Abstract : An evaluation was made on five analytical methods for the determination of chloroacetophenone (CN) when disseminated from an encapsulated form or as an intimate mix in standard pyrotechnic-mix systems. The descending order of systems yielding specificity and accuracy in the 1-microgram/ml range was modified DB3>m-dinitrobenzene>ultraviolet (UV) measurement. The latter method was the least accurate because some CN decomposition products (acetophenone and munitions debris entered additively at the analytical wavelengths. A DB3 test (1-microgram/ml), and infrared method, and a gas-liquid-chromatography method for the estimation of CN disseminates in the range of 1 mg/ml are described. Low yields (5%) from standard CN grenades are not caused by the ambient storage decomposition of CN, but rather by the deterioration of CN during munition functioning and by the poor dissemination efficiency of the pyrotechnic cake.
