ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of aniline. It presents detailed information on the air analysis and analysis of aqueous and nonaqueous samples of aniline. Aniline is used in the manufacture of dyes, varnishes, resins, pharmaceuticals, and photographic chemicals. It is colorless oily liquid with characteristic odor, soluble in water, weakly alkaline, and readily mixes with most organic solvents. During the analysis of aqueous and nonaqueous samples of aniline, aqueous samples are repeatedly extracted with methylene chloride. During the air analysis of aniline, air is drawn through a solid sorbent tube containing silica gel. The analyte is desorbed into 95" ethanol in an ultrasonic bath and determined by gas chromatography-flame ionization detector or gas chromatography-nitrogen-specific detector (NIOSH Method).
