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-difluoroaminopropane 1,2and 2,2-DP and 1,2-bisdifluoroamino-2-methyl propane IBA the decomposition of 1,3-bis difluoroaminopropane 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.
