Ninhydrin反応の研究 (第6報)

第2級アミンのNinhydrin反応

抄録

Since formaldehyde is formed during the ninhydrin reaction of ephedrine, adrenaline, sarcosine, and methylbenzylamine, the ninhydrin reaction of these secondary amines was assumed to occur by the liberation of the primary amine. It follows, therefore, that the rate of coloration of such secondary amines is dependent on the ease or difficulty of the liberation of the primary amines.
