摘　　要：氨基胍碳酸盐是一种重要的合成化工原料,目前应用的氨基胍碳酸盐的合成工艺主要有肼化、肼解和还原。本文主要探究的是应用锌粉和铁粉做还原剂将硝基胍还原为氨基胍。但首先要以双氰胺与硝酸铵为原料反应获得硝酸胍,再用浓硫酸处理硝酸胍得到硝基胍,最后通过还原将硝基胍还原为氨基胍,并对产物进行了表征,探讨了不同的还原方法对产率造成影响的原因。Aminoguanidine carbonate is an important synthetic chemical raw material.At present,the synthesis process of aminoguanidine carbonate is mainly deuterated,decomposed and reduced.This paper mainly explores the use of zinc powder and iron powder as a reducing agent to reduce nitroguanidine to aminoguanidine.Firstly,lanthanum nitrate is reacted with ammonium nitrate as raw material to obtain cerium nitrate,then cerium nitrate is treated with concentrated sulfuric acid to obtain nitroguanidine,and finally nitroguanidine is reduced to aminoguanidine by reduction.Finally the products were characterized and the reasons for the effects of different reduction methods on the yield were discussed.
