The application discloses an energetic metal complex and a synthesis method thereof, and the method is characterized by the molar ratio of 3-aminomethyl-4,5-diamino-1,2,4-triazole, rubidium nitrate and nitric acid being 1:1:1-6, after the feeding is completed, the reaction system is heated to 25-100 DEG C to react, and the reaction time is 0.5-4 hours. After the reaction is completed, the reaction system is cooled to room temperature, filtered, washed and dried to obtain the energetic metal complex [TATT][Rb](NO3)3. The triazol ring with high nitrogen content is selected as a basic skeleton, and the metal complex is obtained by further reacting with the rubidium nitrate and the nitric acid, the single crystal density of the metal complex at normal temperature reaches 2.078 g / cm 3 , the thermal stability reaches 230 DEG C, the electronic density is as high as 4.6419*10 21 / m 3 , the electronic temperature reaches 0.58683 eV, and the metal complex has a great application prospect in the direction of plasma explosives.

This invention discloses a separation process for a mixed salt containing rubidium nitrate and sodium nitrate. Based on the ternary system (RbNO3-NaNO3-H2O) phase diagram, the process achieves the separation of rubidium nitrate and sodium nitrate by utilizing the salt precipitation pattern during heating and cooling. The two circulating mother liquors (E2 and E3, or E1 and E3) can be recycled in the production process, resulting in no wastewater or waste residue discharge. The rubidium nitrate and sodium nitrate obtained by this method have high purity, and the process is simple to operate, environmentally friendly, stable, and reliable, making it suitable for industrial production.

The invention discloses a catalytic synthesis method of trifluoroiodomethane, which comprises the following steps: introducing gaseous CF3H, I2 and O2 into a reaction container according to a feeding ratio of CF3H: I2: O2 of 3: 1: 0.4, and reacting by taking rubidium nitrate loaded activated carbon as a catalyst; adjusting the addition amount of oxygen according to the conversion rate of CF3H; when the conversion rate of the CF3H is lower than 30%, the introduction of the CF3H, the I2 and the O2 is stopped. According to the catalytic synthesis method of trifluoroiodomethane, generation of carbon deposition is reduced by adjusting the introduction amount of oxygen, meanwhile, excessive ablation of the activated carbon carrier is avoided, and the service life of the catalyst is prolonged.
