This material was tested for solvent-free catalytic oxidation of monochlorotoluene under chosen conditions. The result shows that V-Mo-O/SiO <sub>2 </sub>is effective catalysts, exhibiting conversion of monochlorotoluene and selectivity monochloromaleic anhydride 75–85%, 24–32% respectively. Furthermore, the catalyst can be easily recovered and reused for 20-25 hours without a significant loss in its activity and selectivity. The oxidation rate and direction determined by the temperature (315-450 <sup>0 </sup>C), proportions between the reagents (1:1–1:15 mol/l), bond dissociation energies, the effects of active components of catalyst and contact time.  </p>}, number={3}, publisher={Turkish Chemical Society}
