Qualitative and quantitative determination fo trace amounts of aliphatic and aromatic amides and separation from ammonium impurities by molecular emission cavity analysis (MECA)

Department of Chemsitry, Colelge of sceince, University of Salahaddin, Arbil, Iraq
 
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.
