Definitions
- the present invention relates to compositions comprising 1,1,1,2,2-pentafluoropropane and trans-1,3,3,3-tetrafluoropropene, useful in many fields of application.
- Halocarbon based fluids have found many applications in various industrial fields, including heat transfer fluids, propellants, foaming agents, blowing agents, gaseous dielectrics, polymerization medium or monomer, carrier fluids, abrasives, drying agents and fluids for power generation unit. Particular importance is given to fluids with low impact on the environment such as 2,3,3,3-tetrafluoropropene.
- 2,3,3,3-tetrafluoropropene Some processes for producing 2,3,3,3-tetrafluoropropene involve the formation of 1,1,1,2,2-pentafluoropropane and various isomers such as trans-1,3,3,3-tetrafluoropropene. Thus, the final purification of 2,3,3,3-tetrafluoropropene requires the separation of 1,1,1,2,2-pentafluoropropane and trans-1,3,3,3-tetrafluoropropene, which are the impurities.
