(Problems to be Solved by Conventional Techniques and Inventions) Inert liquid of a perfluoroorganic compound, which is a fluorine compound in which all hydrogen atoms in the molecule are replaced by fluorine atoms (hereinafter referred to as "perfluoro-inert liquid") Is used as a test bath medium for electronic parts, a heat medium for vapor phase soldering, an insulating coolant for electronic devices, an oxygen carrier for artificial blood, a working fluid for heat pipes, and the like.

Various methods are known as methods for producing such a perfluoro-based inert liquid. Of these methods,
An electrolytic fluorination method is known as a method in which the yield of a perfluoro-based inert liquid is relatively high. However, even with this electrolytic fluorination method, an incomplete fluorinated compound having hydrogen atoms bonded in the molecule remains in the product, and although the target fluorinated compound is completely fluorinated, Decomposition products of the active liquid are produced. Among these by-products, incomplete fluorinated compounds cause serious troubles when they are used for the above-mentioned various applications, even if the amount thereof is small. For example, when a perfluorinated organic compound is used as an oxygen carrier for artificial blood, the incomplete fluorinated compound must be completely removed because of the toxicity of the incomplete fluorinated compound to the living body. In addition, in the case of other uses, the incomplete fluorine compound is decomposed under the environment of high temperature, acid, alkali, etc., and causes generation of hydrogen fluoride and other harmful substances.

Therefore, various methods for removing incomplete fluorinated compounds contained in the perfluoro-based organic compound obtained by fluorination have been tried. For example, a method of separating an incomplete fluorinated compound from a perfluoro-based inert liquid by distillation, or a reaction product of the incomplete fluorinated compound and the above-mentioned base by treating with a base containing an alkali metal or an alkaline earth metal. And then removing this reaction. However, with the former method by distillation, it is extremely difficult to selectively separate incomplete fluorinated compounds. Further, in the latter method, high temperature or long time treatment is required as the treatment condition with the base,
There was an unavoidable loss of the target perfluoro-based inert liquid due to the treatment operation with the base, and there was a problem in that the yield decreased.

On the other hand, the perfluorinated inert liquid containing the obtained incomplete fluorinated product as it is and then fluorinated with a fluorine gas is used to efficiently and completely fluorinate the perfluorinated inert liquid. A liquid can be obtained.

Devices such as blowers and compressors are known as devices for supplying fluorine gas into the fluorination reactor.
When supplying fluorine gas with these devices, special consideration must be taken to prevent leakage of fluorine gas when selecting the device. In addition, it is necessary to pay close attention to daily operation and maintenance. Therefore, in addition to the above-mentioned device for safely supplying the fluorine gas, a device for producing the perfluoro-based inert liquid favorably has been desired.

As a result, by connecting the fluorine gas supplier using the perfluoro-based inert liquid with the reactor by the ejector, the perfluoro-based inert liquid and the fluorine gas discharged from the ejector in the reactor are separated. In addition, an apparatus for producing a perfluoro-based inert liquid by fluorinating an incompletely fluorinated compound separately supplied by the fluorine gas was developed to solve the above problems.
