摘要
以盐酸脒基脲为原料,通过水解、复分解反应,合成了N-脒基脲二硝酰胺盐(GUDN),总收率可达79%。通过元素分析、红外光谱、紫外光谱等手段鉴定了其结构;测试了GUDN的密度、摩擦感度和撞击感度,并与ADN的性能进行比较。研究表明,GUDN不吸潮,热稳定性好,感度低,相容性较好,能与RDX,HM X等火炸药常用组分相容。应用试验表明,GUDN可用于改性双基推进剂。
N-guanylurea dinitramide (GUDN) was synthesized with N guanylurea hydrochloride as primary substance by hydrolysis and double decomposition reaction in turn and the overall yield of GUDN is 79%. The structure of GUDN was identified by elemental analysis,IR and UV. Some properties of GUDN were determined as : density ,1. 755 g/cm^3;friction senstivity,0 (2.45MPa,20mg,66°);H50〉197cm (2kg) etc. And its properties were compared with properties of ADN. GUDN has low sensitivity,good thermal stability and unhygroscopicity. The results obtained by DSC show that GUDN is compatible with common energetic materials such as HMX and RDX. Application tests indicate that GUDN can be used in double base propellant.
