    • The invention relates to non-organic chemistry, in particular to the production of nitrogen fluorides NF3, tetrafluoohydrasine N2F4, difluorodiazine N2F2 and difluoroamine NF2H. The inventive method for producing nitrogen fluorides by fluorinating the flux of ammonium hydrogen fluorides having a general formula NH4H (x-1) Fx, where x= 2, 1-3, 0, with gaseous fluor while agitating said flux consists in introducing into the flux agents which bind the obtained hydrogen fluoride and also in dividing and cleaning obtained products. An active circulation of reagents is carried out by an ordered motion of the flux in a vertical direction, the process being performed in relation to the produced fluoride at a temperature ranging from 80 to 153 DEG C. Said method makes it possible, by improving the agitation of reagents and determining certain parameters of the reaction, to modify the composition of obtained products, predominantly produce one of said products, increase the production of target products and ensure safety of the process.
    • 本发明涉及非有机化学,特别涉及氮氟化物NF3,四氟二氢氮自由基N2F4,二氟二氮嗪N2F2和二氟胺NF2H的生产。 本发明的制造氮氟化物的方法是通过在搅拌所述助熔剂的同时氟化具有通式为NH 4 H(x-1)F x的氟化氢铵,其中x = 2,1-3, 助熔剂,其结合所得的氟化氢,以及分离和清洁获得的产物。 试剂的活性循环通过助熔剂在垂直方向的有序运动进行,该方法相对于所产生的氟化物在80至153℃的温度下进行。所述方法使得可以通过改进 搅拌试剂并确定反应的某些参数,改变所得产品的组成,主要生产所述产品之一,增加目标产品的生产并确保工艺的安全性。
