Abstract

PROCEDIMIENTO DE PREPARACION DE PARTICULAS SOLIDAS DE UN DIHIDROXIFENIL-METANO, TAMBIEN DENOMINADO BISFENOL-F, DE CALIDAD TECNICA. SE FORMA UNA DISPERSION DE GOTITAS DE BISFEROL-F EN UN MEDIO LIQUIDO, QUIMICAMENTE INERTE, A UNA TEMPERATURA IGUAL O SUPERIOR A 70GC. A CONTINUACION SE ENFRIA EL CONJUNTO, MANTENIENDO, AL MISMO TIEMPO, DICHO ESTADO DE DISPERSION, CON LO QUE PRECIPITA EL BISFENOL-F EN FORMA DE PARTICULAS SOLIDAS. LA TEMPERATURA DE ENFRIAMIENTO DEBE SER INFERIOR A 35GC. EL MEDIO LIQUIDO EMPLEADO ES, PREFERENTEMENTE, AGUA Y SU PROPORCION EN PESO CON RESPECTO AL BISFENOL ES SUPERIOR A 1,6:1. ESTE COMPUESTO ES DE EMPLEO EN LA FABRICACION DE RESINAS FENOLICAS Y DE RESINAS DE POLICARBONATOS.
