| 摘 要： | 为解决传统TATB合成中氯杂质的影响,以间苯三酚为原料,经过五氧化二氮硝化、甲基化和氨气氨化得到TATB,综合收率为92%,用核磁共振光谱、红外光谱和质谱等进行了表征.采用有机溶剂法精制获得高纯度无氯TATB,收率75%.用DSC及TG分析了TATB的热性能,根据Ozawa公式计算出TATB的热分解活化能和指前因子分别为135.28 kJ/mol和2.340×10~9 s~(-1).

| Abstract: | In order to solve the influence of chloride in the traditional synthesis of TATB,taking phoroglucinol as primary material,1,3,5-triamino-2,4,6-trinitrobeneze(TATB) was synthesized by nitration with N_2O_5, methylation and amination,and its structure was identified by NMR,IR and MS. The effect of amination reaction on the yield and thermal decomposition property of TATB was investigated,the total yield of crude TATB was 92%. High-purity TATB was obtained by organic solvent recrystallization with yield of 75%. Thermal properties of TATB was analyzed by DSC and TG,the thermal decompositon activation energy and pre-exponential factor of TATB obtained by Owaza′s equation are E_(TATB)=135.28 kJ/mol,ATATB=2.340×10~9 s~(-1). |
