Process of Fluorinating Inorganic or Organic Compounds by Direct Fluorination
The invention relates to a use of a fluorination gas, and the elemental fluorine (F.sub.2) is present in a high concentration, for example, in a concentration of elemental fluorine (F.sub.2), 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.sub.2) 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.
Process for Preparing Fluorobenzene by Direct Fluorination
The invention relates to a use of a fluorination gas, wherein the elemental fluorine (F.sub.2) is present in a high concentration, for example, in a concentration of elemental fluorine (F.sub.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 by direct fluorination employing a fluorination gas, wherein the elemental fluorine (F.sub.2) is present in a high concentration. The process of the invention is directed to the manufacture of a fluorinated benzene by direct fluorination. Especially the invention is of interest in the preparation of fluorinated benzene, 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 microreactor may be used. The invention is characterized in that the starting compound is benzene, and the fluorinated compound produced is a fluorinated benzene, preferably monofluorobenzene.

Feeding process of chlorine fluoride
A chlorine fluoride feeding device and feeding process are provided that can stably generate industrially applicable chlorine fluoride (ClF), control flow rate, and provide continual feed. The feeding process of chlorine fluoride of this invention is a feeding process to feed chlorine fluoride generated by loading a gas that contains fluorine atoms and a gas that contains chlorine atoms to a flow-type heat reactor or a plasma reactor, and it can stably generate and safely feed chlorine fluoride for a long time by reacting chlorine fluoride that is difficult to pack at a high pressure, such that an amount that can be packed in a gas container such as a gas cylinder is limited, with two or more types of gas materials that can be packed safely in a gas container by liquefaction, or with such gas material and a solid material.
