Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA LA SEPARACION RECTIFICATIVA DE ACIDO (MET)ACRILICO DE UNA MEZCLA QUE LO CONTIENE. SE REALIZA RETIRANDO EL ACIDO (MET)ACRILICO DE LA COLUMNA DE RECTIFICACION POR ENCIMA DEL LUGAR POR DONDE ENTRA LA MEZCLA LIQUIDA QUE LLEVA EL ACIDO (MET)ACRILICO EN LA COLUMNA DE RECTIFICACION, Y AL MENOS EN UN LUGAR POR DONDE SALE EL LIQUIDO DE RETORNO SE SEPARAN DE EL LOS ACIDOS (MET)ACRILICOS OLIGO- Y/O POLIMERIZADOS QUE LLEVA. FINALMENTE EL LIQUIDO DE RETORNO SE VUELVE A PONER EN LA COLUMNA DE RECTIFICACION.
