storage method

this product should be sealed and stored in a cool and dry place.

synthesis method

while stirring, quickly add anhydrous aluminum trichloride to the melted freon112medium, heat preservation stir2-3h, then warm it up to 60-70℃, insulation filtration, fractionation of the filtrate, collection91-92℃fraction, get2,2-difluorotetrafluoroethylene ethyl chloride. yield70%.

purpose

intermediate of the pharmaceutical anesthetic methoxyflurane; can be used as foaming agent, propellant, and refrigerant.
