ABSTRACT:
A process for the manufacture of perfluoroalkyl iodide adducts is provided, wherein a perfluoroalkyl iodide is reacted with an olefine in the presence of an amine and a metal salt of groups Ia to IVa or Ib to VIIIb of the periodic system, the amine and metal salt optionally being in the form of an amine-metal salt complex. The end product optionally may be deiodized. The adducts may be used as intermediates for the manufacture of products used for finishing textiles, paper or leather and other solids, especially for rendering such substrates oleophobic or hydrophobic.
