International Classification:

B01D 336
C07C10902
C07C10914

US Classification:

203 59

Abstract:

The formaldehyde hydrazone of UDMH can be removed from an aqueous solution f UDMH by codistillation with a hydrocarbon or other solvent which is inert to both acidic or basis mediums. The solvent can then be recovered from the hydrazone solution by washing with an acid solution and the solvent can be reused.

International Classification:

C06B 4300

US Classification:

1491094

Abstract:

At least one combustion modifier is incorporated in liquid propellants by ssolving the modifier in at least one solvent such as alkoxypolyethylene glycol ether or a bis(alkoxypolyethylene glycol) formal to form a solution and mixing the resulting solution with the energetic component of the liquid propellant. Similar solutions of combustion modifier are also suitable for use as casting liquids in cast double-base propellants.

International Classification:

G21C 900

US Classification:

376305

Abstract:

A supercritical water oxidation reactor includes a vessel with an interior urface, two cooling sections, a heat exchanger, an oxygenating section, a pump, and a trap. The interior surface of the vessel has a corrosion-resistant, artificial ceramic or diamond-like coating. The artificial diamond coating is thin and crystal-like in structure. The heat exchanger is located between the two cooling sections. The heat exchanger and the two cooling sections surround the exterior of the vessel. The oxygenating section comprises a porous cylindrical baffle positioned within the vessel. The porous baffle transfers oxygen, hydrogen peroxide, or other oxygenating substances to an aqueous hazardous waste introduced into the reactor. In accordance with another aspect of the invention, the oxygenating section includes a shaft having a helical extension. The shaft has a corrosion-resistant, artificial diamond or diamond-like coating on its outer surface.

Inventors:

George W. Nauflett - Oxon Hill MD

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

C07C11100

US Classification:

564109

Abstract:

The invention is an improved process for the production of methylnitramine y nitrating dimethylurea with a mixture of sulfuric acid and nitric acid with subsequent separation of 1,3-dimethyl-1,3-dinitrourea by the use of a suitable solvent with recovery of a dimethyl dinitrourea in organic solvent, with hydrolysis of the dimethyldinitrourea with hot water to yield methylnitramine.

International Classification:

C07C11100

US Classification:

564109

Abstract:

The invention is a process for reacting methylnitramine with formaldehyde a halogenated solvent and reacting the methylnitramine with formaldehyde in the presence of a strong sulfuric acid catalyst at certain specific temperatures to yield a final product having a yield rate of 70% or greater dimethylmethylenedinitraamine.
