Abstract
"PROCESSO PARA PRODUZIR áCIDO LáCTICO E SEUS PRODUTOS". A invenção provê um processo para produzir ácido láctico e produtos deste a partir de um meio contendo um sal de metal alcalino terroso de ácido láctico, compreendendo (a) reagir uma base conjugada de um metal alcalino de uma etapa subsequente com o meio para formar um sal de lactato de metal alcalino solúvel em água e um composto básico do metal alcalino terroso; (b) separar o sal de lactato de metal alcalino solúvel em água e o composto básico do metal alcalino terroso; (c) dividir o lactado de metal alcalino solúvel em água para formar uma base de metal alcalino conjugada e um produto de ácido láctico, produto este que é selecionado do grupo consistindo de ácido láctico, um derivado deste e combinações dos mesmos; (d) separar a base de metal alcalino conjugada e o produto de ácido láctico; (e) reusar a base de metal alcalino conjugada separada ou um produto desta na etapa (a); e (f) reusar o composto básico do metal alcalino terroso, separado na etapa (b), ou um produto deste para formar um sal de metal alcalino terroso de ácido láctico.
