  Author(s): Rehan KhanRehan Khan
  
  Phthalic anhydride is manufactured by the partial oxidation of ortho xylene in the presence of V2O5/TiO2 catalyst. In the residue, maleic acid, benzoic acid (BA), telluric acid and traces of other organic compounds are present in the by-product stream. There is almost 60% of (BA) in the residue sample, which compels to recover the tremendous amount of (BA), as it is of great importance. The waste stream is in the form of slurry at high temperature and is solidified at room temperature. Benzoic acid was selectively removed from the solid waste of Phthalic anhydride production industry by the processes associated with less intensive parameters as compare to the extraction techniques achieved by, pressurized hot water, supercritical CO2 extraction, where the required parameters are highly intensive. The separation has been performed by using physical and chemical techniques. .. View More»
