I just work on the separation of alkanolamides using HPLC. There is a reference about this. But I have no access on it.

Quantitative Monitoring of Stearic Acid Monoalkanolamide Syntheses by HPLC
Journal of Liquid Chromatography
Volume 9, Issue 1, 1986

Are there anyone could give me some suggestion or send me a copy of this? Many thanks in advance. :)
