Title: On the Specific Coloration of the Benzylamine Type Compounds in the Ninhydrin Color Reaction. I
Abstract: The specific coloration of the benzylamine type compounds in the ninhydrin color reaction is extended to other kinds of compounds. Alloxan resembles ninhydrin in its behaviour as reagent. The fact that the specific coloration reaction seems to be common to the benzylamine type compounds, is verified. However a few exceptions are observed as in the case of benzylaniline (17) and p-dimethylaminobenzylamine (18). The fact that the color change of these compounds in the usual paper chromatography is due to moisture in the air, is confirmed.
