Abstract

Proceso para la producción simultánea y continua de dos diferentes mezclas de predominantemente 4,4´-MDI y 2,4´-MDI en un proceso de cristalización por fusión de suspensión de etapa única mediante el cual se utiliza una mezcla de corriente de alimentación de diisocianato mezclado [Mlx] para producir simultáneamente dos corrientes de diisocianato mezclado [MIy y MIz] en donde x = 80 a 92, y = 97 a 99 y z = 60 a 80 preferentemente x = 82 a 88, y = 97.2 a 98.5 y z = 63 a 70 en donde x, y y z son porcentajes en peso del isómero de 4,4´-MDI contenido en la mezcla de isómero de diisocianato -.
