Abstract: The thermotropic phase transitions layer compound in the perovskite type (n-C₁₀H₂₁NH₃)₂ZnCl₄and (n-C₁₈H₃₇NH₃)₂ZnCl₄were synthesized and, at the same time, a series of mixtures C₁₀Zn/C₁₈Zn were prepared. The experimental binary phase diagram of C₁₀Zn/C₁₈Zn was established by means of differential scanning calorimetry (DSC) and X-ray diffraction. In the phase diagram, compound (n-C₁₀H₂₁NH₃)(n-C₂₁H₃₇NH₃)ZnCl₄and two eutectoid invariants were observed; two eutectoid temperatures are about 53℃and 58℃. Contrasting with other similar systems, there are three noticeable solid solution ranges at the left and right boundary and middle of the phase diagram.
