There are numerous methods proposed for determination of primary, secondary and tertiary amines. Most seem to be lengthy, inaccurate and unsuitable for small samples. Previous spectroscopic methods based on near‐infrared spectroscopy for determination of aliphatic and aromatic amines are not applicable for samples containing more than 10% nitrile. A simple method based on near‐infrared spectroscopy has been developed, and is presented, for determination of primary and secondary fatty aliphatic amines in the presence of 0–100% nitrile.
