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。

New tetravalent pentaerythritol tetranitrocarbamate (PETNC) and its tetraammonium salt have been synthesized by an efficient two-step synthesis starting from the cheap and commercially available pentaerythritol. In addition to full spectroscopic characterization, their thermal stabilities were examined by differential thermal analysis, and their energies of formation calculated. Furthermore, the structures

(PETNC) is deprotonated by nitrogen-rich, alkaline, alkaline earth metal, and silver bases to form the corresponding salts. Thorough analysis and characterization by multinuclear NMR, vibrational spectroscopy, elemental analysis, thermoanalytical techniques, and single crystal X-ray diffraction was performed. Furthermore, the energies of formation for the nitrogen-richsalts were calculated utilizing

The present invention provides manufacturing of and the use of novel polycarbamates and polycarbamides and their condensation reaction products formed by reacting with formaldehyde as wood composite binder resins and in other applications. These resins have thermosetting capabilities and usefulness as binders for wood and other materials with superior resin properties of low cost, colorlessness, exceptionally good binding, and fast curing characteristics, as well as very low formaldehyde emissions. The newly-designed and synthesized novel starting materials for the thermosetting resins of the present invention are diethylene tricarbamide and various polycarbamates derived from corresponding polyols.
