ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of resorcinol. It presents detailed information on the air analysis and analysis of aqueous and nonaqueous samples of resorcinol. Resorcinol is used in the manufacture of resins, dyes, and explosives. It is a white crystalline solid, which is soluble in water, alcohol and ether, and slightly soluble in chloroform. During the analysis of aqueous and nonaqueous samples of resorcinol, pH of aqueous samples is adjusted to below 2. Aqueous samples are extracted with methylene chloride and the extract is concentrated and analyzed by gas chromatography/mass spectrometry (GC/MS) or GC-FID. During the analysis of resorcinol, airborne particles are collected on a sorbent cartridge containing polyurethane foam. Deposited particles are extracted with methylene chloride.
