The present invention provides an improved process for the production of benzaldehyde
with 40-50% selectivity by the catalytic liquid phase air oxidation of toluene using a
composite catalytic system comprising salts of iron, cobalt, manganese, molybdenum or
nickel as recyclable catalyst, salts of manganese or copper as recyclable co-catalyst and
cobalt bromide, sodium bromide, sodium chloride and zinc bromide as promoter.
