Аннотация:The reaction of 1,1,1,2-tetrafl uoroethane with fl uorine in a gas–liquid reactor with a high-speed stirrer and with perfl uorodecalin or perfl uoro-1,3-dimethylcyclohexane as a liquid phase occurs as hydrogen substitution without noticeable cleavage of С–С bonds, yielding penta- and hexafl uoroethane. The fl uorination of methane in perfl uorodecalin under the same conditions yields, depending on the methane and fl uorine concentrations in their mixtures with an inert gas, products of successive hydrogen substitution by fl uorine when the reaction occurs in approximately isothermal mode and products corresponding to the thermodynamic equilibrium when the reaction occurs in the mode of gas-phase diffusion combustion on the gas bubble scale.
