Abstract

"PROCESSO PARA A PRODUçãO DE CICLOEXANONA OXIMA". A invenção refere-se a um processo para a produção de cicloexanona oxima, no qual um meio de reação aquoso contendo fosfato realiza um ciclo a partir de uma zona de síntese de hidroxilamónio para uma zona de síntese de cicloexanona oxima e de volta para a zona de síntese de hidroxilamónio, em que o hidroxilamónio da zona de síntese de hidroxilamónio é formado por redução catalítica de nitrato com hidrogênio, e em que o hidroxilamónio da zona de síntese de cicloexanona oxima é reagido com a cicloexanona para formar a cicloexanona oxima, onde a concentração de hidroxilamónio no meio de reação aquoso que entra na zona de síntese de cicloexanona oxima é maior do que 1,0 mol/l.
