<p>Improved process for the catalytic hydro-fluorination of saturated or unsaturated organic compounds corresponding to the general formula CwHxClyFz (I) in which w is an integer between 1 and 6, x is an integer between 0 and (2w+1) or between 0 and (2w-1), y is an integer between 1 and (2w+1) or between 1 and (2w-1), z is an integer between 0 and (2w+1) or between 0 and (2w-1) and the sum (x+y+z) is equal to (2w+2), comprising a continuous feed of hydrogen chloride.Process for preparing 1,1,1,3,3-pentafluoropropane starting with 1,1,1,3,3-pentachloropropane, comprising two catalytic reaction steps, in which hydrogen chloride is preferably fed continuously into the reaction medium of at least one of the two reaction steps.</p> |
