Benzylation of chlorobenzene over M-ferrites M 2+ Fe3+O4 (M2+= Fe2+Zn2+, Ni2+, Cd2+, V2+)‎

Abstract EN

A series of M2+Fe3+O4 (M2+represent Fe2+,Zn2+,Ni2+,Cd2+,V2+) ferrites were synthesized by co-precipitation of M-Ferrites normally soluble under controlled conditions.

The synthesized ferrites were used as a catalyst to benzylatechlorobenzene usingbenzylchloride.

The effects of some parameters, such as temperature, a molar ratio, type; amount, reusabilitytest and leaching test of catalyst were followed.

The optimum conditions appliedwere (80ºC, 1:15 for benzylchloride/ chlorobenzene, 0.1g as weight of catalyst and Fe- Fer.as type of catalyst).

The reaction products were invistigatedusing GC chromatograph equipped with FID detector.

The results showed that when M-ferrites were used for benzylation of chlorobenzene, very high efficient catalytic activity about 90% for the conversion of chlorobenzene tochlorodiphenyl methane (CDPM) was obtained.

The synthesized M-Ferrites were successfully used as heterogeneous and magnetically recoverable catalyststo benzylationreaction.

Thebenzylation reaction was observedas not toproceed in the absence of M- ferrite catalysts.
