Abstract

"MéTODOS E DISPOSITIVOS PARA REMOVER áCIDO ACéTICO DE CICLO-HEXANO NA PRODUçãO DE áCIDO ADìPICO" Esta invenção refere-se a métodos e dispositivos para remover ácido acético de ciclo-hexano na oxidação direta de ciclo-hexano a ácido adípico, especialmente depois de reciclar o catalisador que é precipitado pela introdução de ciclo-hexano adicional. A remoção do ácido acético é conduzida, de preferência, pelo uso de quantidades bem pequenas de água de lavagem em um extrator de um a três estágios. Um reator de dois estágios é preferível por ser mais eficiente.
