Stability and Nonexplosive Hydrogen Fluoride Production in Atmospheric-Pressure Hydrogen-Oxygen-Fluorine Mixtures

摘要

The behavior of atmospheric-pressure mixtures of H2, O2, and F2 at ambient temperatures was studied to determine conditions under which the reagents can be combined nonexplosively. An HF probe laser monitored the formation of HF during the mixing process and for the following 30 min, under conditions where < 5% of the reagents had disappeared. Hydrogen fluoride formed relatively "promptly" during mixing and at an essentially constant rate thereafter. Evidence is presented that heterogeneous reaction steps significantly influence the slow deterioration of prepared mixtures.
