摘要

Bis(5‐amino‐1,2,4‐triazol‐3‐yl)methane (BATZM, C 5 H 8 N 8 ) was synthesized and its crystal structure characterized by single‐crystal X‐ray diffraction; it belongs to the space group Fdd 2 (orthorhombic) with Z ?= 8. The structure of BATZM can be described as a V‐shaped molecule with reasonable chemical geometry and no disorder. The specific molar heat capacity ( C p,m ) of BATZM was determined using the continuous C p mode of a microcalorimeter and theoretical calculations, and the C p,m value is 211.19?J?K ?1 mol ?1 at 298.15?K. The relative deviations between the theoretical and experimental values of C p,m , H T – H 298.15K and S T – S 298.15K of BATZM are almost equivalent at each temperature. The detonation velocity ( D ) and detonation pressure ( P ) of BATZM were estimated using the nitrogen equivalent equation according to the experimental density; BATZM has a higher detonation velocity (7954.87?±?3.29?m?s ?1 ) and detonation pressure (25.72?±?0.03?GPa) than TNT.

BATZM的结构可以描述为具有合理化学几何形状和无病症的V形分子。使用微量微量仪的连续C P模式和理论计算的连续C P模式测定BATZM的特定摩尔热容量(C p,M),C p,m值为211.19≤j≤k≤1mol≤1在298.15?k 。 C P,M,H T - H 298.15K和S T - S 298.15K的理论和实验值之间的相对偏差在每个温度下几乎等同于等效。根据实验密度使用氮当量方程估计BATZM的爆轰速度(D)和爆炸压力(P); BATZM具有更高的爆轰速度(7954.87?±3.29?m?s?1)和爆炸压力(25.72?±0.03?GPA)而不是TNT。
