实验思路：NH2CONHNH2•HCl+NaNO2—->NH2CON3+NaCl+2H2O ⑴NH2CON3+3NaOH——>NaN3+Na2CO3+NH3+H2O ⑵实验材料：盐酸氨基脲（市售），亚硝酸钠

首先需要制备1,2,4-三唑-5-酮，即TO，为此可将盐酸氨基脲溶于85%甲酸中，再蒸馏去除过量的甲酸以使TO析出。然后让70%硝酸和TO固体反应制得NTO，经过后处理可得纯品。

NH2CONHNO2+H2O+H2SO4⒊使用光亮铁片作电极，将硝基脲溶解于含氯化铵与盐酸的溶液中通电电解（文献）NH2CONHNO2+H2SO4+3H2O——>NH2CONHNH2•H2SO4+3/2O2⒋硫酸氨基脲与亚硝酸钠反应得叠氮甲酰胺
