The inhibiting action of various organic reagents on the reaction between 1, 1, 1-trichloroethane (CCl3CH3) and aluminum was investigated by the degree to which the induction period of the reaction was prolonged. The relationship between the chemical constitution of the reagents and the inhibiting action was also discussed.
The results are summarized as follows: 1) From the standpoint of the functional radicals of the reagents the inhibiting action was stronger in the order of ether<ester<alcohol<amine<keton<nitrile<amide. 2) An increase in the carbon count in the alkyl radical of aliphatic compounds did not contribute to greater inhibiting action. 3) The inhibiting action of ether and alcohol isomers was stronger in the order of n-<iso-<sec-<tert- but that of amine isomers was stronger in the reverse order. 4) In a single functional radical an increase in the inhibiting action was not observed even if the aliphatic compound was converted into the benzene compound. 5) The inhibiting action of compounds having two functional radicals (dihydric alcohol diamine diketon dinitrile and dinitro compounds) was stronger than for those having a single functional radical but some dihydric and trihydric phenols and diamides, which are insoluble in CCl3CH3 had no effect on the inhibiting action.
