A RESEARCH PROGRAM FOR UNDERSTANDING THE MECHANISMS OF FLAME INHIBITION

Abstract

The effects of inhibitors on the diborane-air and pentaborane-air reactions were studied by measuring flame speeds of borane-air-inhibitor mixtures at low pressures, and by the shock tube technique. The best flame inhibitors were the hydrocarbons and halogenated hydrocarbons which had been found earlier to inhibit hydrogen air flames. Some of these inhibitors were ineffective in lengthening ignition delays in the shock tube, indicating that a different mechanism may apply in flame propagation than in shock ignition. Detailed kinetic calculations of the effects of CH4, C2H4, CF3Br and C2F4Br2 on the hydrogen-oxygen reaction have yielded values for the rate constants of the reactions whereby these inhibitors remove H atoms from the reacting system.
