Notes:

Gas phase selective oxidation of chlorotoluene’s on vanadium oxide-based catalysts

cofriendly disposal and conversion of persistent chloro-

organic pollutants is one of the important issues which

pushed the chloro-hydrocarbon chemistry into the focus of

considerable debate and research topic. It’s known, modified

oxovanadium catalysts are widely used in the heterogeneous

catalytic oxidation reactions. Moreover, maleic anhydride

and its chloro-substituted analogues have wide apply in

many industries, such as paints, pharmacy additives etc.

The common feature of having one or more covalent bound

chlorine atoms, these compounds show a complex diversity

of behavior that is primarily characterized by their aromatic

character and the presence of other functional groups.

Nevertheless, the introduction of chlorine atom(s) into

desired products significantly influences its physicochemical

and biochemical properties. From this point of view, the

present paper is devoted to find a better performing catalyst

for the selective oxidation of chloroaromatic hydrocarbons.

Catalytic systems based on salt sand oxides of V, Mo, Sb, P were

prepared by co-precipitation, impregnation and mechanical-

chemical shifting and characterized via Scanning electron

microscope, X-ray diffraction, Thermal analysis, N

adsorption-

desorption methods. Elemental analysis is used to determine

quantitativeelementalcontentofcatalysts.Ananalysisofreagent

and product composition was carried out using Agilent 7820A

GC equipped a flame ionization detector (FID) and Hp5 column.

Selective oxidation processes of chlorotoluene’s investigated

both on a fixed bed and fluid-bed layer of catalyst. Although the

process of heterogeneous catalytic oxidation of chlorotoluene’s

took place with a higher conversion in a fixed bed but it

showed higher selectivity fluid-bed layer of catalyst was found.
