Aniline is a simple compound, a benzene ring attached to an amine group. The synthetic dye industry grew rapidly as new aniline-based dyes were discovered in the late 1850s and 1860s. The formation of methemoglobin interferes with the oxygen-carrying capacity of the blood. They never contain any filler, which can reduce color potency. It does not readily evaporate at room temperature. In second and third vessels, potassium ferrocyanide (50 kg) and NaClO 3 (30 kg) are dissolved separately in 200 l of water each. A Madrid-based company imported denaturated rapeseed oil, dyed by aniline yellow to mark it as unsuitable for human consumption, to be used as a fuel in steel mills. By using different mordants, dyers can often obtain a variety of colors and shades from the same dye, as many mordants not only fix the natural dye compounds to the fibre, but can also modify the final dye color.
