Process for synthesizing chloropentafluoroethane from dichlorotetrafluoroethane and hydrofluoric acid |
| abstract |
PRECISION OF DISCLOSURE: The subject of the invention is a manufacturing process in the gas phase of chloropentafluoroethane, by the action of hydrofluoric acid on dichlorotetrafluoroethane in presence of a catalyst, said catalyst being prepared in causing an alumina, the content of which reacts in the gas phase sodium oxide is less than 300 ppm and whose volume pores with a radius of 40 Angstr? ms and more is greater than 0.7 cm3 / g with hydrofluoric acid or with a mixture hydrofluoric acid and air, nitrogen or a compound fluorinated. This method according to the invention has the advantage of being simple, flexible and economical. |
