Limiting phenomena in the reaction of fluorine with hydrogen

Reactions involving energy branching and deceleration by the end product were studied using as an example the reaction of fluorine with hydrogen. It has been shown that for such reactions, entrance into the autoignition region determined by static conditions (reagent concentration, pressure, and temperature) due to variation in the pressure of the mixture may be or may not be accompanied by mixture autoignition. The parameter determining the behavior of a particular mixture is the rate of variation in the mixture pressure. A process of fast (in the range of seconds) preparation of fluorocarbon mixtures with minimal yield of hydrogen fluoride is substantiated.
