ENERGETIC PLASTICIZER COMPRISING A EUTECTIC MIXTURE OF BIS (2,2-DINITROPROPYL) FORMAL, 2,2 DINITROPROPYL-2,2-DINITROBUTYLFORMAL AND BIS (2,2-DINITROBUTYL) FORMAL, AND PROCESS FOR PREPARING THE SAME

摘要

The invention relates to an energetic plasticizer comprising bis (2,2-dinitropropyl) formal, 2,2-dinitropropyl-2,2-dinitrobutylformal and bis (2,2-dinitrobutyl) formal in a molar ratio of 20 to 68. % / 28 to 50% / 4 to 30% and a process for its preparation which comprises dissolving 2, 2-dinitropropanol and 2,2-dinitrobutanol in an organic solvent to form an organic solution in which the molar ratio from 2, 2-dinitropropanol to 2, 2-dinitrobutanol is 3: 1-6: 1, adding to the organic solution a sulfuric acid solution in which a source of formaldehyde has been dissolved, while the temperature the reaction mixture is kept below 20 ° C, and the separation and purification of the product from the reaction mixture.
