Aluminum metal reacts with various organic halides to give aluminum halides at a very slow rate initially. Then the aluminum halide in this reaction system autocatalytically accelerates the reaction itself. So that, it needs an induction period to give the aluminum halide actually. When aluminum or aluminum alloy was washed by various chlorinated hydrocarbon to remove the oily dirt from its surface, much trouble caused from corrosive degradation of aluminum surface or explosive reaction owing to the autocatalytic reaction has been reported.
The present study has been made to prevent this trouble and also to clarify the mechanism of the reaction.
First, several methods of measuring the induction period were examined, from which a new simplified method to measure it rapidly and accurately was proposed.
Then, many experiments were carried out to ascertain the factor which controls the induction period.
As a result, it was suggested that the rate of the halogen radical formation from organic halide by heating was one of the most important factors which had much to do with the induction period.
