Abstract
The use of chlorofluorocarbons (CFCs) alternatives can avoid the use of ozone-depleting substances and reduce greenhouse gas emissions. The gas-phase fluorine-chlorine exchange reaction belongs to Swartz reaction under catalysis of fluorides, which is mainly used for the synthesis of C1~C6 CFCs substitutes or their intermediates as well as a series of heteroatomic fluorides used in important fields such as lithium batteries and fluorine-containing pharmaceuticals, showing the characteristics of green, efficiency, and easy to achieve large-scale production. The reaction mechanism, fluorination catalysts, and synthetic processes of CFCs substitutes or intermediates by gas-phase fluorine-chlorine exchange were reviewed. The future development trend of gas-phase fluorine-chlorine exchange was discussed, and it was proposed that the future study should focus on the theoretical basis of chromium-based catalysts for gas-phase fluorine-chlorine exchange reactions, development of gas-phase fluorine-chlorine exchange process technologies for high-carbon chloroalkanes, and the application of gas-phase fluorine-chlorine exchange technology in new energy and fluorine-containing pharmaceutical fields.
