Oxidation with nitrogen tetroxide

To obtain the modified ANP, the chemical pretreatment can be carried out, for instance by means of the selective oxidation with nitrogen tetroxide. The oxycel-lulose was prepared by the following method (Kumar, 2003) the starting cotton cellulose (100 g) was soaked with mixture of 85 wt% o-phosphoric and 70 wt% nitric acids (2 1), and after addition of 20 g of sodium nitrite the reaction system was kept at room temperature for 48 h. 

The oxidation of (S)-( + )-methylphenyl-n-propylphosphine with nitrogen tetroxide led to retention of configuration with considerable racemization, whereas oxidation with nitric acid gave the oxide with inversion of configuration. ... 

MMH fuel is generally used with nitrogen tetroxide (N204) oxidizer in small spacecraft rocket engines such as orbital maneuvering or altitude control engines. Compared to... 

Chlorine (I) nitrate is formed by the reaction of chlorine-(IV) oxide or chlorine(I) oxide with nitrogen(V) oxide or dinitrogen tetroxide. All reactions proceed in trichloro-fluoromethane or l,l,2-trichloro-l,2,2-trifluoroethane solvent, in the molten state, or in the gas phase. The best method has proved to be the preparation involving nitro-...

The 4-nitro-3-pyrazolin-5-ones are listed in Table XXVIII. They have been prepared most frequently by direct nitration of 3-pyrazolin-5-ones, usually with concentrated nitric acid.807,809,880,888,1001,1320 The oxidation of 4-nitroso-3-pyrazolin-5-ones to give the 4-nitro compounds has been mentioned in connection with reactions of the 4-nitroso compounds. Nitration of 3-pyrazolin-5-ones with nitrogen tetroxide has been accomplished.1491... 

PERCHLOR (127-18-4) Decomposes slowly on contact with water or moisture, forming trichloroacetic acid and hydrochloric acid. Violent reaction with concentrated nitric acid (produces carbon dioxide), strong oxidizers, strong alkalis, powdered, chemicallyactive metals such as aluminum, barium, beryllium, lithium, and zinc. Incompatible with nitrogen tetroxide, finely divided metals. Decomposes in UV light, on contact with red- hot metals, and in...
