Ionic structure and sequence of ion formation in acetylene flames

The principal results of a study on the ionic composition of acetylene—air flames at low pressures are presented. The results are compared with data on the ion formation in flames of saturated hydrocarbons and oxygen-containing substances. It is shown that the laws of ion formation at the front and immediately in front of it are similar to those which have been established for other fuels, but are different for the low-temperature region.
