Adipic acid
Cyclohexanol / cyclohexanone oxidation with nitric acid. Minimum waste
Dicarboxylic acid
Proprietary oxidation of cyclohexanol and cyclohexanol–cyclohexanone mixtures with nitric acid. Two stages: producing the cyclohexanol-cyclohexanone mix from benzene, then oxidising it into the final product. Low feedstock and auxiliaries consumption, reliable and safe reactor section, effective use of reaction heat, stable crystallisation and minimal environmental footprint.
