Uses

Used in Chemical Industry:
1,1,1,4,4,4-HEXAFLUORO-2-BUTENE is used as a monomer for the production of polytetrafluoroethylene (PTFE), a versatile polymer known for its exceptional chemical stability, non-stick properties, and high-temperature resistance. It is widely used in various applications, including non-stick coatings, gaskets, seals, and electrical insulation.
Used in Refrigeration Industry:
1,1,1,4,4,4-HEXAFLUORO-2-BUTENE is used as a refrigerant due to its thermodynamic properties, which make it suitable for use in refrigeration systems. However, its environmental impact as a greenhouse gas and an ozone-depleting substance has led to the development of alternative refrigerants with lower environmental impact.
Used in Synthesis of Fluorochemicals:
1,1,1,4,4,4-HEXAFLUORO-2-BUTENE serves as a precursor in the synthesis of other fluorochemicals, which have various applications in industries such as pharmaceuticals, agrochemicals, and materials science. These fluorochemicals often exhibit unique properties, such as enhanced stability and reactivity, making them valuable in the development of new products and processes.

One-Step Process for Hexafluoro-2-Butene

Disclosed is a one step process for making of 1,1,1,4,4,4-hexafluoro-2-butene. More specifically, the present invention provides a process for making hexafluoro-2-butene, continuously, from 2-chloro-3,3,3-trifluoropronene using Fe2O3/NiO impregnated carbon catalyst at 600° to 650° C.

THERMAL AND THERMOOXIDATIVE STABILITY OF OZONE-SAFE FREONS

The thermal stability of freons 134-a (CF3CH2F), 134 (CHF2CHF2), and 133-a (CF3CH2Cl) was studied experimentally by the pulsed adiabatic compression method.The conversion of the freons, beginning at a value of 0.0002, was determined from the carbon balance of the reaction products, calculated from the chromatographic data.The Arrhenius expressions for the total rate constants of thermal decomposition of the freons are presented.The intermediates of the thermal transformations of the freons were recorded by kinetic spectroscopy in the ultraviolet and visible regions.The UV spectrum of the carbene :CHCF3 with characteristic absorption maxima at λ 235 and 430 nm is described for the first time.

A Novel Hydrodechlorinative Dimerization of Chlorofluorocarbons over Supported Ni Catalysts

1,1,1-Trichloro-2,2,2-trifluoroethane or 1,1-dichloro-1,2,2,2-tetrafluoroethane, both of which have CF3 group, dimerizes over supported Ni catalysts at an elevated temperature (723 K) into corresponding C4-compounds in good to moderate yields.
