	Aniline - Wikipedia, the free encyclopedia
		In commerce three brands of aniline are distinguished—aniline oil for blue, which is pure aniline; aniline oil for red, a mixture of equimolecular quantities of aniline and ortho- and para-toluidines; and aniline oil for safranine, which contains aniline and ortho-toluidine, and is obtained from the distillate (échappés) of the fuchsine fusion.
		Aniline and its ring-substituted derivatives react with nitrous acid to form diazonium salts.
		Oil mixtures containing rapeseed oil denatured with aniline have been clearly linked by epidemiological and analytic chemical studies to the toxic oil syndrome that hit Spain in the spring and summer of 1981, in which 20,000 became acutely ill, 12,000 were hospitalized, and more than 350 died in the first year of the epidemic.

	ANILINE (AMINOBENZENE)
		Commercial aniline is obtained from nitrobenzene which is prepared from benzene with nitric acid by electrophilic substitution reaction or from chlorobenzene by heating with ammonia in the presence of copper catalyst.
		Aniline is processed to produce a series of compounds being used in the rubber industry, e.g.
		Anilide is an amide derived from aniline by substitution of an acyl group for the hydrogen of NH Acetanilide is thus obtained from acetic acid and aniline.

	ANILINE (Site not responding. Last check: 2007-10-06)
		Aniline is a blood toxin, causing hemoglobin to convert to methemoglobin, resulting in cyanosis.
		A NIOSH study reported an excess bladder cancer risk in workers exposed to aniline in combination with other dyestuffs and intermediates, although it is not clear which of these materials, or combinations, were responsible for the higher incidence of bladder cancer.
		Based on the results of this study, historical epidemiology evidence which shows no correlation of pure aniline with bladder cancer, and experimental test results, it was concluded that aniline, most likely, is not responsible for the increased incidence of bladder tumors in the NIOSH study.

	Aniline [factsheet]
		* Airborne exposure to aniline may occur from breathing contaminated air, from smoking tobacco or proximity to someone who is smoking, or from being near industrial sources that use large quantities of aniline.
		(m g/L) EPA estimates that, if an individual were to ingest water containing aniline at 6 m g/L* over his or her entire lifetime, that person would theoretically have no more than a one-in-a-million increased chance of developing cancer as a direct result of drinking water containing this chemical.
		* Aniline is predominantly used as a chemical intermediate for the dye, agricultural, polymer, and rubber industries.

		The figures in this page show the signatures of ac and dc potentiodynamic responses acquired with potentiodynamic electrochemical impedance spectroscopy in cathodic and anodic scans in the initial and most nonstationary stages of aniline electropolymerisation on gold.
		The dc part of the response is represented by the voltammogram in the transparent front facet of the parallelepiped.
		Analysis of the ac response dependence on frequency gives parameters of the underlying processes as functions of variable potential and this enables simultaneous investigation of various interrelated processes (see the article).
