Abstract

Procedimiento de reordenación en continuo de una sal alcalina de un ácido carboxílico aromáticosometidas a una presión de anhídrido carbónicoen presencia de un disolvente orgánico líquido y que sea inerte en las condiciones de la reacción de reordenaciónintroduciéndose en continuo la sal alcalina del ácido carboxílico aromático en forma de suspensión dentro del disolventemediante un circuito constituido por un dispositivo de alimentación y otro de precalentamientocaracterizado porque se introduce en continuo anhídrido carbónico en el reactor por medio del circuito de alimentación de la suspensión de la sal alcalina correspondiente el ácido carboxílicointroduciéndose en el circuito a través de cualquier lugar donde la temperatura sea inferior a la temperatura de reordenación inicial de la sal alcalina del ácido carboxílico aromático.
