- W2374589568 abstract "Pentachloropyridine (PCP) was synthesized by reacting pyridine with chlorine in vapor phase at high temperature for a short time in a fixed bed. Analyzing the reaction mechanism, a series of catalysts were prepared whose active components are salts of II, VIII and IB group metal or their mixtures, and the salts can be chlorides, sulfates, nitrates or carbonates. These catalysts were tested under various conditions: temperature from 493K to 663K, space velocity from 200hr-1 to 1200hr-1, and mole ratio of pyridine to chlorine (R) from 1:6 to 1:12. Results indicate that mixtures of Ba, Ca, La and Rh salt show stronger activity in the process. The yield of PCP can be up to 95% with a purity of 96% (GC) in the presence of the prepared catalyst B. Further investigation tells the feasible reaction condition for the catalyst B: temperature 590~ 650K, R 8.5 and space velocity 600~800 hr-1 ." @default.
