A method for the joint utilization of nitro-acid oxidizers of liquid rocket fuel (LRF) and hydrazine-containing LRF with obtaining nitrates of polyatomic alcohols, which involves rectifying nitric acid solutions and nitrogen oxides containing hydrofluorine and orthophosphoric acid and, which consists in the regeneration thereof using the method of rectification (without removal or with preliminary removal of ??3??O4 and HF) with obtaining nitric acid aqueous solution with admixtures of orthophosphoric acid and certified nitroleum or 90-95 % of ??N??3,, at that iodine-containing mélanges and amyl are utilized also, nitric acid oxidizers of LRF of AK type are delivered for the rectification, the obtained nitroleum is divided by rectification into liquefied nitrogen oxides (IV), during rectification 90-99,5 % of HNO3, is obtained which is used for nitriding polyatomic alcohols R(OH)x at the temperature of -10-20 DEGREE C during 15-60 minutes at the weight ratio of nitric acid and alcohol being equal to 4.0-7.5, nitration products û nitric acid ethers are filtered, squashed and/or washed with water and furthermore are stabilized by known methods, processed by oxides, hydroxides or metals carbonates.
