Abstract
Patente de Invenção: <B>"PROCESSO DE PURIFICAçãO POR EXTRAçãO DE UM MEIO LìQUIDO"<D>. Processo de purificação por extração de pelo menos uma substância a ser isolada a partir de um meio líquido, compreendendo uma adição a este de um composto orgânico, arrastável por um vapor que apresenta uma molécula de caráter ácido-básico no sentido de Lewis, devido a pelo menos um átomo de N, O e/ou S, formando um dos locais ativos providos de um doublet eletrónico livre, esses(s) doublet(s) estando em ressonância com pelo menos um outro doublet apresentado pela molécula, essa adição sendo feita em uma quantidade suficiente para dar origem a um produto de uma reação equilibrada entre o composto orgânico e a(s) substância(s) pelo menos uma substância a ser isolada, e para provocar uma precipitação desse produto de reação equilibrada, uma filtração do precipitado e um arrastamento no vapor do composto orgânico a partir do precipitado, com coleta da substância a ser isolada sob a forma purificada.
