Method and apparatus for producing fluorine-containing organic compound
Provided is a method for producing a fluorine-containing organic compound. The method can immediately detect the occurrence of a side reaction in direct fluorination reaction using fluorine gas and can give a highly pure fluorine-containing organic compound at a high yield. A raw material liquid (1) containing a raw material organic compound having a hydrogen atom and two or more carbon atoms is reacted with fluorine gas in a reaction container (11) to replace the hydrogen atom of the raw material organic compound with a fluorine atom to give a fluorine-containing organic compound. In the reaction, tetrafluoromethane contained in a gas phase (2) in the reaction container (11) is continuously measured, and the amount of the fluorine gas supplied to the reaction container (11) is controlled depending on the measured value of the tetrafluoromethane.

METHOD FOR PRODUCING DICHLORO ADDITION PRODUCT OF ALIPHATIC OLEFIN BY PHOTOCATALYSIS UNDER VISIBLE LIGHT
The invention provides a method for producing a dichloro addition product of an aliphatic olefin by photocatalysis under visible light. The method includes reacting an aliphatic olefin as a substrate with hydrochloric acid as a chlorine source in an organic solvent under visible light irradiation in the presence of copper chloride with visible light absorption ability as a catalyst, to obtain the dichloro addition product of the aliphatic olefin, wherein the reaction is carried out under an oxygen-containing atmosphere, the aliphatic olefin comprises a carbon-carbon double bond and a C9-C15 aliphatic chain connected to the carbon-carbon double bond by a covalent bond. In the invention, visible light is used to provide the energy and a transition metal chloride with visible light absorption ability is used to undergo light-induced electron transfer from chloride with a reaction substrate, thereby initiating an addition reaction to obtain a dichloro addition product.
