Publication number: 20090270662Abstract: A process for the production of dichlorotrifluoroethane is described. The process comprises reacting perchloroethylene with hydrogen fluoride in the vapour phase at elevated temperature in at least one reactor in the presence of a fluorination catalyst to produce a composition comprising dichlorotrifluoroethane, hydrogen chloride, unreacted perchloroethylene and unreacted hydrogen fluoride. The composition that is produced is subjected to a separation step to recover a first fraction comprising dichlorotrifluoroethane and a second fraction comprising perchloroethylene and hydrogen fluoride. The second fraction is further separated into a hydrogen fluoride-rich fraction and a perchloroemylene-containing, organic-rich fraction which are then recycled. The dichlorotrifluoroethane that is recovered may be used to prepare pentafluoroethane.Type: ApplicationFiled: December 18, 2006Publication date: October 29, 2009Applicant: INEOS FLUOR HOLDINGS LIMITEDInventors: Clive Robert Giddis, Paul Hendry Stewert

Patent number: 6660130Abstract: Prior to carrying out a gaseous phase chemical reaction, a liquid phase organic compound which is prone to degrade is vaporized at elevated pressures with the aid of a second compound which together with the organic compound produces a mixture having a boiling point less than that of the organic compound. In one embodiment of the invention, vaporization is effected by co-vaporizing a mixture of the two compounds in a vaporiser. In another embodiment, the first compound is injected into a hot gaseous stream and undergoes atomization into droplets which then vaporize within the gaseous stream. The second compound is used to assist the atomization process and/or to sweep atomized droplets of the first compound away from hot surfaces where the first compound would otherwise tend to undergo degradation if the droplets are allowed to reside in contact with such surfaces.Type: GrantFiled: April 11, 2001Date of Patent: December 9, 2003Assignee: Ineos Fluor Holdings LimitedInventors: John David Scott, Charles Brian Blake, Paul Nicholas Ewing, Jeremy Charles Bauser Hunns, Steven Toplis, Andrew Neil Irwin, Mark Spruce
