Abstract

"PROCESSO PARA A PREPARAçãO DE OXIMA DE CICLOEXANONA". A invenção se refere a um processo para a produção de oxima de cicloexanona, no qual um meio reacional aquoso contendo fosfato é um submetido a um ciclo de uma zona de síntese de hidroxilamónio para uma zona de síntese de oxima de cicloexanona e de volta para a zona de síntese de hidroxilamónio, em cuja zona de síntese de hidroxilamónio, hidroxilamónio é formado por redução catalítica de nitrato com hidrogênio, e em cuja zona de síntese de oxima de cicloexanona, hidroxilamónio é reagido com cicloexanona para formar oxima de cicloexanona, a cicloexanona e um solvente orgânico sendo alimentados à zona de síntese de oxima de cicloexanona, um meio orgânico compreendendo o solvente orgânico e a oxima de cicloexanona sendo retirado da zona de síntese de oxima de cicloexanona, caracterizado pelo fato de que a relação f~ h~/f~ c~ < 1,00, em que f~ h~ representa a quantidade molar de hidroxilamónio alimentado à zona de síntese de oxima de cicloexanona por unidade de tempo (em mol/s) e f~ c~ representa a quantidade molar de cicloexanona alimentada à zona de síntese de oxima de cicloexanona por unidade de tempo (em mol/s).
