Copper (II) catalyzed oxidation of Hydrazine hydrate by Potassium ferricyanide
Abstract: The kinetics of Cu(II) catalysed oxidation of hydrazine by hexacyanoferrate(III) is studied in acid medium. The stoichiometry of the reaction is 1:1. The first order condition is [N2H5]>[Fe(CN)63- ] is maintained. The order of the reaction is unity with respect to Fe(CN)63-, fractional orders with respect to hydrazine and copper. The reaction is independent of variation of sulphuric acid and ionic strength. A suitable mechanism is proposed for the reaction. …

Survey in Hydrazine and its Preparation, Reactions, and Their Applications
Abstract: This review concerned with hydrazine derivatives; Hydrazine is an important chemical compound used in jet engine and rocket fuel. Therefore, the European Union prohibits its sales to the developing world at 100% concentration and only permits its sales at 20-25% concentration. It is also used in industry to produce chemicals for textiles, agriculture, photographic development materials, and blowing agents used in the manufacture of foam rubber. It is also used …

Synthesis and Anti-Bacterial Activity Profile of Cyclized Diazonium Compounds
Abstract: Synthesis of cyclised diazonium compounds and their in vitro activity against various microorganisms is described. Several primary aromatic amines were diazotised and the resulting diazotised compounds were coupled with active methylene compounds to give hydrazono derivatives. These were cyclized with hydrazine hydrate, phenyl hydrazine, urea and o-phenylene diamine to give pyrazolin-5-one, substituted pyrazolin-5-ones, pyrimidin-di-ones and benzodiazepinone derivatives, respectively. Some hydrazine derivatives were also produced by reduction of diazo compounds with …

Structural and Magnetic Property Studies of Nanocrystalline Co0.8Zn0.2Fe2O4
Abstract: The synthesis of Co0.8Zn0.2Fe2O4 nanoparticles has been achieved by a simple thermal decomposition method from the inorganic precursor, Co0.8Zn0.2Fe2(cin)3(N2H4)4, which was obtained by a novel precipitation method from the corresponding metal salts, cinnamic acid and hydrazine hydrate. The precursor was characterised by hydrazine and metal analyses, infrared spectral analysis and thermo gravimetric analysis. The thermal decomposition of Co0.8Zn0.2Fe2(cin)3(N2H4)4 yielded Co0.8Zn0.2Fe2O4 nanoparticles, which were characterised for their size and structure using …

Use of NMR and Other Spectroscopy Techniques in Heterocyclic Oxadiazole Derivatives Studies: A Review
Abstract: It was possible to create a number of novel symmetrical 2,5-dialkyl-1,3,4-oxadiazoles with substituents including carboxymethylamino, isopropyloxycarbonylmethylamino, and bromine at the terminal positions of the alkyl groups. The multistep process that was devised used hydrazine hydrate, phosphorus oxychloride, and commercially available acid chlorides that varied in alkyl chain length and terminal substituent.Diisopropyliminodiacetate was an easy way to substitute the intermediate bromine-containing 2,5-dialkyl-1,3,4-oxadiazoles. This was followed by hydrolysis in an aqueous methanol …
