminopyridine) as the coupling agent.

Because mesangial cells (MC) are a target and a degradation site for angiotensin II (ANG II), we characterized the degrading enzymes and receptors of ANG IV, a metabolite of ANG II, on these cells. ANG IV was metabolized into its NH2-terminal deleted peptides, ANG II-(4–8), ANG II-(5–8), and ANG II-(6–8) by rat MC. Total protection of ANG IV was obtained only when PC-18, a specific aminopeptidase N (APN) inhibitor, and JFH-27A, a mixed inhibitor of dipeptidylaminopeptidase (DAP) and neutral endopeptidase (NEP), were simultaneously added. In contrast, thiorphan, an NEP inhibitor, was inactive.
