2) the epoxy ketone is treated with 2-3 equivalents of a hydrazine hydrate in presence of substoichiometric amounts of acetic acid. (wikipedia.org)

In the present work, valence stabilization of divalent iron during gamma irradiation was studied in presence of some organic additives, belonging to some other classes of organic compounds such as Phenol (aromatic alcohol), Acetone (aliphatic ketone), 4-Aminopyridine (heterocyclic amino compound) and Hydrazine hydrate (aliphatic amino compound) to complement our previous studies.

Ammonia5
The production of hydrazine by oxidation of ammonia or urea with hypochlorites is well-known. (sciencemadness.org)
Commonly available solutions of sodium hypochlorite and ammonia are very dilute, meaning that a lot of energy needs to go into concentrating the reaction mixture before isolation of the hydrazine via precipitation of its sulfate, and this concentration stage can be fairly expected to further reduce already-poor yields. (sciencemadness.org)
I found a page that said oxidation of ammonia in the presence of ketones, to form ketazines, and subsequent hydrolysis of ketazines to form hydrazine was one current industrial method. (sciencemadness.org)
Ethanol forms explosive products in reaction with the following compound : ammonia + silver nitrate (forms silver nitride and silver fulminate), iodine + phosphorus (forms ethane iodide), magnesium perchlorate (forms ethyl perchlorate), mercuric nitrate, nitric acid + silver (forms silver fulminate) silver nitrate (forms ethyl nitrate) silver(I) oxide + ammonia or hydrazine (forms silver nitride and silver fulminate), sodium (evolves hydrogen gas). (libertynatural.com)
The hydrazine is produced when there is more Ammonia in the mixture, and that combination is not only toxic, but can also be explosive. (industrysupplyinc.com)
Sulphate2
Why not use Ca(OCl)2, ppte CaSO4 along with the hydrazine sulphate, filter it and then add it to boiling water, and filter out (very nearly all of) the CaSO4, leaving a fairly pure hydrazine sulphate solution. (sciencemadness.org)
In the present work, the protective effect occurring due to the presence of additives belonging to different classes of organic compounds namely, Phenol (aromatic alcohol), Acetone (aliphatic ketone), 4-Aminopyridine (aromatic heterocyclic nitrogen compound) and Hydrazine hydrate (aliphatic amine) on divalent iron ions during extended gamma irradiation, has been studied. (scirp.org)
Derivatives2
A further phenomenon of toxicity common to many hydrazine derivatives is hemolysis and the appearance of Heinz‑Ehrlich inclusion bodies in erythrocytes. (guidelinecentral.com)
HH is used as a reducing agent, an oxygen scavenger in treatment of boiler water, and as a source for drug - hydralazine is an anti-tubercular drug, as well as for agricultural chemicals, and other hydrazine derivatives. (avanschem.com)
Aqueous2
Anhydrous hydrazine, and aqueous solutions, are colourless liquids. (unep.org)
It is an aqueous solution containing 64% of Hydrazine. (avanschem.com)

The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that a sample of ethyl alcohol has a sg of 0.785 then we can calculate that its density is 0.785 x 62.4 = 49 lbs/cu.ft. (simetric.co.uk)
Oxidation1
This is thought to be due to the oxidation of hydrazine to diimide under the conditions employed in the reaction. (wikipedia.org)
Mushrooms2
Likewise, California biochemist Bruce Ames has estimated that we ingest 10,000 times as much natural pesticide (hydrazines in mushrooms, aflatoxins in peanuts) as we do man-made residues, yet no one rides around with a bumper sticker reading NO PEANUTS. (discovermagazine.com)
These mushrooms contain hydrazine toxins, which is often removed by cooking and shouldn't be eaten raw. (vuebangkok.com)
Alcohols2
The Wharton olefin synthesis or the Wharton reaction is a chemical reaction that involves the reduction of α,β-epoxy ketones using hydrazine to give allylic alcohols. (wikipedia.org)
The molecular structure of these substances contains alcohol and amine functional groups, and has the chemical properties of alcohols and amines, making them in many Synthetic applications have shown very useful coordination properties with the formation of a cool acid reaction, which reacts with hydrazine to form a guanamine-based compound.

Reacts1
However, it is still impure to begin with, subject to degradation in storage, and it reacts with sulfuric acid to form low-solubity CaSO4, which would contaminate precipitated hydrazine sulfate. (sciencemadness.org)

The mild elevation of transaminases seen in as many as 20% of patients who are treated during the first 2 months of therapy may reflect direct toxicity from hydrazine metabolites, which can covalently bind to cellular macromolecules, including DNA. (medscape.com)

Aliphatic1
The Wharton reaction also commonly suffers from reduction of the allylic alcohol product down to the aliphatic alcohol. (wikipedia.org)
Sodium1
Household bleach contains sodium hypochlorite, and when this is mixed with ethanol or isopropanol that is in common rubbing alcohol, the reaction produces chloroform. (industrysupplyinc.com)
Glycerin1
Glycolic extracts were obtained by macerating the leaves of C. pachystachya in grain alcohol and glycerin or propylene glycol. (bvsalud.org)
Sulfate1
I could just order hydrazine sulfate, but where's the challenge in that, I ask you? (sciencemadness.org)
Reaction3
This reaction occurs rapidly at room temperature with the evolution of nitrogen and the formation of an allylic alcohol. (wikipedia.org)
The mechanism of the Wharton reaction begins with reaction of the ketone (1) with hydrazine to form a hydrazone (2). (wikipedia.org)
When you mix both of these you get a reaction that forms chloramine vapors that may lead to poisonous hydrazine. (industrysupplyinc.com)
Ketone1
The Wharton olefin synthesis allows the transformation of an α,β unsaturated ketone into an allylic alcohol. (wikipedia.org)
Salts1
Hydrazine is a reducing agent so one needs to keep it away from metal salts, especially copper alloys to avoid potential fires. (yarchive.net)
Oxidizer2
Since trichloroisocyanuric acid (TCCA, also known by a variety of other names) is a relatively mild, safe, and readily obtained oxidizer (again, from swimming pool chemicals), I've been wondering lately if it could be used in place of the troublesome hypochlorites for hydrazine preparation. (sciencemadness.org)

Pure2
I'm not quite sure about the mechanism of this experiment, but it is unlikely that pure hydrazine detonated. (yarchive.net)
We developed a ternary N2H4/AN/H2O graph on which we were able to shade in the area of composition which was detonable, and it did not include any compositions near that of pure hydrazine. (yarchive.net)
