Description
technical field [0001] The invention relates to the field of phosphorus pentachloride feeding, in particular to a feeding device and a feeding method of phosphorus pentachloride. Background technique [0002] Phosphorus pentachloride is light yellow powder (granule) with pungent odor and easy to sublime. It easily reacts with water to form phosphoric acid and hydrogen chloride, which produces white smoke and special pungent odor, which strongly stimulates eyes and respiratory tract. [0003] In the current chemical production, the feeding method of phosphorus pentachloride is mainly solid feeding, such as a phosphorus pentachloride feeding device and a feeding method thereof in the Chinese invention patent application publication number CN105668539 A. The feeding device includes a phosphorus pentachloride feeding device. The container, pipeline, vacuum system, upper container, phosphorus pentachloride reactor, first valve, second valve, third valve, pressure regulating valv...
