Usage

General Description

1,1-Dibromotetrafluoroethane, commonly known as Halon 1202, is a chemical compound used primarily in fire suppression systems. This chemical is a liquefied gas, non-conductive, colorless, and heavier than air, which enables it to smother flames at ground level. Although very effective, the production of 1,1-Dibromotetrafluoroethane has been largely phased out due to its high ozone depleting potential. Consequently, it is usually found in older systems and is frequently replaced with more environmentally friendly alternatives when those systems are serviced or decommissioned.

Polymer chemistry. Part V. γ-Ray induced telomerisation reactions involving 1,1-difluoroethene and hexafluoropropene

Telomerisation reactions have been investigated for the alkenes 1,1-difluoroethene (5) and hexafluoropropene (3) with the telogens CF2Br2 (1), CF3CFBr2 (8) and CF3CBr3 (9), as a means of preparing telomers and co-telomers.The efficiency of chain transfer increases as 1 /= 8 9.Surprinsingly, co-telomerisations of 5 with 3 occurred more efficiently than the corresponding telomerisations with 5 alone.The effects of solvent are described. - Keywords: Telomerisation; γ-Ray induction; 1,1,-Difluoroethene; Hexafluoropropene; NMR spectroscopy; Mass spectrometry

A synthetic hexafluoro -1,3-butadiene method

The invention relates to a method for synthesizing hexafluoro-1,3-butadiene, and belongs to the field of organic chemistry synthesis. The method comprises the following steps: carrying out gas phase bromination on tetrafluoroethane HFC-134a to generate dibromotetrafluoroethane CF3CBr2F, and carrying out a coupling reaction on dibromotetrafluoroethane, activated zinc powder and N,N-dimethyl formamide under the action of Fe to generate hexafluoro-1,3-butadiene. A solvent after the above reactions can be recycled. The method has the advantages of low price and convenient source of raw materials, high product yield, simple separation and purification of the above product, and easy industrial production.
