Abstract:

Five new high explosives, all nitramines, were synthesized by means of the Mannich reaction. The condensation of 3,3,3-trinitropropyl amine and trinitroethanol, followed by postnitration, gave N-2,2,2-trinitroethyl-N-3,3,3- trinitropropyl nitramine. The condensation of 2 moles of 3,3,3-trinitropropyl amine with 1 mole of 2,2-dinitro-1,3-propanediol, followed by postnitration, gave 1,1,1,4,6,6,8,11,11,11-decanitro-4,8-diaza-undecane. The condensation of 3, 3,3-trinitropropyl amine with 2,2,4,4-tetranitro-1,5-pentanediol gave N-3,3,3- trinitropropyl-3,3,5,5-tetranitropiperidine. The condensation of 3,3,3- trinitropropyl amine with 2,2-dinitropropanol, followed by postnitration, gave N-3,3,3-trinitropropyl-N-2,2-dinitropropyl nitramine. The condensation of 3,3- dinitrobutyl amine with trinitroethanol, followed by postnitration, gave N3,3- dinitrobutyl-N-2,2,2-trinitroethyl nitramine. The use of the heat of explosion per unit weight was proposed as a criterion of explosive power to supplement the predicted lead-block and ballistic-mortar values. The contribution to the molar heat of explosion and molecular weight was tabulated for a large number of structural groups. The heat of explosion per unit volume was calculated for a number of high explosives and for some structural changes. RDX was desensitized with a 10 coating of a copolymer of 2,2-dinitrobutyl acrylate 90 and 2- nitrobutyl acrylate 10. A method of predicting the crystal density of explosive compounds is under development.
