Abstract

a invenção se refere a um processo para separação de ácidos orgânicos de mistura de sais de amônio de um ou mais ácidos orgânicos e outros compostos por meio de um processo integrado. o processo envolve suspender a mistura de sais de amônio de um ou mais ácidos orgânicos e outros compostos em solvente (ou solventes) de hidrocarboneto seco ou misturas dos mesmos; em que o solvente (ou solventes) de hidrocarboneto selecionado ou misturas dos mesmos têm ponto de ebulição maior que 100 oc e formam um azeótropo com água. a mistura de reação obtida dessa forma é desidratada de modo azeotrópico seguido por esterificação de sal básico dos ácidos orgânicos por adição de álcool na presença de metal ou sal metálico; após isso, os ésteres individuais formados são separados por meio de destilação e hidrolisados para obter ácidos orgânicos correspondentes que têm mais de 98% pureza.
