Title:
PROCESS FOR PREPARING FLUOROBENZENE BY DIRECT FLUORINATION
Document Type and Number:
WIPO Patent Application WO/2021/031431
Kind Code:
A1
Abstract:
Disclosure relates to a use of a fluorination gas, wherein the elemental fluorine is present in a high concentration, for example, in a concentration of elemental fluorine, especially of equal to much higher than 15 % or even 20% by volume, and to a process for the manufacture of a fluorinated benzene by direct fluorination employing a fluorination gas, wherein the elemental fluorine is present in a high concentration.
