Abstract

The fluorination of elementary substances and inorganic and organic compounds with elementary fluorine is accompanied by high heat release (of about hundreds of kilojoules per mol of fluorine), which determines the high probability of their implementation in the unsteady-state temperature mode (combustion or thermal explosion mode) when the temperature of the process products is close to adiabatic, and a significant part of the released heat is removed from the obtained substances outside the reaction zone. If target fluorides are present in the thermodynamically equilibrium mixture of substances in an element system that contains fluorine at a temperature close to the adiabatic temperature, fluorination in the combustion mode is successfully used in industry. Otherwise, it is reasonable to perform fluorination in the steady-state (close to isothermal) temperature mode by removing the heat of the reaction from the reacting mixture directly in the reaction zone. This publication considers the efficiency of application of the steady- and unsteady-state temperature modes in the fluorination of various substances with elementary fluorine.

使用元素氟作为氟化剂的热力学方面

摘要

单质和无机和有机化合物与单质氟的氟化伴随着高放热（每摩尔氟约数百千焦），这决定了它们在非稳态温度模式（燃烧或热爆炸模式）当过程产物的温度接近绝热时，释放的热量的很大一部分从反应区外的所得物质中去除。如果目标氟化物存在于温度接近绝热温度的含氟元素系统的热力学平衡物质混合物中，则燃烧模式下的氟化在工业中得到成功应用。除此以外，通过在反应区直接从反应混合物中去除反应热，在稳态（接近等温）温度模式下进行氟化是合理的。该出版物考虑了稳态和非稳态温度模式在各种物质与元素氟的氟化中的应用效率。
