ABSTRACT
Alphatic amides (formamide 99.5%, and acetamide 97%) an an aromatic amide (benzamide 98.5%) were determined qualitatively and quantitatively at trace levels bases in acid hydrolysis. Ammonia gas was detected by measuring the white band emission using thermal chemiluminescence in a cool hydrogen diffusion flame. Amides were detrmined quantitaively by hydrolysis with potasium hydroxide. Separation and identification of ammonium nitrogen present as impurities in amide were also studied.
