Abstract

Patente de Invenção: <B>"RECUPERAçãO DE COMPOSTO HIDROXI-AROMáTICO DE SOLUçõES DE EXTRATOS AQUOSOS"<D>. Método para recuperar eficientemente um composto hidroxi-aromático da corrente de extrato aquoso das misturas de reações de carbonato di-arila, compreendendo contatar os extratos aquosos com um solvente adequado, preferivelmente carbonato di-fenila ou anisol. A corrente aquosa pode então ser posteriormente reciclada ou recuperada, e o composto hidroxi-aromático isolado do solvente para disposição ou uso posterior.
