摘要
在充有高纯氮气的干燥手套箱内,将硝酸铵和乙酰胺+尿素混合,用称重法准确配制含不同硝酸铵摩尔分数的硝酸铵和乙酰胺+尿素混合样品,利用差示扫描量热法建立了硝酸铵和乙酰胺+尿素二元相图·提出了室温熔盐窗口和室温熔盐深度两个概念,用来衡量形成室温熔盐的能力及其性质·依据相图,指出了该体系能形成室温熔盐,室温熔盐窗口的组成范围是x(NH4NO3)=15%~40%;室温熔盐深度为32K·
In a vacuum atmosphere glovebox system filled with dry nitrogen, over all compositions containing NH4NO3 mole fraction in NH4NO3 and the eutectic mixture of binary system acetamide+urea were accurately prepared by weighting. The phase diagram of NH4NO3 and the eutectic mixture of binary system acetamide+urea was constructed by different scanning calorimetry method. Two concepts,the window of room temperature molten salt (RTMS) and depth of RTMS,were given to represent the capability and property of RTMS. According to the phase diagram,the clear evidence for the formation of RTMS was obtained. The area of the window of RTMS is x(NH4NO3)=15%~40%; the depth of RTMS is 32?K.
