“…The marked differences which occurred in the explosive range might be explained by the fact that the kinetics of the deuterium-oxygen reaction is slower than the hydrogen-oxygen reaction (3)(4)(5). Experimental and theoretical properties of dry knallgas and heavy knallgas were compared recently (2). Even though the measured stable detonation pressures for heavy knallgas as reported by this investigation were subideal at low pressures (less than 2 to 3 atm.…”
