As a preliminary experiment for elucidation of the reaction mechanism of quinone-activated carbon treatment, reaction was carried out of p-benzoquinone, α-naphtho-quinone, and chloranil with 25 kinds of nitrogen-containing organic compounds, including aliphatic and aromatic amines, nitrogen-containing heterocyclic compounds, amino acids, and proteins. Examinations were made on the isolation of products by adsorption on actuated carbon and ddsorption from this activated carbon. As indicated in Table I, the results of these experiments showed that nitrogen-containing organic compounds in general, with the exception of a few, reacted easily with quinones and that the reaction products are separated by adsorption on activated carbon. It was found that a nitrogen-containing organic compounds are liberated from the adsorbed carbon according to the nature of such compounds or to reaction conditions with a quinone. The appropriateness of this quinone-activated carbon treatment was confirmed and the experiments made some important suggestions for elucidation of this reaction mechanism.
