Monographs in Organic Functional Group Analysis, Volume 4: The Determination of Organic Peroxides focuses on the analytical chemistry of organic peroxides. The monograph first offers information on the compositions, properties, and reactions of lipid peroxides, polymers, and petrochemicals. The text then reviews the iodometric methods, including choice of solvents, reaction conditions, and titration with thiosulfate. The ferrous ion methods are also discussed. Considerations include choice of reagents and solvents and titration with titanous, dichromate, and mercurous ions. The book also focuses on titrimetric methods, including arsenious, stannous, and titanous methods, titration with anions, and sulfides and mercaptans. Numerical representations are provided. The text puts emphasis on colorimetric and polarographic methods. Polarographic techniques for peroxides; nature and concentration of peroxides; leuco base of methylene blue; and ferrous ions are described. The book also discusses paper, thin-layer, and gas chromatography. The monograph is an important guide for readers interested in the analytical chemistry of organic peroxides.
