Selective liquid phase air oxidation of toluene catalysed by composite catalytic system

   
   

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.

Присытствыющий вымысел обеспечивает улучшенный процесс для продукции бензальдегида с селективностью 40-50% каталитической жидкостной оксидацией воздуха участка толуола использующ составную каталитическую систему состоя из солей утюга, кобальта, марганца, молибдена или никеля как recyclable катализатор, солей марганца или меди как recyclable бромид чо-katalizatora и кобальта, бромид натрия, хлорид натрия и бромид цинка как promoter.
