Abstract

Un procedimiento para la purificación de trihidrocarbilfosfina con al menos un grupo arilo y al menos un grupo alquilo o cicloalquilo en la molécula, a partir de una masa de reacción que comprende la trihidrocarbilfosfina, comprendiendo el procedimiento cristalizar la masa de reacción utilizando un disolvente constituido esencialmente por metanol. El procedimiento proporciona una producción inesperadamente eficaz de compuestos de trihidrocarbilfosfina con purezas de al menos el 97% en moles, y más preferiblemente de al menos aproximadamente el 99% en moles. Es otra realización de la invención una neomentildifenilfosfina con una pureza de al menos el 97% en moles producida mediante cristalización de neomentildifenilfosfina con una pureza inferior al 97% en moles, utilizando un disolvente constituido esencialmente por metanol.
