A METHOD FOR UTILIZATION OF NITRIC ACID OXIDIZERS OF LIQUID ROCKET FUEL WITH OBTAINING SOME AROMATIC POLYNITRO DERIVATIVES AND SOME SALTS BASED ON NITRATED HYDROCARBON MATERIALS

摘要

A method for utilization of nitric acid oxidizers of liquid rocket fuel with obtaining some aromatic polynitro derivatives and some salts based on nitrated hydrocarbon materials involves rectification of oxidizers with obtaining aqueous solution of nitric acid with admixtures of orthophosphoric acid and distillate - nitro-oleum or 90-95 % of HNO3. Iodine-containing melanges are also subjected to reprocessing. The obtained nitro-oleum is divided by repeated rectification into liquefied nitrogen oxides (IV) and 95-99.5 % of HNO3, being used for the nitration of some aromatic compounds with obtaining polynitro derivatives and nitration of oils and lubricants with subsequent obtaining on their basis of polyfunctional additive materials to lubricants and oils. The polynitro derivatives of aromatic compounds are obtained at one or some stages, or with action of nitrating mixture. The nitration of lubricants and/or oils is performed in one or some stages, or with an action of nitrating mixture or action of mixture of H2SO4 and MNO3, or action of a mixture of HNO3 with acetic anhydride or with acetic acid. The nitration products after washing with water are neutralized with organic bases and ammonia. The waste acid after every nitration stage is used at subsequent stages of nitration, and also neutralized with organic base and ammonia.
