Chlorine nitrate, with chemical formula ClONO2 is an important atmospheric gas present in the stratosphere. It is an important sink of reactive chlorine and nitrogen, and thus its formation and destruction play an important role in the depletion of ozone.{{cite journal |last1=von Clarmann |first1=Thomas |last2=Johansson |first2=Sören |title=Chlorine nitrate in the atmosphere |journal=Atmos.

__TOC__

Chemical properties

It explosively reacts with metals, metal chlorides, alcohols, ethers, and most organic materials. When it is heated to decomposition, it emits toxic fumes of Cl2 and NOx.{{citation needed|date=September 2023}}

Synthesis and reactions

It can be produced by the reaction of dichlorine monoxide and dinitrogen pentoxide at 0 °C:Schmeisser, M.; Ruff, J. K. & Lustig, M. Chlorine(1) Nitrate

Inorganic Syntheses, Wiley-Blackwell, https://doi.org/10.1002/9780470132401.ch34, 1967, 127-130

:Cl2O + N2O5 → 2 ClONO2

or by the reaction:{{Cite journal|last=Schack|first=Carl J.|date=1967-10-01|title=New synthesis of chlorine nitrate|journal=Inorganic Chemistry|volume=6|issue=10|pages=1938–1939|doi=10.1021/ic50056a047|issn=0020-1669}}

:ClF + HNO3 → HF + ClONO2

It can also react with alkenes:

:(CH3)2C=CH2 + ClONO2 → O2NOC(CH3)2CH2Cl

Chlorine nitrate reacts with metal chlorides:{{cite book|title=《无机化学丛书》第六卷:卤素、铜分族、锌分族|pages=P338-341|author=张青莲|isbn=7-03-002238-6|location=北京|publisher=科学出版社|year=1991}}

:4 ClONO2 + TiCl4 → Ti(NO3)4 + 4 Cl2
