They were: cobalt-tungsten carbide, which is used to make cutting and grinding tools, dyes, and other products for a broad spectrum of industries including mining; captafol, a fungicide banned in the United States in 1999; nitrotoluene
, a chemical used to make azo and other dyes, agricultural chemicals, pharmaceuticals, and other compounds; and certain inhalable glass wool fibers.
3] could be detected, they obtained nitrotoluene yields upto 80 % with a product distribution of o, m, p at 56, 4, 40.
Past literature on product distribution in toluene nitration has shown that the relative reactivity of o, m, p isomers of nitrotoluene is proportional to the electron availability at the active sites of the catalyst and the relative probability of their collision with a nitronium ion (Haouas et al.
Nitrotoluene destruction by UV-catalyzed Fenton reaction.
21] applied UV-assisted Fenton oxidation to degrade nitrotoluenes in water.
o- and p-Nitrotoluene
--The ortho- and para- isomers of nitrotoluene
are widely used in production of agricultural and rubber chemicals and a variety of dyes for cotton, wool, silk, leather, and paper, o-Nitrotoluene
yielded clear evidence of carcinogenic activity in all four sex/species groups, producing skin and mammary gland neoplasms in male and female rats and hemangiosarcomas and large intestine carcinomas in male and female mice.
