摘　　要：以生物法1,2,4-丁三醇(BT)和甘油为原料,经硝化反应合成了硝化甘油(NG)/1,2,4-丁三醇三硝酸酯(BTTN)。通过理论计算和实验分析了杂质对NG/BTTN安全性能的影响。结果表明,木质素四硝酸酯等硝酸酯的键离解能和分解反应的活化能均低于NG的键离解能和分解反应的活化能,降低了NG/BTTN的安全性能。通过化学反应提纯了生物法BT,制备的NG/BTTN的阿贝尔安定性试验达到合格标准。该方法提纯的生物法BT有望未来用于NEPE(硝酸酯增塑聚醚)固体推进剂和炸药。Using the biosynthetic 1,2,4-butanetriol(BT)and glycerin as raw materials,the nitroglycerin(NG)/1,2,4-butanetriol trinitrate(BTTN)was synthesized by the nitrification reaction.The influence of the impurities on the safety performance of NG/BTTN was analyzed by the theoretical calculation and experiment.The results show that the bond dissociation energy and activation energy of decomposition reaction of nitrates such as lignin tetranitrate are lower than those of NG,the safety performance of NG/BTTN was reduced.The biosynthetic BT was purified by using chemical reaction.The Abel stability test of the prepared NG/BTTN achieved the qualified standard.The biosynthetic BT purified by using this method is expected to be used in NEPE(nitrate ester plasticized polyether)solid propellant and explosive in the future.
