As the molecular ion has an odd mass, it must contain an odd number of nitrogen atoms. With one nitrogen, the residual mass 57 can be ascribed to F3 the presence of one nitrogen is confirmed by the intensity ratio 53/52 the formula that is proposed, NF3 (nitrogen trifluoride), is confirmed by the interpretation of the peaks that are observed.

Catalytic polymerization was performed in the presence of a designed composite catalytic system containing boron trifluoride-anisole complex and metaphosphoric acid for benzonitrile under a nitrogen atomosphere. The reaction temperature was lowered to about 200 C and the polymer obtained was linear and soluble, without any trace of cyclic trimers, a by-product described in the literature. But the molecular weight was in the range 1400-1700, with no obvious variation under different polymerization conditions. 

Mixtures containing NF3 and H2 are explosive in the range 9.4 to 95 mol% NF3. The explosion hazard is reduced by diluting the mixture with a gas such as N2, Ar, or He [4]. Nitrogen trifluoride-n-butane mixtures with 25 to 98.5 mol% NF3 explode violently when sparked. The ranges of flammability for methane, ethane, and propane can be anticipated to lie between those of hydrogen and butane. Mixtures of nitrogen trifluoride and 26 to 52 mol% perfluoroethane burn, but do not explode when sparked [3]. 

With water, nitrogen trifluoride forms a clathrate hydrate when ice at -25 to -40°C is exposed to pressurized NF3 (9 to 23 atm). Hydrate formation was found complete within 24 h by the fall of gas pressure. X-ray analysis indicated the clathrate hydrate to be of structure 1, space group Pm3n. The dielectric behavior and the F NMR spectrum of that hydrate as well of others containing tetrahydrofuran, p-dioxane, or sulfur hexafluoride as additional hosts, were analyzed to study the site distribution and motional dynamics of NF3 [1 ]. A crystalline clathrate... 

Leaks of nitrogen trifluoride in process lines or equipment may be detected by applying soap solution to the suspected area. Leaks will be indicated by bubble formation. Leaks on the cylinder or cylinder valve area can be detected in the same manner. If a leaking cylinder is found, move the cylinder to a well-ventilated area and contact the manufacturer. Proper safety precautions should be followed, especially for other than minor leaks, which will require the use of personal protective equipment, including self-contained breathing apparatus. 

In Group 15 (V), nitrogen compounds readily form molecular compounds with BF. Phosphoms compounds also form adducts with BF. Inorganic or organic compounds containing oxygen form many adducts with boron trifluoride, whereas sulfur and selenium have been reported to form only a few (41—43).
