Embodiment 1
[0122] [Example 1: Mixture of 1233zd(Z) and 3-methylpentane]
[0123] Put the mixed solution (400g) of 1233zd(Z) and 3-methylpentane into an Othmer type gas-liquid equilibrium distillation device, and use a gas chromatograph to obtain the gas phase composition and liquid phase when the equilibrium state is reached. composition. The measurement results are shown in Table 1 and figure 1 .
[0124] [Table 1]
[0125]
[0126] From table 1 and figure 1 It can be seen that the mixed solution of 1233zd(Z) and 3-methylpentane contains 99.9999 mass % to 80.0000 mass % of 1233zd (Z) and 0.0001 mass % to 20.0000 mass % of 3-methylpentane relative to the total amount of the mixed solution. In the case of methylpentane, (like) azeotropic compositions are formed. Among them, when 99.9999 mass% to 90.0000 mass% of 1233zd(Z) and 0.0001 mass% to 10.0000 mass% of 3-methylpentane are contained with respect to the total amount of the mixed solution, the fluctuation of the liquid composit...
Embodiment 2
[0127] [Example 2: Mixture of 1233zd(Z) and 2,3-dimethylbutane]
[0128] Except having used 2,3-dimethylbutane instead of 3-methylpentane, in the same manner as in Example 1, the gas phase composition and liquid phase composition at the time of equilibrium state were calculated|required using the gas chromatograph.
[0129] The measurement results are shown in Table 2 and figure 2 .
[0130] [Table 2]
[0131]
[0132] From Table 2 and figure 2 As shown, the mixed solution of 1233zd(Z) and 2,3-dimethylbutane contains 99.9999 mass% to 75.0000 mass% of 1233zd(Z) and 0.0001 mass% to 25.0000 mass% of the total amount of the mixed solution When 2,3-dimethylbutane is used, an (like) azeotropic composition is formed. Among them, when 99.9999 mass % to 85.0000 mass % of 1233zd (Z) and 0.0001 mass % to 15.0000 mass % of 2,3-dimethylbutane are contained with respect to the total amount of the mixed solution, the fluctuation of the liquid composition becomes more Small and theref...
Embodiment 3
[0133] [Example 3: Mixed solution of 1233zd (Z) and industrial hexane]
[0134] Except for using industrial hexane instead of 3-methylpentane, in the same manner as in Example 1, the gas phase composition and the liquid phase composition in an equilibrium state were determined using a gas chromatograph. The measurement results are shown in Table 3. As an example of industrial hexane used, it contains 2,2-dimethylbutane (2,2-DMB), 2,3-dimethylbutane (2,3-DMB), 2- A mixture of hexane isomers of methylpentane (2-MP), 3-methylpentane (3-MP), n-hexane (n-Hex), methylcyclopentane (MCP), the mixture The composition (mass ratio) was 2,2-DMB / 2,3-DMB / 2-MP / 3-MP / n-Hex / MCP=5.7 / 5.5 / 5.8 / 5.8 / 64.3 / 12.6.
[0135] [table 3]
[0136]
[0137] As can be seen from Table 3, the mixed solution of 1233zd (Z) and industrial hexane contains 99.9999 mass % to 85.0000 mass % of 1233zd (Z) and 0.0001 mass % to 15.0000 mass % of industrial hexane relative to the total amount of the mixed solution. Wi...
