Abstract
To prevent the accidental explosion in the reaction between aluminum and various organic halides which was reported in the previous paper, ethers, esters, nitriles, amines and acid amides were utilized as inhibitors of the reaction between aluminum particles and boiling carbon tetrachloride. It was found that they were effective to prolong the induction time of reaction.
It seemed that the inhibitors reacted preferentially with chlorine radical resulting in the extinction of activity to start the chain reaction, or formed some stable additional compound with aluminum chloride to give subsequent destructive effect on its catalytic activity. Inhibiting power of these organic compounds was considered to indicate the measure of the effect of delaying the induction period.
From these results, relation between kind of functional group of organic substances and each inhibiting power was further clarified. The inhibiting power appeared in the reaction were discussed in connection with molecular structure of organic compound and its adsorptive property on the aluminum surface.
