Abstract

Se describe un procedimiento para producir un producto de ácido carboxílico purificado. El procedimiento comprende remover las impurezas de una suspensión de ácido carboxílico crudo en una zona de desplazamiento de sólido-líquido para formar un producto en forma de suspensión. El producto de suspensión es tratado adicionalmente en una zona de oxidación por etapas y en una zona de cristalización, para formar un producto cristalizado. El producto cristalizado es adicionalmente enfriado en una zona de enfriamiento y es subsiguientemente filtrado y secado en una zona de filtración y secado. El procedimiento produce un producto de ácido carboxílico purificado que tiene buen color y bajos niveles de impurezas sin usar etapas de purificación tales como hidrogenación.
