Abstract

EL BISFENOL-A PRODUCIDO POR LA CONDENSACION DE LA ACETONA Y DEL BISFENOL ES LIBERADO DE PRODUCTOS CONTAMINANTES MEDIANTE SU FUSION EN AGUA Y SU CRISTALIZACION A PARTIR DE ELLA. EL LAVADO FINAL, EN AGUA CALIENTE, LIMPIA LAS SUPERFICIES DE CRISTAL DE LOS CONTAMINANTES RESTANTES SIN LA NECESIDAD DE SOLVENTES ORGANICOS.
