Abstract
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 °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.
