The reaction between aluminum, in the form of flat plates, and chlorine was investigated in a flow system at temperatures from 500° to 650°F. Gaseous aluminum chloride was the reaction product at these temperatures. At 500°F. the reaction proceeded by pitting, and the rate appeared to be chemically controlled. The reaction mechanism changed at higher temperatures to give a smooth reacted surface, and the reaction rate was found to be dependent upon both mass transport and kinetic parameters. The method proposed by Rosner for calculating mass transport‐dependent reaction rates was found to correlate both average and local rate data and was used to obtain estimates of the kinetic parameters for the heterogeneous surface reaction.
