Abstract

PROCEDIMIENTO PERFECCIONADO DE PRODUCCION DE SALICILATO SODICO Y ACIDO SALICILICO. SE HACE REACCIONAR FENOLATO SODICO CON DIOXIDO DE CARBONO EN UNA SOLA ETAPA A TEMPERATURA SUPERIOR A 165 C. LA ZONA DE REACCION ESTA CONSTITUIDA POR UN MEZCLADOR Y AMASADOR QUE COMPRENDE HOJAS CONTRARRESTADORAS QUE ASEGURAN UN MINUCIOSO MEZCLADO DEL FENOL, EL HIDROXIDO SODICO, EL FENOLATO SODICO Y EL DIOXIDO DE CARBONO REACTIVOS. CON ESTE PROCEDIMIENTO SE REDUCEN LA FORMACION DE SALES SODICAS SUB-PRODUCTOS DE ACIDOS NO SALICILICOS.
