Burning Velocity in Mixtures of Cyanogen or Hydrogen Cyanide With Oxygen

Abstract

Burning velocity, flame temperature and thickness of the reaction zone have been measured in different cyanogen/oxygen/nitrogen and hydrogen cyanide/oxygen/ nitrogen mixtures. Some measurements have been made also on CaNa/Oz/Na mixtures with addition of hydrogen. Kinetical parameters have been derived: activation energy and reaction order. A kinetical mechanism has been proposed which is based on observations made by others in some studies using the technique of flash photolysis. The experimental study of laminar flame propagation in flammable mixtures involves the determination of three characteristic magnitudes: burning velocity, maximum flame temperature and thickness of the flame reaction zone. The methods which were applied in this work have been described in a previous publication [a.(*)
