The Thermal Reaction Between Hydrogen and Oxygen II. The Third Explosion Limit

Abstract
The thermal high pressure explosion of the hydrogen‐oxygen mixture (``third explosion limit''), occurring near atmospheric pressure at 560°C, was studied. In the p—T diagram, a section of the limiting curve was determined. The effect of a KCl coat on a Pyrex surface was observed. The investigation of the third explosion limit does not lend itself to a decision between the competing theories of the thermal hydrogen‐oxygen reaction.
