Abstract
Process of fluorination of perfluorodecalin and perfluoro-1,3-dimethyl cyclohexane with fluorine in a gas-fluid reactor with a high-speed stirrer was experimentally studied. It was shown that the fluorination reaction rate decreases in the process of fluorine treatment for 2 h and then stabilizes, being at 80°C 0.5 and 1.3 µg s–1 L–1 for perfluoro-1,3-dimethylcyclohexane and perfluorodecalin, respectively. A comparison of the fluorination rates of perfluorodecalin, perfluoro-1,3-dimethylcyclohexane, and fozhalin (main substance perfluorotripropylamine) made it possible to formulate recommendations on choosing a perfluorinated fluid as a medium for studying the fluorination of organic compounds with fluorine in a gas-fluid reactor, for which the loss of fluorine in the destructive fluorination of a fluid will be on the order of 10−1%.
