Separate Quantitative Determination of Primary, Secondary, and Tertiary Aromatic Amines

摘要

For determining primary, secondary, and tertiary aromatic amines in one mixture, a method was developed. In it, the primary amine is first titrated in the presence of tropeolin 00, the secondary amine is titrated in the presence of methyl orange or red, and finally the tertiary amine is titrated in the presence of phenol in methylene blue solution. Details of the method and results of some analyses are given. (ERA citation 03:015550)
