colorless and odorless non-combustible gas. Melting Point -156.2 °c. Boiling point -29.4 °c. The relative density of liquid was 1. 565. Decomposition of pentafluorobutene and octafluorobutene above 500 °c.
The tetrafluoroethylene enters the high temperature cracking furnace through the pressure gauge, and the cracking gas is sent to the rectification section after acid removal, drying and compression, and then subjected to crude distillation, freezing, degassing and rectification to obtain the finished product.
One of the monomers for synthesizing fluorine-containing polymer materials (such as fluorine rubber F20-41, F246 and fluorine plastic F46). It can also be used as raw materials for perfluorosulfonic acid ion exchange membrane (for salt electrolysis), fluorocarbon oil and perfluoropropylene oxide.

Introduction | hexafluoropropylene (hexafluoropropylene, HFP) is one of the basic raw materials of organic fluorine industry, its importance is second only to tetrafluoroethylene, it is a comonomer of many fluorine-containing copolymers and an intermediate of many fluorine-containing compounds. Under normal circumstances, hexafluoropropylene is a colorless and tasteless gas, toxic, in the air does not burn, boiling point -29.4 ℃. Under pressurized conditions, hexafluoropropylene can be stored and transported in a liquid state without the addition of a stabilizer. |
Application | copolymerization of hexafluoropropylene and tetrafluoroethylene to obtain Poly (perfluoroethylene propylene) (FEP), compared with PTFE,FEP not only has the remarkable characteristics of melt processing, but also has excellent dielectric properties, electrical insulation properties, chemical solvent resistance, flame retardant properties, high and low temperature resistance, it can be used at a temperature of -80 °c to 200 °c for a long period of time. |
Application | can be used to prepare a variety of fluorine-containing fine chemical products, pharmaceutical intermediates, fire extinguishing agents, etc, fluorine-containing polymer material can also be prepared This product is one of the monomers for synthesizing fluorine-containing polymer materials (such as fluorine rubber F20-41, F246 and fluorine plastic F46, etc.). It can also be used as raw materials for perfluorosulfonic acid ion exchange membrane (for salt electrolysis), fluorocarbon oil and perfluoropropylene oxide. it can prepare a variety of fluorine-containing fine chemical products, pharmaceutical intermediates, fire extinguishing agents and other raw materials, and can also prepare fluorine-containing polymer materials |
production method | is obtained by pyrolysis of tetrafluoroethylene. The tetrafluoroethylene is passed into a high-temperature cracking furnace for cracking at 700 ° C., and the cracking gas is subjected to crude distillation after acid removal, drying and compression, the distillate is frozen and degassed, and finally the finished product is obtained by distillation. |
