Abstract

"PROCESSO PARA PRODUZIR UM áCIDO ORG NICO, áCIDO LáCTICO E UM éSTER DO MESMO". é descrito um processo para produzir um ácido orgânico e, opcionalmente, para simultaneamente produzir um éster do ácido orgânico. o processo compreende as etapas de (a) combinar um diluente aquoso, um sal de amónio de um ácido orgânico, e um álcool, formando assim uma mistura de alimentação líquida homogênea; (b) aquecer rapidamente a mistura de alimentação a uma pressao suficiente para suprimir pelo menos parte de vaporização do álcool e mantendo-a a urna temperatura e por um tempo suficiente para decompor o sal de amónio do ácido orgânico em amónia e ácido orgânico livre, enquanto se remove rapidamente a amónia do equipamento de transferência de reação-massa, e opcionalmente reagir pelo menos parte do ácido orgânico com o álcool para formar um éster do ácido orgânico, produzindo assim (i) uma corrente de produto vaporoso que compreende amónia, água e álcool e (ii) uma corrente de produto líquido que compreende ácido orgânico livre, opcionalmente éster e álcool, onde a quantidade total de álcool na corrente de produto vaporoso e na corrente de produto liquido, de cerca de pelo menos 10% em peso, está presente na corrente de produto líquido; e (c) recuperar o ácido orgânico livre e opcionalmente o éster da corrente de produto líquido. A mistura de alimentação líquida pode compreender um caldo bruto ou parcialmente purificado produzido por um processo de fermentação.
