1)The absorption spectra were measured of the color reaction between each of the fourteen 1-substituted 2, 4, 6-trinitrobenzene compounds and acetone in the presence of alkali. The typical absorption curves are shown in Fig. 1. 2) Phenyl picrate and picryl chloride were selected from among these nitro compounds as examples. When the colored substances, formed by the reaction between each of these two compounds and acetone in alkaline medium, were acidified in the presence of hydrogen peroxide, the trinitrobenzene compounds (III) and (VI) were respectively formed. From this result, the structures (II and V) of these colored substances were determined. 3) The colored substances derived from 1-substituted 2, 4, 6-trinitrobenzene compounds of type A were assumed to form principally the structure of (XVI), while the compounds of type B give both structures of (XVI) (mainly) and (XVII).
