SENSITIVITY FUNDAMENTALS
Abstract
This quarterly report reviews the initial work on the modified JANAF sensitivity test, and the recent results from studies of detonation sensitivity, failure diameter, and decomposition of 1,2- and 2,2-bis-(difluoroamino)propane (1,2and 2,2-DP) and 1,2-bis(difluoroamino)-2-methyl propane (IBA); the decomposition of 1,3-bis (difluoroamino)propane was also studied. The failure diam. and shock sensitivity of 2,2-DP were measured in pb tubes of 1-mm wall thickness and of IBA in tubes of 1.5-mm wall. The failure diam. of 2,2-DP is less than 5 mm. In 9.5 mm I. D. x 2 mm wall cups the sensitivity is 87 = 6 kbars. The diam. in which IBA propagates a detonation lies between 10 and 15 mm in 1.5-mm wall tubes. In 20 mm I. D. x 2 mm wall cups the sensitivity is 75 = 6 kbars. In Pb confinement, the failure diam. of 1,2-DP and 2,2-DP was found to be less than 0.8 mm; that of IBA was 0.8 mm according to the work so far completed. Decomposition of 1,2-DP in methanol is accelerated by HC1 and LiC1 to about the same extent; LiC1O4 also shows catalytic activity;; 1,3-DP decomposes at 176-200 degrees by HF elimination giving a small amount of malononitrile and a major amount of nonvolatile residue.
