Usage

Uses

Used in Air Conditioning and Refrigeration Industry:
(E)-1,3,3,4,4,4-hexafluorobut-1-ene is used as a refrigerant for air conditioning and refrigeration systems due to its low global warming potential and minimal ozone depletion potential. This makes it a more environmentally friendly alternative to traditional refrigerants.
Used in Chemical Industry:
(E)-1,3,3,4,4,4-hexafluorobut-1-ene is used as a precursor for the production of other fluorinated compounds in the chemical industry. Its high stability and inertness make it a valuable component in various industrial applications, contributing to the synthesis of a wide range of products.
It is important to handle and store (E)-1,3,3,4,4,4-hexafluorobut-1-ene with care, as it is a potent greenhouse gas when released into the atmosphere. Proper safety measures and regulations should be followed to minimize its environmental impact.

Heterocyclic Polyfluoro-compounds. Part 31. Photochemical Oxetan Formation from Fluoroketones and Perfluoroaldehydes and 1,2-Difluoroethylene

The photochemical addition of five fluoroketones (hexafluoro-, chloropentafluoro-, 1,3-dichlorotetrafluoro-, 1,1,3-trichlorotrifluoro-, and 1,1,1-trifluoro-propan-2-one) and the perfluoroaldehydes RFCHO (RF=CF3, C2F5, or n-C3F7) to (Z)- or (E)-1,2-difluoroethylene at λ > 300 nm has been studied.Oxetan formation dominates with hexafluoropropan-2-one, but there is increasing competition from reactions involving free radicals arising from photolysis of the ketone as the chlorine content is increased.Oxetan formation occurs with little stereospecificity.The aldehydes give r-2-perfluoroalkyl-t-3,c-4-, and -c-3,t-4-, and -t-3,t-4-difluoro-oxetans, in the ratio 1.0 : 1.7 +/- 0.2 : 1.3 +/- 0.1, respectively, and in high yield (78-94percent).A small amount of olefin isomerisation occurred. Flow pyrolysis of the oxetans from hexafluoroacetone yields (Z)- and (E)-1,2-difluoroethylene and the olefin (CF3)2C=CHF, the oxetan yields the olefins (Z)- and (E)-CHF=CHF and (CF2Cl)2C=CHF, and r-2-pentafluoroethyl- or heptafluoro-n-propyl-c-3,t-4-difluoro-oxetans yield mainly the olefins (Z)- and (E)-RFCHC=CHF (RF=C2F5 or n-C3F7).
