7789-26-6 Usage
Chemical Properties
Colorless gas; acrid odor; density 3.554 g/L at 25°C; liquefies at –46°C; density of liquid 1.507 g/mL at –46°C; solidifies at –175°C; reacts with water(forming HF, OF2, HNO3 and O2); also reacts with ethanol, ether and aniline;soluble in acetone.
Uses
Different sources of media describe the Uses of 7789-26-6 differently. You can refer to the following data:
1. Fluorine nitrate is used in rocket propellants as an oxidizing agent.
2. Oxidizing agent in rocket propellants.
3. Fluorine nitrate (FNO3) is a strong oxidizing gas or liquid. In the liquid state it explodes by
shock or friction. It is used as an oxidizer for rocket propellant fuels.
Preparation
Fluorine nitrate may be prepared by the action of fluorine on nitric acid:
F2+HNO3→FNO3+HF
Also, it is produced when nitrogeneous compounds are electrolyzed in hydrofluoric acid.
Hazard
Fluorine nitrate is shock sensitive, especially in liquid state. The liquefied material explodes when shaken vigorously or in contact with alcohol, ether, aniline, or grease (Bretherick’s Handbook of Reactive Chemical Hazards, 5th. Ed., P. Urben (ed.) 1995, pp 1405-6, Oxford, UK: Butterworth-Heinemann). The gas catches fire when mixed with ammonia or hydrogen sulfide.
Safety Profile
Probably a poison irritant to skin,eyes, mucous membranes. A powerful oxidant anddangerous explosive. Explodes on contact with organicmaterials (e.g., alcohol; ether; grease). Ignites on mixingwith ammonia; dinitrogen oxide; and hydrogen sulfide.Whe
Check Digit Verification of cas no
The CAS Registry Mumber 7789-26-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7789-26:
(6*7)+(5*7)+(4*8)+(3*9)+(2*2)+(1*6)=146
146 % 10 = 6
So 7789-26-6 is a valid CAS Registry Number.
InChI:InChI=1/FNO3/c1-5-2(3)4
