10036-47-2 Usage
General Description
A colorless toxic irritant gas. Nonflammable. Prolonged exposure of the container to high heat may cause Dinitrogen tetrafluoride to rupture violently and rocket. Used in organic synthesis and as an oxidizing agent in fuel for rockets.
Reactivity Profile
Dinitrogen tetrafluoride is an oxidizing agent. Explodes or ignites on contact with reducing agents at normal temperatures, including alcohols, amines, ammonia, beryllium alkyls, boranes, dicyanogen, hydrazines, hydrocarbons, hydrogen, nitroalkanes, powdered metals, silanes, or thiols [Bretherick 1979 p.174]. Can explode at high temperatures. Can explode with shock or blast when under pressure. Emits highly toxic fumes of fluorine and oxides of nitrogen when heated to decomposition. Several grams of a crude mixture containing Dinitrogen tetrafluoride and nitrogen trifluoride had been allowed to collect in a stainless steel cylinder. During opening of valves to check the pressure, the cylinder exploded, killing one man and injuring another [MCA Case History 683 1966].
Health Hazard
TOXIC; may be fatal if inhaled or absorbed through skin. Vapors may be irritating. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.
Fire Hazard
Some may burn but none ignite readily. Vapors from liquefied gas are initially heavier than air and spread along ground. Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.
Safety Profile
A poison. An unstable explosive gas sensitive to light, heat, or contact with air or steel. At high pressures it can explode due to shock or blast. Flammable when exposed to heat or flame. Potentially explosive reaction with hydrocarbons; hydrogen; organic materials; reducing agents; oxygen. Forms explosive mixtures with alkenyl nitrates; nitrogen trifluoride. When heated to decomposition it emits highly toxic fumes of Fand NOx. See also FLUORIDES, HYDROFLUORIC ACID, and HYDRAZINE.
Check Digit Verification of cas no
The CAS Registry Mumber 10036-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,3 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 10036-47:
(7*1)+(6*0)+(5*0)+(4*3)+(3*6)+(2*4)+(1*7)=52
52 % 10 = 2
So 10036-47-2 is a valid CAS Registry Number.

Modification of an NF3 film by sub-excitation electrons
Tegeder, Petra,Illenberger, Eugen
, p. 401 - 406 (2001)
By applying the IRAS technique (infrared-absorption-reflection spectroscopy) and electron stimulated desorption (ESD) of negative ions we demonstrate that a 10 monolayer (ML) film of NF3 is degraded in the course of low-energy electron irradiation in the range 0-5 eV which is far below the electronic excitation of NF3. Degradation is accompanied by the desorption of F- fragment ions from the film and formation of NF2 radicals and N2F4 molecules in the film. The energy dependence of the degradation cross-section follows that for resonant (dissociative) electron attachment in the low-energy region (≈0-5eV) and increases above 6 eV. We therefore identify (dissociative) electron capture at low energy as the only initial reaction responsible for the chemical changes in the NF3 film.

Condensed phases of difluoramine and its alkali-metal fluoride adducts
Christe, Karl O.,Wilson, Richard D.
, p. 920 - 925 (2008/10/08)
Infrared and Raman spectra of HNF2 and DNF2 in the liquid and the solid phases show that the compounds are associated through hydrogen bridges between the nitrogen atoms. Raman spectra of the KF, RbF, and CsF adducts and infrared spectra of the RbF adduct of difluoramine are interpreted in terms of strongly hydrogen-bridged [F?HNF2]- anions. For the CsF and RbF adducts evidence was obtained for the existence of a distinct second modification of the [F?HNF2]- anion with a significantly stronger hydrogen bridge. The reactions of KF·HNF2 with TeF5OF, OF2, FONO2, and FOClO3 were studied and resulted in the fluorination of HNF2 to HF and N2F4.
