Chemical properties edit

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]

Synthesis and reactions edit

It can be produced by the reaction of dichlorine monoxide and dinitrogen pentoxide at 0 °C:[2]

Cl2O + N2O5 → 2 ClONO2

or by the reaction:[3]

ClF + HNO3 → HF + ClONO2

It can also react with alkenes:

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

Chlorine nitrate reacts with metal chlorides:[4]

4 ClONO2 + TiCl4 → Ti(NO3)4 + 4 Cl2
