Abstract

The invention relates to a use of a fluorination gas, and the elemental fluorine (F) is present in a high concentration, for example, in a concentration of elemental fluorine (F), especially of equal to much higher than 15 or even 20% by volume, and to a process for the manufacture of a fluorinated compound by direct fluorination employing a fluorination gas, wherein the elemental fluorine (F) is present in a high concentration. The process of the invention is directed to the manufacture of a fluorinated compound, for the exception of fluorinated benzene, by direct fluorination. Especially the invention is of interest in the preparation of fluorinated organic compounds, final products and as well intermediates, for usage in agro-, pharma-, electronics-, catalyst, solvent and other functional chemical applications. The fluorination process of the invention may be performed batch-wise or in a continuous manner.
