15 صفحه اولConductivity of Thionyl Chloride-Lithium Tetrachloroaluminate Solutions
The specific conductivity of solutions of LiA1C14 dissolved in SOC12 was determined as a function of composition and temperature. An analytical expression from which the conductivity can be calculated is given as a function of the mole fraction of LiA1C14 and temperature in the ranges from 0 ~ to 0.37~ and from -20 ~ to +70~ respectively. LiAIC14-SOC14 mixtures are used commercially as electrol...

ELECTROCHEMICAL INVESTIGATION OF OCTAETHYL PORPHYRIN IRON(III) CHLORIDE IN THE PRESENCE OF PYRIDINE, IMIDAZOLE AND COLLIDINE: AN APPROACH TO THE ROLE OF PYRIDINE IN THE COUPLED OXIDATION
Cyclic voltammogram and differential pulse polarograph of octaethyl porphyrin iron(III) chloride in dichloromethane was investigated in the presence of pyridine, imidazole and collidine. Values of E1/2 for FeIII/FeII redox reaction were monitored as a function of axial group concentration, and on the basis of these data, an overall oxidation-reduction and ligand addition scheme was formulated. ...
متن کاملC1 Nuclear Quadrupole Interaction in Thionyl Chloride
21 hyperfine multiplets, up to J = 12, have been measured for thionyl chloride (S0C12), by means of microwave spectroscopy in the region 18.0 —26.5 GHz. Nuclear quadrupole coupling constants along the principal axes of inertia were determined to be Xaa ~ ~ 25.004 ± 0.040 MHz, Xbb = 0.009 ± 0.025 MHz and Xce = 25.013 ± 0.031 MHz. Also, coupling constants along the S—CI bond axis (z axis) and two...
