PROCESS FOR THE MANUFACTURE OF ALPHA-IODOPERFLUOROALKANES AND ALPHA,OMEGA-DIIODOPERFLUOROALKANES

摘要

The invention relates to a process for the manufacture of a-iodoperfluoroalkanes and α,ω-diiodoperfluoroalkanes of general formula: (1) A(C2F4)n1, wherein: A is selected from F, CF3 and I and n is an integer equal to or higher than 1, with the proviso that, when A is F, n is an integer higher than 1 said process comprising heating a mixture [mixture (M1)] containing: —a compound selected from I2, CF3I, CF3CF2I and C2F4I2; —TFE; —and CO2 at definite temperatures and concentrations of CO2.
