中文摘要：

热致相变材料四卤合金属酸（Ⅱ）二烷基铵具有层状钙钛矿结构．本文合成了四氯合锌酸十四铵n-（C14H29NH3）2ZnCl4和四氯合锌酸十六铵n-（C16H33NH3）2ZnCl4，并在两种材料的乙醇溶液中结晶出一系列二元混合体系．对纯组份及各个二元体系采用Kissinger和Ozawa两种动力学模型处理差示扫描量热（DSC）测定的热分析曲线，研究了非等温固-固相变动力学，计算了固-固相变过程的活化能和反应级数，两种方法的计算结果相接近，二元体系表观活化能E0值，随着C14Zn质量分数的增加，活化能呈波动变化、CnZn及二元体系的反应级数为1.

英文摘要：

The thermotropic phase transitions in the perovskite type layer compound n- （C14H29NH3 ）zZnCl4 and n - （ C16H33NH3 ）2ZnCl4n - （ C10H21NH3 ）2ZnCl4 were synthesized and a series of their mixtures were prepared from ethanol solutions. Nonisothermal kinetics of solid - solid phase transitions in C14Zn, C16Zn and their binary system was investigated by DSC. Kissinger and Ozawa methods are applied to determine the activation energy and reaction order of the solid - solid transitions. The results of two methods are in agreement. The value of the activation energy Ea showed a waving dependence on the XC14Zn. The reaction order of C.Zn and their binary system is 1.
