Process for nitrogen trifluoride synthesis |
| abstract |
The present invention is directed to a method for the synthesis of nitrogen trifluoride from elemental fluorine gas and a source of ammonia in a gas-liquid phase reaction comprising; 3F2 + NH4H(x-1)Fx → NF3 + (3+x) HFwherein the melt ratio HF/NH<sub>3</sub> represented by x in the above formula is at least 2.55 and the reaction liquid is agitated or mixed with a mixing apparatus with power input to the mixing apparatus at a high level equivalent to or greater than 1000 watts per cubic meter. This improved synthesis method allows for enhanced nitrogen trifluoride yields of 70% or greater. |
