Reactions with Oxygen, Ozone, and Nitrogen

OF2 mixes homogeneously with equimolar amounts of O2 at 90 K or O3 at 77 K without reaction [1]. Mixtures of liquefied O3 and O2, which are not completely miscible at -183°C or below, are stabilized by addition of OF2 to form a single liquid phase at -183°C. From the 03 02 0F2 phase diagram the minimum amount of OF2 required is about 8% when there is about 45% O3 in the O3-O2-OF2 solution [2]. 

The photolysis of OF2-O2 mixtures in an inert matrix at 4 K yielding O2F is described [6]. The production of OF2 during the photolysis of OF2 in 02 suggests an exchange mechanism involving O2F2 [6] according to 

Investigations of the thermolysis of OF2 between 770 and 1390 K by shock waves yielded for the equilibrium reaction 0F2 + 0 20F the Arrhenius parameters A = 10 cm mor s Eg=10.0 kcal/mol (forward reaction) and A=10 ° , Ea=16.0 (reverse reaction) [7]. From flow experiments k 10 cm -mol s (forward reaction) was estimated [10]. 

and FNO2 [4]. From flow experiments a rate constant k reaction of OF2 with N atoms was estimated [10].
