Abstract

Las modalidades refieren a un proceso continuo para la producción de hidroxietilpiperazina que incluye alimentar un reactor con piperazina pura, piperazina reciclada y óxido de etileno para formar hidroxietilpiperazina en bruto, en donde el reactor es un reactor de tanque agitado continuo o un reactor de flujo pistón. El proceso incluye además alimentar de forma continua la hidroxietilpiperazina en bruto desde el reactor a un sistema de destilación que incluye al menos una columna de destilación, el sistema de destilación produce al menos una corriente de piperazina reciclada y una corriente de hidroxietilpiperazina, la corriente de piperazina reciclada incluye la piperazina reciclada con la que se alimenta el reactor para formar la hidroxietilpiperazina en bruto, y la corriente de hidroxietilpiperazina incluye al menos 60 % en peso de hidroxietilpiperazina en función del peso total de la corriente de hidroxietilpiperazina.
