Abstract
LA INVENCION TRATA DE UN PROCEDIMIENTO PARA LA OBTENCION DE BISFENOL A, CON UNA PUREZA DE AL MENOS 99,95 % EN PESO DE P,PBISFENOL A (BPA). EL BPA PURIFICADO SEGUN LA INVENCION ES TERMOESTABLE Y TAMBIEN DE COLOR ESTABLE LO QUE OCASIONA UNA TERMOESTABILIDAD MEJORADA Y UNA MEJOR TRANSPARENCIA OPTICA EN LOS POLIMEROS SINTETIZADOS A PARTIR DE EL COMO P. E. POLICARBONATO. EL PROCEDIMIENTO SE CARACTERIZA POR UNA DESTILACION EN CUATRO ETAPAS.
