Abstract
SE PRESENTA UN PROCEDIMIENTO PARA BLANQUEAR PULPA QUE COMPRENDE LOS PASOS DE BLANQUEAR LA PULPA CON PEROXIDO DE HIDROGENO Y UNA CANTIDAD EFECTIVA DE AL MENOS UN AGENTE QUELANTE DE 1AMINOALCANO-1,1-DIFOSFONATO BIODEGRADABLE PARA MEJORAR EL BLANQUEADO DE LA PULPA. TAMBIEN SE PRESENTA EL USO DE 1AMINOALCANO-1,1-DIFOSFONATO PARA MEJORAR EL BLANQUEADO DE LA PULPA CON PEROXIDO DE HIDROGENO, ASI COMO EL PRETRATAMIENTO DE LA PULPA CON 1-AMINOALCANO-1,1-DIFOSFONATO ANTES DE PASO DE BLANQUEADO CON PEROXIDO DE HIDROGENO. FINALMENTE, TAMBIEN SE PRESENTA EL DESTINTADO DE PULPA EN LA PRESENCIA DE 1-AMINOALCANO1,1-DIFOSFONATO.
