The discovery,study,and implementation of the Co-and Mn-catalyzed hydrohydrazination and hydroazidation reactions of olefins are reported.These reactions are equivalent to direct hydroaminations of C-C double bonds with protected hydrazines or hydrazoic acid but are based on a different concept ...
PURPOSE:To obtain hydrazines, with simplified process, without necessitating the liquid separation procedure after the reaction, by treating a hydrazing salt of a specific cation exchange resin with a base or an acid, thereby eliminating the hydrazine from the resin. CONSTITUTION:A benzophenonazine...
The Raschig method is used in the commercial manufacturing of hydrazine, in which NaOCl mixture is reacted with excess NH3.which subsequently yields the final NH2 NH2 product along with HCl acid. NH3+NaOCl→HCl+NH2NH2NH3+NaOCl→HCl+NH2NH2 It may also be made similarly by reacting NH2 CONH2...
While they're unloading the G-boat, I wish you'd get the tanks refilled with hydrazine and nitric acid. FromProject Gutenberg "If we had a franchise, we could force Space Fuels to sell us hydrazine," said Deveet unhappily. FromProject Gutenberg ...
. The product is then cooled to 0 °C and H2SO4 added in amount to react with the hydrazine to form hydrazine sulfate, N2H6SO4, insoluble solid. Hydrazine hemisulfate, (N2H5)2SO4, is soluble in H2O. It can also be made by the reaction of NH3 and hydroxylamine-O-sulfonic acid....

(175mL) is a clear liquid which contains ~40-45% of N2H4. Note that hydrazine attacks glass, rubber and cork, and stainless steel equipment should be used. The percentage of hydrazine is determined by titration with standard acid (methyl orange indicator) or against standard iodine (starch ...
