METHOD OF TREATMENT OF INDUSTRIAL EQUIPMENT FROM ASYMMETRIC DIMETHYLHYDRAZINE RESIDUE Russian patent published in 1999 - IPC

Abstract RU 2140905 C1

FIELD: chemical technology. SUBSTANCE: invention relates to methods of rocket fuel components processing. Method involves treatment of equipment with carbon-containing compound - wetted carbon dioxide followed by the addition of halide alkyl of the general formula C_nH_2n+1Hal where n = 1-6; Hal is Cl, Br, J at mole ratio of halide alkyl to asymmetric dimethylhydrazine = (1.1-30): 1 to the formed an aqueous solution of dimethylcarbazic acid dimethylhydrazine salt. EFFECT: decreased negative effect of asymmetric dimethylhydrazine on an environment and attendants, decreased cost of processing. 2 cl, 1 dwg, 7 ex
