Highly Selective Cyclohexane Oxidation Catalyzed by Ferrocene in Ionic Liquid Medium (IMAGE)
Caption
Polyamide (PA) 6 is widely used in several industries and therefore economically very important. In its current industrial production process, first KA oil (a mixture of cyclohexanol and cyclohexanone) is obtained from cyclohexane ineffective oxidation (ca. 4 percent cyclohexane conversion to assure a reasonable selectivity, ca. 85 percent), and then converted, at high pressure and 150 ºC and in the presence of copper and chromium oxides, to cyclohexanone which is then used to form caprolactam, the monomer for produce PA 6.
