Abstract

The explosive tetrazene (1-amino-1(tetrazol-5-yl-diazenyl)guanidine monohydrate) has been actively used in initiating compositions since the beginning of the 20th century, but it has low thermal and hydrolytic stability. As an alternative to tetrazene, it was proposed to use 2-(tetrazol-5-yl-diazenyl)guanidine (MTX-1), which is its more thermally stable derivative. However, a decision on the application of a particular explosive is made primarily based on its explosive properties; for tetrazene and MTX-1, these properties are not well known. The objectives of this study were to determine the detonation velocity and heat of explosion of MTX-1 in comparison with tetrazene and explain the results obtained. Calorimetric measurements were carried out in a modified steel bomb. Samples of MTX-1 and tetrazene (\(\approx\)1 g) were exploded in helium to determine the heat of explosion and the volume of gases. Experimental data on the critical detonation diameter of both substances were obtained. The detonation velocities of MTX-1 and tetrazene were determined by an electromagnetic method.

四氮杂和MTX-1的爆炸特性

摘要

自 20 世纪初以来，爆炸性四氮烯（1-氨基-1（四唑-5-基-二氮烯基）胍一水合物）一直被积极用于引发组合物，但其热稳定性和水解稳定性较低。作为四氮烯的替代品，有人建议使用 2-(四唑-5-基-二氮烯基)胍 (MTX-1)，这是其更热稳定的衍生物。但是，决定是否使用特定炸药主要是根据其爆炸特性；对于四氮烯和 MTX-1，这些特性并不为人所知。本研究的目的是确定 MTX-1 与四氮烯相比的爆速和爆炸热，并解释所获得的结果。在改进的钢弹中进行量热测量。MTX-1 和四氮烯 ( \(\approx\)1 g) 在氦气中爆炸以确定爆炸热和气体体积。获得了两种物质的临界爆轰直径的实验数据。MTX-1 和四氮烯的爆速是通过电磁法测定的。
