Synthesis and Characterization of Nickel and Zinc Sulfide Ethylenediamine Complexes
In the present work, nickel and zinc sulfides ethylendiamine (N2H4C2H4) complexes were prepared in an autoclave at 180 C for 12 h. Transmission electron microscope (TEM) and X-ray powder diffraction were used to study the morphology of the two samples. The infrared absorption spectra were obtained and discussed in the range (200-4000 cm). New bands appeared at about 238,240 and 297 cm assigned ...
متن کاملDifferential Pulse Anodic Stripping Voltammetric Study of Zinc- Ethylenediamine Complex
Differential pulse anodic stripping voltammetric study of zinc-ethylenediamine complex has been investigated using thin mercury film coated glassy carbon electrode at 30°C. The overall work was carried out at constant ionic strength (I = 0.20 mol dm -3 ) and pH (9.10±0.10). The electrode processes were found to be reversible and diffusion controlled. The results revealed that zinc forms three (...
متن کاملHyperfine Structure and Tunneling Motion in Ethylenediamine
The first investigation of the microwave spectrum of ethylenediamine (NH CH –CH NH ) showed that in the gas phase this molecule occurs in two conformers which both exhibit a large amplitude tunneling motion corresponding to an interchange of the roles of the amino groups. In conformer I, the tunneling splitting is about 172 MHz while it is only 2.7 MHz in conformer II. In the paper an analysis ...
متن کاملAllergy to the ethylenediamine component of aminophylline.
Intravenous aminophylline is used as a first line treatment for bronchial asthma. This preparation consists of theophylline or a salt of theophylline dissolved in a solution of ethylenediamine, which confers greater solubility and reduces the alkalinity of the drug.1 In clinical usage side effects of tachycardia, seizures and nausea are well known. We report on the much less common, but clinica...
متن کاملThe Effect of Theophylline with Ethylenediamine
Cheyne-Stokes respiration, found associated with cardiac failure, has been attributed to cerebral anoxia (1) on the basis of decreased cerebral blood flow, which is depressed in proportion to the decrease in cardiac output (2). Since Aminophylline increases cardiac output (3) and at the same time arrests Cheyne-Stokes respiration (4), it seems logical to conclude that the latter response occurs...
