Abstract

Un proceso para la rectificacion de ácidos carboxílicos no saturados a partir de solventes en los cuales los ácidos fueron absorbidos después de la reaccion de síntesis, la reaccion se interrumpe brevemente y se lava la columna de rectificacion con una solucion básica. La interrupcion se realiza a intervalos regulares de tiempo. La solucion básica empleada es una solucion acuosa de hidroxido de metal alcalino y/o metal de tierra alcalina, de preferencia NaOH, KOH, Ca(OH)2 o susoxidos anhidros; se pueden emplear también solventes orgánicos polares alcalinos como aminas o amidas.
