The plasticizer energetics comprising a eutectic mixture of bis (2,2 - dinitropropyl) type, 2,2 dinitropropyl - 2,2 - dinitrobutylformal and bis (2,2 - dinitrobutyl) type, and its method of preparation

摘要

The invention relates to an energetic plasticizer consisting of bis (2,2 - dinitropropyl) type, 2, 2 - dinitropropyl - 2, 2 - dinitrobutylformal and of the bis (2, 2 - dinitrobutyl) type in a molar ratio of 20 to 68% / 28 to 50% / 4 to 30% and a process for its preparation, which comprises the dissolution of 2, 2 - dinitropropanol and 2, 2 - dinitrobutanol in an organic solvent to form an organic solution in which the molar ratio of 2, 2 - dinitropropanol at 2, 2 - dinitrobutanol is 3: 1 - 6: 1, the addition to the organic solution of a solution of sulfuric acid, in which a source of formaldehyde has been dissolved, while the temperature of the reaction mixture is maintained at less than 20degrec, and the separation and purification of the product from the reaction mixture.
