A METHOD FOR A COMPLEX UTILIZATION OF NITRATE OXIDIZERS OF LIQUID ROCKET FUEL (LRF) WITH SIMULTANEOUS OBTAINING POLYNITROCOMPOUNDS AND SOME NITRATE SALTS OF HYDRAZINE DERIVATIVES

摘要

A method for a complex utilization of nitrate oxidizers of liquid rocket fuel (LRF) with simultaneous obtaining polynitrocompounds and some nitrate salts of hydrazine derivatives involves rectification of nitric acid solutions and nitrogen oxides containing hydrofluor and orthophosphoric acid (without withdrawal or with preliminary withdrawal of H3PO4 and HF) with obtaining aqueous solution of nitric acid with admixtures of orthophosphoric acid and conditioned nitroleum or 90-95 % HNO3. Iodine-containing mélanges and amyl are subjected to reprocessing, during rectification obtained is 90-99,5 % of HNO3, being used for synthesis of polynitrocompounds of the class A from compounds A1 at t = -10...-100 DEGREE C during 10-10000 min.
