Aluminum (Al) is violently dissolved in 1, 1, 1-trichloroethane (CCl3CH3) once the induction period has passed. In the present paper, the dissolution rate of Al in CCl3CH3 was investigated.<br>It was found that: 1) The dissolution reaction of Al in CCl3CH3 was zero-order, as in such liquid organic halides as carbon tetrachloride (CCl4), trichloroethylene and tetrachloroethane. 2) At temperatures ranging from room temperature to boiling point (347K) of CCl3CH3, the activation energy for the dissolution of Al in CCl3 CH3 was smaller than that in CCl4 reported previously, indicating that the reactivity of CCl3CH3 to Al is higher than that of CCl4. 3) When such organic reagents as methyl alcohol, n-buthyl alcohol, sec-buthyl amine, etc., were added as inhibitors in CCl3CH3, an increase occurred in the induction period of the reaction but there was no effect on the dissolution rate of Al. 4) CCl3CH3 solution to which AlCl3 was added exhibited electrical conductivity, and based of this observation, the dissolution mechanism could be well explained by the ionic reaction. 5) Dissolution of Al was accompanied by the generation of a large quantity of hydrogen chloride, so it is thought that the dissolution rate of Al was greatly increased by a number of chain reactions.
