Abstract
"PROCESSOS PARA PRODUZIR UMA SUSPENSãO DE áCIDO CARBOXìLICO PURIFICADO, PARA PURIFICAR UM PRODUTO DE OXIDAçãO EM ESTáGIOS, PARA PRODUZIR UM PRODUTO DE áCIDO CARBOXìLICO PURIFICADO, E, SUSPENSãO DE áCIDO CARBOXìLICO PURIFICADO". é apresentado um processo para produzir uma suspensão de ácido carboxílico purificado. O processo compreende a remoção de impurezas de um produto cristalizado, em uma zona sólida de deslocamento sólido líquido, para formar a suspensão de ácido carboxílico purificado. O processo produz uma suspensão de ácido carboxílico purificado, tendo uma cor boa e baixos níveis de impurezas, sem o uso de etapas de purificação, como hidrogenação ou um processo de remoção de impurezas.
