Abstract
"PROCESSO METATéTICO DE áCIDO-SAL MEDIADO POR MEMBRANA TROCADORA DE CáTIONS". Um processo metatético [dupla troca] de ácido-sal mediado por membrana trocadora de cátions. Uma solução aquosa de sal está contida dentro de um primeiro compartimento sobre um lado da membrana junta com um agente de extração à base de amina, orgânico, de miscibilidade limitada em água, e uma solução aquosa de ácido está contida dentro de um segundo compartimento sobre o outro lado da membrana. ácido-produto é formado dentro do primeiro compartimento e é coletado no agente de extração à base de amina, orgânico, a partir do qual ele é recuperado. O processo é particularmente adequado para a recuperação de um ácido carboxílico a partir de seu sal.
