| 摘 要： | 本文用差示扫描量热法(DSC)研究了CH_3COONa·3H_2O—C_4H_6O_6拟二元系统,发现其低共熔混合物在50℃时发生同分共熔,其熔化热为209.3J/g。从相变温度和贮热容量考查,该低共容混合物是一种良好的太阳能潜热贮能材料。

| Abstract: | The mixture of pseudo—binary system CH_3COONa·3H_2O—C_H_O_ was investigated to differential scanningcalorimetry in this paper.Eutectic mixture melts congruently at 50℃,the heat of fusion of the eutectic mixture of thispseudo-binary system is found to be 209.3J/g.The temprature of phase change and the capacity of heat storage wasdiscussed,this eutectic mixture is a wonderful material for latent heat storage of solar energy. |
