Abstract : The mechanisms for the formation of positive ions in aliphatic hydrocarbon flames are the same as that of electrons and the discussion is centered around positive ions. Probable chain reactions and mechanism for the formation of the most abundant positive ion are summarized. A steady state analysis of reactions reveals a number of important conditions that must be fulfilled for the most abundant ion formation. Approximate values for the maximum and minimum concentrations of the most abundant ion with respect to oxygen are obtained. A semi-theoretical method is used to calculate the concentration of the most abundant ion in hydrocarbon-oxygen or hydrocarbon-air flames. Experimental studies were performed on the effect of ultraviolet light on ion concentration in flames. Research has also been started on the effect of the degree of unsaturation, state of oxidation, and length of the carbon chain on ionization of various hydrocarbons in a hydrogen-oxygen flame.
