Hydrazine is a man-made chemical and is not found in natural waters. The determination of hydrazine is usually made on boiler feedwaters, process waters, and other waters that have been treated with hydrazine (N 2 H 4) for the purpose of maintaining residuals to prevent corrosion by dissolved reducing chemical reacts with dissolved oxygen to form nitrogen and water.

Hydrazines (H₂NNH₂) are clear, colorless liquids with an ammonia-like odor. Hydrazines are highly reactive and easily catch fire. Workers may be harmed from exposure to hydrazine. The level of harm depends upon the dose, duration, and work being done. Hydrazine sulfate is soluble in water but practically insoluble in eth-anol. Both compounds are thermally unstable (Akron ). Physi-cal and chemical properties of hydrazine and hydrazine sulfate are listed in the following table.

There are two types of hydrazine: anhydrous hydrazine (N2H4) and hydrazine hydrate (N2H4・H2O). Hydrazine hydrate is mainly used as a raw material for plastic foaming agents, with 28% of hydrazine used in water treatment and pH control.

Four biowaste resistojet designs and two hydrazine augmen- ters are analyzed and numerical results compared for recommenda- tions of designs for performance and qualitatively for reliability to give guidance to future resistojet designs. STUDY MODELS The following study models were used to define the concepts.

The results of the study are to be used in the technology development program of the biowaste resistojet system and for demonstration test planning by the. novel design for a man-tended platform and the design and integration of a resistojet propulsion system.
These man. tended space platforms will be serviced initially by the Shuttle Orbiter and at a later date from the Space Station. This paper pre- sents the design of one such man-tended platform,File Size: 3MB.
Numerical and experimental study of a 1-kW hydrazine engineering design model arcjet thruster with simulated hydrazine reaction products as propellant was performed.
A two-dimensional numerical model incorporating the effects of viscous dissipation, Lorentz force, ohmic heating, heat conduction, radiation loss, and pressure work was developed.

Hydrazine occurs as a colorless, oily, flammable liquid that is miscible with water. (6,8) Hydrazine has a penetrating odor, resembling that of ammonia, with an odor threshold of ppm.

A series of propellant compatibility tests has been conducted, and the results are presented. Generally, on the basis of mass loss, there were no compatibility problems. Biowaste resistojets, for which water was a candidate propellant, were baselined on the hydrazine.
The Ref. 3 study considered the cost of propellant launch, estimated at about $/kg, and the cost of ground bed design could be suitable for resistojet applications, but some means of automatic.
HYDRAZINE Hydrazine is the simplest diamine in its class of compounds and may be thought of as derived from ammonia by replacement of a hydrogen atom by the – NH 2 group. The hydrated hydrazine, N 2H 4.H 2O was first prepared by Curtius in The anhydrous hydrazine as a water free base was prepared by De Bruyn for the first Size: KB.
