The standard enthalpy of formation of 1,4-diethynylbenzene experimentally to be 500.6 ± 6.7 kJ/mol. Calculations show that 1,4-diethynylbenzene has a relatively high adiabatic combustion temperature (about 1970 K at a pressure of 5 atm) and very high heat of combustion in oxygen (42 MJ/kg); therefore, 1,4-diethynylbenzene can be used as the basis to develop an effective dispersing agent of solid fuel that provides an adiabatic combustion temperature of up to 2500 K at a heat of combustion far exceeding the values provided by HMX and the other azides of N-heterocycles previously proposed for this purpose.

1,4-二乙炔基苯的热化学和能量特征

实验中1,4-二乙炔基苯的形成标准焓为500.6±6.7 kJ / mol。计算表明,1,4-二乙炔基苯具有较高的绝热燃烧温度(在5 atm的压力下约为1970 K),并且在氧气中燃烧的热量很高(42 MJ / kg)。因此,1,4-二乙炔基苯可以用作开发固体燃料有效分散剂的基础,该分散剂在燃烧热下的绝热燃烧温度最高可达2500 K,远远超过HMX和其他叠氮化物所提供的值。先前为此目的提出了N-杂环。
