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.

Method for preparing hexafluoro-1,3-butadiene

The invention relates to a method for preparing hexafluoro-1,3-butadiene. The method comprises the following steps: performing reduction dechloridation on 1,2-dichloro-1,1,-2-halothane with zinc powder to obtain a CF2=CHF gas phase intermediate product, introducing into liquid bromine to carry out an addition reaction, and obtaining CBrF2CHBrF; evaporating CBrF2CHBrF in an evaporator to generate a gas, and using a reaction tube filled with a first catalyst to remove one molecule HBr and generate trifluorovinyl bromide; performing two steps of reactions on the trifluorovinyl bromide under the action of the zinc powder, the solvent and a second catalyst, thereby obtaining the hexafluoro-1,3-butadiene. The method has the advantages of being simple in process, high in yield, easy in raw material obtaining, easy in industrialization, green and environment-friendly.
