Abstract

Patente de Invenção: "PROCESSO DE PRODUçãO DE áCIDOTARTáRICO A PARTIR DE UMA MATéRIA-PRIMA CONTENDOBITARTARATO DE POTáSSIO". A matéria-prima contendobitartarato de potássio (KHT) é misturada com solução aquosa dehidróxido de potássio em um primeiro estágio de reação, no qualKHT é virtualmente completamente reagido para obter tartaratodipotássico (DKT). A solução aquosa contendo DKT é misturadacom ácido adicionado em um estágio de precipitação, a um valorde pH de 2,0 a 5,0, e uma suspensão contendo KHT cristalizado éproduzida. O KHT cristalizado é separado da suspensão, lavadocom água, e produz-se uma solução saturada com KHT com pelomenos 80% em peso. Desta solução, remove-se potássio, eobtém-se uma solução aquosa produto de ácido tartárico, da qualágua é, pelo menos parcialmente, removida.
