Abstract
SE PRODUCE UN ADUCTOR CRISTALINO DE BISFENOL A Y FENOL DE ALTA PUREZA MEDIANTE LA CRISTALIZACION DE MULTIPLES FASES DE UNA PASTA AGUADA FENOLICA DE BISFENOL A CON UNA SEPARACION DE CRISTAL INTERPUESTA ENTRE CADA FASE. LA PUREZA DEL DISOLVENTE DE FENOL QUE SE UTILIZA PARA PREPARAR LAS SOLUCIONES PARA LAS FASES DE CRISTALIZACION SE CONTROLA PARA QUE AUMENTE PROGRESIVAMENTE. EL ADUCTOR CRISTALINO OBTENIDO EN LA FASE DE CRISTALIZACION FINAL SE LAVA CON FENOL PURIFICADO.
