N2 - Industrial residues formed in the industrial production of benzoic acid
by cobalt-catalyzed oxidation of toluene are traditionally disposed as
waste materials and often burnt or buried. It therefore may become a
significant source of environmental pollution. In this report, we
describe simple techniques to obtain high value conjugated aromatic
compounds, including 9-fluorenone, 6H-benzo[c]chromen-6-one,
biphenyl-3-carboxylic acid, and biphenyl-4-carboxylic acid, from benzoic
acid industrial residue using inexpensive alkalis and acids. The
separation methods involve simple and mild procedures with high economic
effectiveness and low environmental contamination.
