几种新型叠氮增塑剂的热力学特性研究
Study on Thermodynamic Properties of Several Innovative Azide Plasticizers
摘要
Abstract
To study the effects of molecular structure and composition on the thermodynamic properties of azide plasticizer,several innovative azide plasticizers with similar molecular structure were designed.The specific heat capacities of the plastici-zers were measured by using micro DSC.The combustion heats of plasticizers were measured by oxygen-bomb calorimeter,and the standard molar enthalpies of formation were calculated.The gun propellant formulations with different plasticizers were designed,and their energetic properties were calculated by means of internal energy method.The results show that the specific heat capacities increase with increasing the main chain and the number of functional groups in the side chain.The combustion heat increases with an increase in carbon content and a decrease in the carbon-hydrogen ratio.The standard molar enthalpy of formation increases with an increase in nitrogen content.1,5-diazido-3-oxapentane (AZDEGDN) and 1-azido acetoxy-2,2-az-ido methyl-3-azido propane (TAMPAA) have high positive heats of formation,which are 585 kJ/mol and 1212 kJ/mol,re-spectively.The force constant of AZDEGDN-based propellant is higher by 5J/g than that of DIANP-based propellant,while the flame temperature is decrased by 128 K.The force constant of TAMPAA-based propellant is higher by 20J/g than that of DI-ANP-based propellant,and the flame temperature is increased by 36 K.关键词
