Description

technical field [0001] The invention belongs to the technical field of boron trichloride, in particular to a boron trichloride purification device. Background technique [0002] Boron trichloride is a dangerous chemical. It is mainly used as a doping source for semiconductor silicon or as a catalyst for organic synthesis. It can also be used for the preparation of high-purity boron or organic boron. When preparing boron trichloride, it needs The boron trichloride is purified by using a purification device, but the boron trichloride purified by the existing purification device has low purity, high production cost, complicated operation process and low purification efficiency. Contents of the invention [0003] The object of the present invention is to provide a kind of boron trichloride purifying device, to solve existing problem: the boron trichloride purity after the existing purifying device purifying is lower, and production cost is higher, and operating procedure is co...
