Two energetic compounds, erythritol tetranitrocarbamate (ETNC) and pentaerythritol tetranitrocarbamate (PETNC), and their salts, were synthesized in three steps, characterized and compared. All synthesized compounds were characterized by IR, DSC and multinuclear NMR spectroscopy. Four compounds were further investigated by single crystal X‐ray diffraction. All nonmetal salts show extremely low mechanical sensitivity (IS≥30 J; FS≥360 N). The heats of formation were calculated using Gaussian 09, and the detonation performances were calculated using EXPLO 5. Although these nonmetal salts are lower than the neutral compounds ETNC (D: 7960 m s⁻¹, P: 27.4 GPa) and PETNC (D: 7629 m s⁻¹, P: 24.3 GPa), they possess high detonation performances that are better than TNT. Erythritol‐based and corresponding pentaerythritol‐based energetic materials were compared in terms of their thermostability, detonation velocity and detonation pressure. They were also compared in their respective series. ETNC and PETNC and their salts have short preparation steps and are easy to isolate in high yields, and thus have promising potential applications as explosives.

ETNC及其盐与PETNC及其盐的结构-性质关系

通过三个步骤合成了两种高能化合物，赤藓糖醇四硝基氨基甲酸酯（ETNC）和季戊四醇四硝基氨基甲酸酯（PETNC），并对其特征进行了比较。所有合成的化合物均通过IR，DSC和多核NMR光谱进行表征。通过单晶X射线衍射进一步研究了四种化合物。所有非金属盐均显示出极低的机械敏感性（IS≥30J；FS≥360N）。形成热使用高斯09计算，爆炸性能使用EXPLO 5计算。尽管这些非金属盐低于中性化合物ETNC（D：7960 m s ^-1，P：27.4 GPa）和PETNC（D：7629）毫秒^-1，P：24.3 GPa），它们具有比TNT更好的高爆轰性能。比较了基于赤藓醇和相应的季戊四醇的高能材料的热稳定性，爆炸速度和爆炸压力。他们还在各自的系列中进行了比较。ETNC和PETNC及其盐的制备步骤短，并且易于以高收率分离，因此具有作为炸药的潜在应用前景。
