Abstract

Método de purificacion por extraccion por lo menos de una substancia por aislar de un medio líquido, que incluye una adicion a éste de un compuesto orgánico, arrastrable por un vapor, que tiene una molécula de naturaleza ácido-básica en el sentido de Lewis debido por lo menos a un átomo de N, O y/o S que forma uno o más sitios activos provistos de un par libre de electrones, estando este par o estos pares en resonancia por lo menos con otro par llevado por la molécula, llevándose a cabo esta adicion en una cantidad suficiente para dar origen a un producto de una reaccion de equilibrio entre el compuesto orgánico y por lo menos una de las dichas substancias por aislar, y suficiente para causar una precipitacion de este producto de reaccion de equilibrio, una filtracion del precipitado y un arrastre por vapor del compuesto orgánico del precipitado, con un producto de la substancia por aislar en forma purificada.
