7789-26-6 Usage
Uses
Used in Rocket Propellant Industry:
Nitryl hypofluorite is used as an oxidizing agent in rocket propellants for its strong oxidizing properties. This application takes advantage of its ability to enhance the combustion process and improve the performance of rocket engines.
As an oxidizer, nitryl hypofluorite plays a crucial role in the functioning of rocket propellants, ensuring efficient and powerful thrust during space missions and other aerospace applications. Its use in this industry is due to its high reactivity and ability to significantly increase the energy output of the propellant mixture.
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.

Reactions of chlorine fluorides and oxyfluorides with the nitrate anion and alkali-metal fluoride catalyzed decomposition of ClF5
Christe, Karl O.,Wilson, William W.,Wilson, Richard D.
, p. 675 - 677 (2008/10/08)
The binary chlorine fluorides ClF5, ClF3, and ClF, when used in an excess, all undergo facile fluorine-oxygen exchange reactions with the nitrate anion, forming FClO2, unstable FClO, and ClONO2, respectively, as the primary products. Whereas FClO3 does not react with LiNO3 at temperatures as high as 75°C, FClO2 readily reacts with either LiNO3 or N2O5 to give ClONO2 and O2 in high yield, probably via the formation of an unstable O2ClONO2 intermediate. With an excess of ClF, chlorine nitrate undergoes a slow reaction to give FNO2 and Cl2O as the primary products, followed by Cl2O reacting with ClF to give Cl2, ClF, and FClO2. The alkali-metal fluorides CsF, RbF, and KF catalyze the decomposition of ClF5 to ClF3 and F2, which can result in the generation of substantial F2 pressures at temperatures as low as 25°C.
