Abstract

ESTA INVENCION SE REFIERE A UNA SOLUCION PARA DETECTAR LA FALSIFICACION DE BILLETES. LA SOLUCION CONTIENE YODO EN UNA CONCENTRACION DE 0,005 A 3 GRAMOS/LITRO Y LOS SOLVENTES DE LA SOLUCION PUEDEN SER: ALCOHOLES, CETONAS, POLIALCOHOLES, ESTERES, ETERES, UNA MEZCLA DE SOLVENTES QUE PERTENEZCAN A LA MISMA CLASE QUIMICA O A VARIAS CLASES DE LOS SOLVENTES ANTEDICHOS. EL SOLVENTE O MEZCLA DE SOLVENTES, SI SON MISCIBLES EN AGUA, CONTIENE AGUA DESTILADA EN UNA RELACION DE 99:1 A 1:99 EN VOLUMEN; EN LOS OTROS CASOS EL SOLVENTE ORGANICO O LA MEZCLA DE SOLVENTES SE SATURA CON AGUA DESTILADA A UNA TEMPERATURA DE 20 (GRADOS) C. LA SOLUCION QUIMICA PREPARADA, QUE SE COLOCA DENTRO DE BOLIGRAFOS, O PLUMAS ESTILOGRAFICAS, O ROTULADORES U OTROS POSIBLES DISTRIBUIDORES, SE UTILIZA PARA RATIFICAR EL BILLETE. EN EL CASO DE UNA FALSIFICACION, LA LINEA QUE HAY EN EL BILLETE CAMBIA, EN UN MINUTO APROXIMADAMENTE, A UNO DE LOS SIGUIENTES COLORES: LILA, LILA VIOLETA, AZUL MARINO VIOLETA, AMARILLO HABANO. EN EL CASO DE UN BILLETE GENUINO, LA LINEA PINTADA CON LA SOLUCION NO CAMBIA DE COLOR Y DESAPARECE COMPLETAMENTE DEL BILLETE RATIFICADO.
