ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of epichlorohydrin. It presents detailed information on the air analysis and analysis of aqueous and nonaqueous samples of epichlorohydrin. Epichlorohydrin is used to make epoxy resins, adhesives, surfactants, and plasticizers, and also as a solvent for gums, resins, and paints. It is colorless liquid with chloroform-like odor, moderately soluble in water, soluble in most organic solvents, moderately toxic, carcinogenic, and a strong irritant. During the analysis of aqueous and nonaqueous samples of epichlorohydrin, aqueous samples are subjected to the purge and trap concentration method. The analyte is thermally desorbed from the trap and swept onto a gas chromatography (GC) column for separation from other volatile substances and detected by hall electrolytic conductivity detector (HECD), electron capture detector (ECD), or a mass spectrometer. During the air analysis of the epichlorohydrin, samples are adsorbed over coconut shell charcoal.
