PROCESS OF FLUORINATING INORGANIC OR ORGANIC COMPOUNDS BY DIRECT FLUORINATION

WIPO Patent Application WO/2021/031432

A1

Presented is a use of a fluorination gas, wherein the elemental fluorine (F 2) is present in a high concentration, for example, in a concentration of elemental fluorine (F 2), especially of equal to much higher than 15 or even 20% by volume (i.e., at least 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 2) is present in a high concentration. The process is directed to the manufacture of a fluorinated compound, for the exception of fluorinated benzene, by direct fluorination. Especially presented 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 may be performed batch-wise or in a continuous manner. If the said process is performed batch-wise, a column (tower) reactor may be used. If the process is continuous, a microreactor may be used.
