多元醇硝酸酯增塑硝化棉体系的热力学相容性研究

Thermodynamic Compatibility of Components in Nitro Cellulose Plasticized by DEGDN and TEGDN

利用气相色谱法（ＧＣ）和光学显微干涉法研究了硝化二乙二醇（ＤＥＧＤＮ）和硝化三乙二醇（ＴＥＧＤＮ）增塑的硝化棉（ＮＣ）体系中各组分相互作用的热力学性能。所得的混合偏摩尔熵值降低的事实表明：组分间存在较强的作用能。得到了ＮＣＤＥＧＤＮ和ＮＣＴＥＧＤＮ体系的相图。

The interaction thermodynamics of components in nitro cellulose plasticized by diethylene glycol dinitrate (DEGDN) or triethylene glycol dinitrate (TEGDN) is studied by use of GC and optical micro interferometer. The decrease of partial entropy of mixing indicates the existance of strong interaction energy between the components exists. The phase diagram of NC DEGDN and NC TEGDN are obtained.
