Abstract
"PROCESSO PARA PURIFICAR CAPROLACTAMAS". A invenção relaciona-se a um processo para purificar caprolactama, o referido processo compreendendo (a) submeter a caprolactama a uma hidrogenação pelo tratamento da caprolactama com hidrogênio na presença de um catalisador de hidrogenação contendo níquel heterogêneo, (b) destilar pelo menos uma porção da caprolactama hidrogenada em uma coluna de destilação contendo níquel em uma quantidade suficientemente baixa de forma que <30>PAN~ Ni~ <243> 3, onde <30>PAN~ Ni~ = <30>PAN - <30>PAN~ Ni=0~, <30>PAN = aumento do número de PAN de caprolactama durante a destilação, <30>PAN~ Ni=0~ = aumento do número de PAN de caprolactama durante destilação sob as mesmas condições em uma coluna de destilação livre de níquel. O níquel é removido da solução de caprolactama antes da etapa de destilação.
