摘要: The present invention discloses a manufacturing process to produce high purity 1234yf from 245eb, which preferably includes the removal of impurities present in 245eb raw material, the dehydrofluorination of 245eb, and the removal of impurities present in final crude product. The disclosed manufacturing process allows the production of a 1234yf product with lower the levels of 1225ye and/or trifluoropropene, preferably in amounts of less than about 500, and 50 ppm, respectively.

摘要: The present invention is a method for 2-fluorobutane to obtain highly purified 2-fluorobutane through a process comprising a step for: bringing crude 2-fluorobutane that includes 5 to 50 wt % of butene into contact with a brominating agent that can form a bromonium ion in an aprotic polar solvent in the presence of water or an alcohol having up to 4 carbon atoms; converting the butene into compounds having a boiling point higher than that of 2-fluorobutane, then recovering 2-fluorbutane from the reaction solution; and purifying the recovered 2-fluorabutane by distillation.

摘要: Processes for isolating 1,1,1,2,3-pentachloropropane from a crude product stream containing the 1,1,1,2,3-pentachloropropane and ferric chloride. The processes may include deep distillation of the crude, treatment of the crude with a reagent that deactivates the ferric chloride followed by distillation on the deactivated crude stream, aqueous washing of the crude product stream to remove ferric chloride followed by distillation on the deactivated crude stream. Other embodiments simultaneously prepare 1,1,2,3-tetrachloroprene and 1,1,1,2,3-pentachloroprane.
