Coal and What We Get from It Marscorp has millions tied up in hydrazine interests, and they're more interested in keeping an atomic ship off this run than they are in a monopoly franchise. Atom Drive By the action of hydroxylamine or phenylhydrazine on aldehydes or ketones, condensation occurs between the carbonyl oxygen of the aldehyde or ketone and the amino group of the hydroxylamine or hydrazine. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 1 "Châtelet" to "Chicago" They want us to send them the quality control specification for the hydrazine that was used as fuel in the first launch. If at First You Don't... When an osazone is decomposed by boiling with strong acids, the phenyl hydrazine groups break off, leaving a compound containing both an aldehyde and a ketone group. The Chemistry of Plant Life Two pressurized containers contained hydrazine and nitric acid, which could be released in tiny streams into peanut rocket chambers by a single valve-release. The Trouble with Telstar Space Fuels won't sell us any hydrazine and nitric acid to refill the tanks. Atom Drive After all the chlorine has been passed in, it is necessary to be certain that the mixture is slightly alkaline, since any excess of free chlorine in the solution prevents the formation of hydrazine. Organic Syntheses In order to obtain a pure white hydrazine sulfate as the first precipitate, it is necessary to cool the hydrazine solution thoroughly and filter it twice before the sulfuric acid is added. Organic Syntheses For example, glucose reacts with phenyl hydrazine in acetic acid solution, in two stages. The Chemistry of Plant Life The mother liquor obtained from the crystallized hydrazine sulfate contains a small amount of hydrazine. Organic Syntheses "All your hydrazine's leaked out in the sand." Atom Drive If the crude hydrazine is brown, it is advisable to use a little bone-black. Organic Syntheses This salt, when suspended in ten times its weight of distilled water and treated with hydrogen sulfide, decomposes into copper sulfide and hydrazine sulfate. Organic Syntheses After the copper salt has been filtered off, the solution is concentrated until the hydrazine sulfate crystallizes. Organic Syntheses It is possible for one man, simultaneously evaporating six dishes of the hydrazine mixture, to turn out from 20 to 25 runs in nine hours.
