Abstract
"PROCESSOS PARA A PRODUçãO DE áCIDO ASCóRBICO, DE UM CO-PRODUTO BASE E DE UM CO-PRODUTO DE SAL DE METóXIDO". A presente invenção refere-se a processos eletroquímicos para a recuperação de ácido ascórbico partindo de um sal ascorbato sem a cogeração de uma corrente de sal rejeitado e mantendo-se alta condutividade da célula eletroquímica fornecendo desse modo conversão quantitativa dos sais a ascórbico tanto em um processo do modo em batelada como contínuo. Em uma modalidade a corrente de alimentação que compreende sal ascorbato está dissociada sob a influência de um campo elétrico e sujeita a eletrodiálise de desdobramento da áuga. O íon ascorbato se combina com um próton e o cátion de sal se combina com um íon hidroxila para formar ácido ascórbico e base, respectivamente. A corrente de alimentação compreende ainda um sal inorgânica que mantém alta condutividade na célula, facilita a conversão quantitativa de sais ascorbato a ácido ascórbico tanto em processos do modo em batelada como contínuo e promove a precipitação e a cristalização de ácido ascórbico como um pó fino. As células eletroquímicas úteis nos processos incluem arranjos com uma combinação de pelo menos uma membrana catiónica e pelo menos uma membrana bipolar em combinação com pelo menos uma membrana catiónica.
