Usage

General Description

1,2-Dibromo-1,1,2-trifluoroethane is a colorless, nonflammable chemical compound that is commonly used as a refrigerant and as a propellant in aerosol sprays. It is also known by the trade name Halon 1301, and is used as a fire extinguishing agent in some countries. This chemical is an organic compound containing bromine and fluorine, and is considered to have low toxicity. However, it is a potent greenhouse gas and has been found to contribute to the depletion of the ozone layer. Due to its harmful environmental impacts, 1,2-Dibromo-1,1,2-trifluoroethane has been phased out of use in many countries and is now regulated under the Montreal Protocol.

A synthetic hexafluoro - 1, 3 - butadiene method (by machine translation)

The invention relates to a method for synthesizing hexafluoro-1,3-butadiene, and belongs to the field of organic chemistry synthesis. The method for synthesizing hexafluoro-1,3-butadiene comprises the following steps: removing hydrogen fluoride from tetrafluoro ethane (HFC-134a) under the action of a catalyst to generate trifluoroethylene; rapidly reacting trifluoroethylene with liquid bromine to generate 1,2-dibromo-1,1,2-trifluoroethane, and removing hydrogen bromide under alkaline conditions to obtain trifluorobromoethylene; and reacting trifluorobromoethylene with activated zinc powder and N,N-dimethyl formamide to generate trifluorovinylzinc, and carrying out a coupling reaction on trifluorovinylzinc under the action of Fe to generate hexafluoro-1,3-butadiene. A solvent can be recovered after above reactions. The method has the advantages of low price and convenient source of raw materials, good stability and long service of the catalyst, simple separation and purification of the above product, and easy industrial production.
