Embodiment 1
[0018] Step 1. Load operation:
[0019] In a 1000L reactor, add 100Kg fluorinated carbon fiber, 1Kg nickel chloride, 400Kg N, N-dimethylformamide, 1Kg 1-vinyl-3-ethylimidazole hexafluorophosphate, and react at 60°C for 15 hours. After standing still for 40 hours, 1Kg of 5,10,15,20-tetrakis(4-pyridyl)porphyrin was added, reacted at 60°C for 15 hours, and the product was separated and dried to obtain the adsorbent.
[0020] Step 2. Adsorption and purification of tungsten hexafluoride:
[0021] Under the conditions of 40°C and 0.5MPa, industrial grade tungsten hexafluoride is adsorbed in a chromatographic column equipped with an adsorbent at a flow rate of 3BV / h to obtain tungsten hexafluoride product. The purity of tungsten hexafluoride is shown in Table 1, and the code is M-1.
Embodiment 2
[0023] Step 1. Load operation:
[0024] In a 1000L reactor, add 100Kg fluorinated carbon fiber, 0.5Kg nickel chloride, 200Kg N, N-dimethylformamide, 0.5Kg 1-vinyl-3-ethylimidazole hexafluorophosphate, and react at 50°C 10h, stand still for 20h, then add 0.5Kg 5,10,15,20-tetrakis(4-pyridyl)porphyrin, react at 40°C for 10h, separate and dry the product to obtain the adsorbent.
[0025] Step 2. Adsorption and purification of tungsten hexafluoride:
[0026] Under the conditions of 10°C and 0.2MPa, industrial-grade tungsten hexafluoride is adsorbed in a chromatographic column equipped with adsorbent at a flow rate of 1BV / h to obtain tungsten hexafluoride product. The purity of tungsten hexafluoride is shown in Table 1, and the code is M-2.
Embodiment 3
[0028] Step 1. Load operation:
[0029] In a 1000L reactor, add 100Kg fluorinated carbon fiber, 2Kg nickel chloride, 500Kg N,N-dimethylformamide, 2Kg1-vinyl-3-ethylimidazole hexafluorophosphate, and react at 80°C for 24h, After standing still for 60 hours, 2Kg of 5,10,15,20-tetrakis(4-pyridyl)porphyrin was added, reacted at 80°C for 20 hours, and the product was separated and dried to obtain the adsorbent.
[0030] Step 2. Adsorption and purification of tungsten hexafluoride:
[0031] Under the conditions of 70°C and 1MPa, industrial grade tungsten hexafluoride is adsorbed in a chromatographic column with adsorbent at a flow rate of 5BV / h to obtain tungsten hexafluoride product. Numbered M-3.
