Embodiment 1
[0081] Put 30g of acid chloride (0.0144mol) into a 250ml four-necked flask containing 100g of dichlorobenzene, heat the oil bath to 130°C, add dropwise 0.84g (0.00288mol) of rosinamine, and 3.67g (0.02592mol) of 3-chloro- The dichlorobenzene solution of 2-methylaniline was added dropwise for 30 minutes, and after the dropwise addition was completed, the temperature was raised to 150° C. for 3 hours. Filtering at lower temperature, washing with methanol and then water, recovering the solvent, and drying the filter cake to obtain the bis-azo condensation compound.
[0082] The electron microscope observation results of the figure 2 Shown; Its X-ray diffraction result is as follows Figure 4 shown; its infrared spectrum is shown in Figure 6 Shown; its elemental analysis results are shown in Table 1 below.
Embodiment 2
[0084] Put 30g of acid chloride (0.0144mol) into a 250ml four-necked flask containing 100g of dichlorobenzene, heat the oil bath to 130°C, add dropwise 1.25g (0.00432mol) of rosinamine, and 3.46g (0.02448mol) of 3-chloro- The dichlorobenzene solution of 2-methylaniline was added dropwise for 30 minutes, and after the dropwise addition was completed, the temperature was raised to 150° C. for 3 hours. Filtering at lower temperature, washing with methanol and then water, recovering the solvent, and drying the filter cake to obtain the bis-azo condensation compound.
[0085] Its electron microscope observation result, X-ray diffraction pattern and infrared spectrogram are similar to the product obtained in Example 1, and its elemental analysis results are shown in Table 1 below.
