Abstract

Procedimiento para la obtención de aminas, a partir de formamidas, caracterizado porque una formamida de fórmula R1 - NH - CHO donde R1 significa alquilo, cicloalquilo o aralquilo, se hace reaccionar con una amina de fórmula R2R3NH donde R2 y R3 significan hidrógeno, alquilo, cicloalquilo, aralquilo o arilo, o donde los restos R2 y R3, junto con el átomo de nitrógeno y en su caso dado ulteriores heteroátomos forman un anillo heterocílico de 5 hasta 8 miembros, donde solo uno de los restos R2 y R3 puede ser hidrógeno y donde como mínimo uno de los restos R2 y R3 es distinto a R1, a temperatura mas elevada y la parte de los productos de reacción de punto de ebullición más bajo se retira destilativamente de la mezcla de reacción.
