Abstract

LA PRESENTE INVENCION ESTA DIRIGIDA A UN METODO PARA LA SINTESIS DE TRIFLUORURO DE NITROGENO A PARTIR DE UN GAS DE FLUOR ELEMENTAL Y UNA FUENTE DE AMONIACO EN UNA REACCION DE FASE DE GAS-LIQUIDO QUE COMPRENDE; 3F{SUB,2}+ NH{SUB,4}H{SUB,(()X-1()F{SUB,X}--> NF{SUB,3} + (()3+X())HF EN DONDE LA PROPORCION DE FUSION DE HF/NH{SUB,3} REPRESENTADA POR X EN LA FORMULA ANTERIOR ES AL MENOS 2,55 Y EL LIQUIDO DE REACCION ES AGITADO O MEZCLADO CON UN APARATO DE MEZCLA CON ENTRADA DE CORRIENTE EN EL APARATO DE MEZCLA A UN ALTO NIVEL EQUIVALENTE O SUPERIOR A 1000 WATIOS POR METRO CUBICO. ESTE METODO DE SINTESIS MEJORADO PERMITE PRODUCCIONES MEJORADAS DE TRIFLUORURO DE NITROGENO DEL 70% O SUPERIORES.
