Abstract

"PROCESSOS PARA PRODUZIR éSTERES DE CITRATO" A presente invenção refere-se a processos para produzir ésteres de citrato em um modo económico. São preparados ésteres pela esterificação de um caldo de fermentação contendo ácido cítrico tendo sido tratado para remover cátions e, opcionalmente, outras impurezas, mas contendo açúcar (es). São também preparados ésters pela relação de um fonte aquosa de ácido cítrico impura com um álcool para proporcionar uma mistura reagida aquosa/orgânica, heterogênea, em que a fase orgânica contém o éster e a fase aquosa retém impurezas solúveis em água. Uma separação de fase líquida é então usada para separar as fases orgânicas e aquosas, separando, convenientemente, as impurezas do produto e evitando a energia-destilação intensiva de água do meio de reação.
