    摘要: The invention relates to a use of a fluorination gas, wherein the elemental fluorine (F 2 ) is preferably 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 benzene starting from benzoic acid by direct fluorination employing a fluorination gas, wherein the elemental fluorine (F 2 ) is preferably present in a high concentration, and subsequent decarboxylation of the benzoic acid hypofluorite obtained by direct fluorination. The process of the invention is also directed to the manufacture of a benzoic acid hypofluorite by direct fluorination of benzoic acid. Especially the invention is of interest in the preparation of fluorinatedbenzene, 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. If the process of the invention is performed batch-wise, a column (tower) reactor may be used. If the process of the invention is continuous a micro reactor may be used. The invention is characterized in that the starting compound is benzoic acid, and the fluorinated compound produced is a benzoic acid hypofluorite obtained by direct fluorination, which benzoic acid hypofluorite can be converted by decarboxylation to a fluorinated benzene, preferably monofluorobenzene.
