Embodiment 1
[0043] First, clean and dry the reactor 3, add 2 kg of titanium metal with a purity of 98.5% into the reactor 3, close the reactor 3, and evacuate it to -0.10MPa (gauge pressure), and after the leak test of the reactor 3 is qualified, remove it Preheat to 100°C.
[0044] Secondly, slowly open the fluorine gas inlet valve 2 in front of the reactor 3, and feed fluorine gas with a purity of 96% into the reactor 3, so that the fluorine gas and metal titanium are contacted in the reactor 3 to undergo a synthesis reaction to generate gaseous tetrafluoride. For the crude titanium product, the reaction process pressure is -0.05MPa, and the temperature in the reactor 3 is 200°C.
[0045] Again, the gaseous titanium tetrafluoride from the reactor 3 enters the purifier 4, the temperature inside the purifier 4 is 150° C., and the gauge pressure inside the purifier 4 is -0.10 MPa.
[0046] Finally, 4.0 kg of crude gaseous titanium tetrafluoride was collected in the purifier 4. The te...
Embodiment 2
[0048] First, the reactor 3 is cleaned and dried, 2 kg of titanium metal with a purity of 98.5% is added to the reactor 3, the reactor 3 is sealed, and the gauge pressure is evacuated to -0.09MPa. Heat to 150°C.
[0049] Secondly, slowly open the fluorine gas inlet valve 3 in front of the reactor 3, and feed fluorine gas with a purity of 96% into the reactor 3, so that the fluorine gas and metal titanium are contacted in the reactor 3 to undergo a synthesis reaction to generate gaseous tetrafluoride. Titanium crude product, the reaction process pressure is 0MPa, and the temperature of reactor 3 is 310°C.
[0050] Again, the titanium tetrafluoride coming out of the reactor 3 enters the purifier 4, the temperature inside the purifier 4 is 200°C, and the internal surface pressure of the purifier 4 is -0.05MPa.
[0051] Finally, 4.7 kg of crude gaseous titanium tetrafluoride was collected in purifier 4. Cool the temperature in the purifier to normal temperature, condense the gas...
Embodiment 3
[0053] First, the reactor 3 is cleaned and dried, 2 kg of titanium metal with a purity of 98.5% is added to the reactor 3, the reactor 3 is sealed, and the gauge pressure is evacuated to -0.08MPa. Heat to 200°C.
[0054] Secondly, slowly open the fluorine gas inlet valve 2 in front of the reactor 3, and feed fluorine gas with a purity of 96% into the reactor 3, so that the fluorine gas and metal titanium are contacted in the reactor 3 to undergo a synthesis reaction to generate titanium tetrafluoride For the crude product, the gauge pressure during the reaction was 0.05MPa, and the temperature in the reactor 3 was 500°C.
[0055] Again, the gaseous titanium tetrafluoride from the reactor 3 enters the purifier 4, the temperature inside the purifier 4 is 280° C., and the gauge pressure inside the purifier 4 is 0 MPa.
[0056] Finally, 4.5 kg of crude gaseous titanium tetrafluoride was collected in the purifier 4. Cool the temperature in the purifier to normal temperature, cond...
