The retarding effect (RE) of various organic reagents on the reaction beween 1, 1, 1-trichloroethane (CCl3·CH3) and aluminum was investigated by measuring the induction period of the reaction. In the previous paper, it was confirmed that the RE of compounds having two functional groups increased 5-100 times over that of compounds having one functional group. However, contrary to expectation, some dihydric and trihydric phenols, diamides and imides, which do not dissolve in CCl3CH3, had no effect of RE.In this paper, we tried to dissolve these insoluble organic reagents in CCl3CH3 by adding a solvent, and then examined whether these organic reagents had a large RE or not. The results are summarized as follows: 1) polyphenols (1, 3-dihydroxybenzene and 1, 3, 5-trihydroxybenzene and 1, 2, 3-trihydroxybenzene), diamides (succinic acid diamide and phthalic acid diamide) and imides (succinimide and phthalimide) could be dissolved in CCl3CH3 by using ethyl alcohol or acetone as a solvent. The RE of these organic reagents was found to be extremely large. 2) when two species of soluble organic reagents having different functional group were added in CCl3CH3, the RE was larger than that of one species, but smaller than that of other species. The synergistic action, that is, the phenomenon that the RE when two species of organic reagents were used simultaneously becomes larger than those of respective reagents, was not observed. Accordingly, when an insoluble organic reagent and a solvent were also added simultaneously, it is concluded that there was no synergistic action.
