Abstract : A scheme for the chemical analysis of smokes and flares (yellow smoke mixture) consists of an aqueous extraction of KClO3, sugar, and NaHCO3. Sucrose is obtained by inverting it to fructose and glucose, which are reducing monosaccharides, these are reacted with Fehling's Solution to precipitate Cu2O, which is weighed quantitatively. KClO3 is reduced to the Cl ion and precipitated as AgCl. NaHCO3 is reacted with an excess of HCl and the excess is back titrated with NaOH. Indanthrene Golden Yellow GK and benzanthrone are determined spectrophotometrically. Silocel and Cabosil, which are both SiO2, are reported as total SiO2. After the water soluble chemicals are removed, the remaining material which is SiO2 is ignited to constant weight. (Author)
