The invention discloses a preparation method of antimony pentafluoride. The method comprises the following steps: 1) crushing a metallic antimony block, and adding to a reactor; 2) vacuumizing the reactor to form negative pressure, and heating to 120 DEG C to remove moisture in the reactor and a material; 3) introducing nitrogen to the reactor, so as to pressurize to constant pressure; 4) slowly introducing fluorine, reacting to generate antimony pentafluoride vapor, beginning to warm in the reaction, and emptying for a plurality of times until the pressure of a buffer tank does not ascend again; 5) preparing an antimony pentafluoride product from the antimony pentafluoride vapor in a condensation reflux mode. The invention simultaneously discloses the reactor for preparing antimony pentafluoride. In the reactor, metallic antimony directly reacts with fluorine, so as to generate antimony pentafluoride, so that the product quality is improved and the process is simplified, and the reactor is convenient to operate. Condensation reflux liquid takes away a part of reaction heat, so as to well control the internal temperature of the reactor; meanwhile, continuous reaction is also ensured; chemical corrosion inside the reactor is reduced. Thus, the service life of the reactor is prolonged.
Description
technical field [0001] The invention relates to a preparation process and equipment for antimony pentafluoride, in particular to a preparation method and a reactor for antimony pentafluoride. Background technique [0002] Antimony pentafluoride can form intercalation compounds with graphite and graphite fluoride, which have much higher conductivity than graphite and graphite fluoride, and may be used as superconducting materials. Antimony pentafluoride is a high-energy fluorinating agent widely used in the pharmaceutical industry (anticancer drugs). [0003] At present, the production method of antimony pentafluoride is relatively complicated, and the purity of the product produced by the reaction is not high, and the separation of impurities is difficult. The requirements for equipment are high. The specific method is as follows: [0004] Add 600 g of antimony pentachloride to an aluminum reactor equipped with a gas inlet pipe, a reflux condenser, and a thermowell to kee...
