Claims (1)

Способ электрохимического фторирования предусматривает пропускание посредством принудительной конвекции жидкой смеси, содержащей безводный фтористый водород, фторирующегося органического соединения, например трипропиламина, при температуре и давлении, при которых поддреживается в основном сплошная жидкая фаза, между электродами биполярного электродного пакета. Биполярный электродный пакет содержит множество в основном параллельных, установленных с зазором между ними электродов, выполненных из электропроводного материала, например никеля, существенно инертного к безводному фтористому водороду и активного, когда используется в качестве анода для электрохимического фторирования; электроды пакета электрически включены либо последовательно, либо последовательно-параллельно. На биполярный электродный пакет наложена разность потенциалов, создающая постоянный ток, который вызывает образование фторированного органического соединения, например перфтортрипропиламина. Способ осуществляется с помощью электролизера.The method of electrochemical fluorination involves passing through forced convection of a liquid mixture containing anhydrous hydrogen fluoride, a fluorinating organic compound, such as tripropylamine, at a temperature and pressure at which the mainly continuous liquid phase is maintained between the electrodes of the bipolar electrode packet. The bipolar electrode package contains a variety of mostly parallel electrodes made with a gap between them, made of electrically conductive material, such as nickel, substantially inert to anhydrous hydrogen fluoride and active when used as an anode for electrochemical fluorination; the package electrodes are electrically connected either in series or in series-parallel. A potential difference is imposed on the bipolar electrode packet, creating a direct current that causes the formation of a fluorinated organic compound, such as perfluorotripropylamine. The method is carried out using an electrolyzer.
