Abstract

Procedimiento mejorado para la preparación de N,N,N¿,N¿-etraacetiletilendiamina mediante acetilación de N,N¿-diacetiletilendiamina con anhídrido de ácido acético a una temperatura de 120 a 170ºC, caracterizado por a) se utiliza N,N¿-diacetiletilendiamina y anhídric de ácido acético en la proporción de peso de 1:1 hasta 1:10; b) la acetilación se interrumpe antes de establecer el equilibrio de reacción entre N,N¿-diacetiletilendiamina y N,N,N¿,N¿-tetraacetiletilendiamina; c)la mezcla de reacción coloreada de pardo, obtenida, se somete después a antes de la separación de N,N,N¿,N¿-tetraacetiletilendiamina mediante cristalización, a una purificación para eliminar las impurezas coloreadas y D) los componentes de reacción, purificados y recuperados, no reaccionados totalmente para formar N,N,N¿,N¿-tetraacetiletilendiamina, son aportados nuevamente a la acetilación.
