Abstract: Procedimiento para la purificación de difosfitos orgánicos de la fórmula general (I)**Fórmula** en la que R1, R2, R3 y R4 representan independientemente uno de otro hidrógeno, alquilo C1-C6 no sustituido de cadena recta o ramificado, alcoxi C1-C6 no sustituido de cadena recta o ramificado, arilo C6-C10, cloro, formilo, acilo o (alcoxi C1- C6)carbonilo, en la que dos radicales R1 a R4 adyacentes conjuntamente con los átomos de carbono del núcleo de benceno a los cuales están unidos, pueden representar también un sistema de anillo condensado con otro anillo de benceno, R5, R6, R7, R8, R9, R10, R11 y R12 representan independientemente uno de otro hidrógeno, alquilo C1-C6 no sustituido de cadena recta o ramificado, alcoxi C1-C6 no sustituido de cadena recta o ramificado, arilo C6-C10, cloro, formilo, acilo o (alcoxi C1-C6)carbonilo, en la que dos radicales R5 a R12 adyacentes conjuntamente con los átomos de carbono del núcleo de benceno al cual están unidos, pueden representar también un sistema de anillo condensado con otro anillo de benceno, en el cual un difosfito orgánico crudo de la fórmula general (I), que está disuelto por lo menos parcialmente en un primer solvente (L1) que es elegido de entre (alquil C1-C4)bencenos, precipita por adición de un segundo solvente (L2), que es elegido de entre metanol, etanol, etilenglicoldimetiléter y mezclas de ellos.
