Abstract
Presented is a method for Batch or continuous production of nitrogen trifluoride (NF) using direct fluorination of organic solution of trimethylsilylamines at low temperatures. Fluorine gas reacts with a solution of tris(trimethylsilyl)amine or bis(trimethylsilyl)amine in a suitable reactor to produce NFin a continuous flow process. The crude product can be purified by a channeling the crude process flow through a scrubber to remove reactive byproducts and by cryogenic trapping of other non reactive byproducts in the process flow. Temperatures in the reaction and storage vessels are maintained to control the reaction products based on thermodynamics of the process and products. NFis liquefiable at −126 degree Centigrade, and may be collected and used in other processes. The method also produce NFas a continuous gas flow process where fluorine is channeled to contact micro droplet suspensions of bis(trimethylsilyl)amines in sulfur hexafluoride.
