THE SENSITIVITY OF NITROGLYCERIN TO IMPACT

Abstract

Experimental studies are reported on the initiation-deflagration process occurring in nitroglycerin (NG) and nitro-glycerin solutions as a result of impact. The instrumented apparatus used permitted determination of the pressure-time relationships due to the momentum of the impacting weight and to the resulting deflagration. As a result, impact sensitivity testing of liquids is placed on a sounder basis. A gradual decrease in impact sensitivity is observed as desensitizer concentration is increased up to 16% by weight; a more rapid decrease in sensitivity is found beyond this point. bis(2-fluoro-2,2- dinitroethyl) formal (FEFO), a relatively insensitive energetic liquid, did not show any especially desirable desensitizing properties; the impact sensitivity of FEF) itself is about the same as that of NG solutions containing 29% conventional desensitizer.
