I would like to ask everyone: Are there any organic fluorinated liquid compounds that contain both carbonyl groups and ether functional groups? What substances are generally used for synthesis? What to use as a catalyst? The general formula for such substances is as follows: Rf1- C-CH2-O-Rf2, where both alkyl groups Rf1- and Rf2- contain a large number of fluorine atoms (F). Therefore, it is a long-chain fluorinated organic liquid compound. Its boiling point is 120°C, its thermal conductivity is 0.067 W/(m·K), and its atmospheric lifetime is estimated to be 0.
Yes, such organic fluorine-containing liquid compounds that possess both carbonyl and ether functional groups do exist. A common synthetic method is to prepare it through the fluorination of alcohols. The specific steps are as follows: 1. First, the organic compound containing carbonyl and ether functional groups is reacted with hydrofluoric acid to replace the oxygen atoms in the hydroxyl or ether groups with fluorine atoms ； 2. Then, use a base to neutralize the remaining hydrofluoric acid to prevent further reactions ； 3. Finally, the target compound is purified by methods such as distillation. In this reaction, hydrofluoric acid acts as a catalyst, enabling the fluorination of hydroxyl or ether groups. Furthermore, the reaction conditions also need to be properly controlled, such as temperature and reaction time, to ensure the selectivity and yield of the reaction. The organofluorine liquid compounds synthesized by the above method have the general formula Rf1- C-CH2-O-Rf2, where Rf1- and Rf2- are long-chain alkyl groups containing a large number of fluorine atoms. Its boiling point is generally high, around 120°C, its thermal conductivity is relatively low, and its atmospheric lifetime is estimated to be 0. .
