A method for the determination of primary aliphatic amines in the presence of secondary and tertiary amines is described. The primary amine is reacted wit ha complexing reagent containing cupric chloride, salicylaldehyde and triethanolamine. The copper complex formed is extracted into 10% hexanol in toluene. The amount of copper in the toluene layer is determined by atomic absorption spectroscopy. This is a measure of the primary amine in the sample. The method can be successfulyl applied to both monoamines and diamines as well as an amino alcohol. Data for the analysis is + 0.05% at the 2% level and below. Ammonia, if present, interferes, but a correction can be made. Secondary and tertiary amines do not interfere even when present at the 98% level.
