Processes for producing branched fluoroalkyl olefins are disclosed. In addition, novel halo-fluoroalkane intermediates are disclosed that may be used in the branched fluoroalkyl olefin production processes. Non-limiting examples of branched fluoroalkyl olefins include branched fluorobutenes, such as 1,3,4,4,4-pentafluoro-3-trifluoromethyl) but-1-ene (HFO-1438ezy). In some aspects, there is disclosed a method for dehydrobrominating 4-bromo-1,1,1,2,4-pentafluoro-2-(trifluoromethyl)butane to produce 1,3,4,4,4-pentafluoro-3-(trifluoromethyl)but-1-ene (HFO-1438ezy).

There is provided a halon purification method capable of simply, safely, and efficiently removing mixed bromine molecules to obtain high purity halon. The halon purification method is a method for removing bromine molecules from crude halon containing halon and the bromine molecules, and the method includes: a contact step of bringing the crude halon into contact with an absorbing liquid containing an aqueous solution containing metal iodide to obtain a mixed liquid containing the crude halon and the absorbing liquid; and a separation step of separating the halon from the mixed liquid to obtain the halon and the absorbing liquid having absorbed the bromine molecules.
