Abstract
"PROCEDIMENTO PARA PURIFICAR SOLUçõES DE GLISOFATO MEDIANTE NANOFILTRAçãO". Sendo que a presente invenção descreve um procedimento para purificar soluções de Glifosato (N-fosfonometilglicina) provenientes da síntese do Glifosato, mediante a oxidação do ácido N-fosfonometilimidodiacético, e que contêm formaldeído e ácido fórmico como impurezas principais, caracterizado pelo fato de fornecer uma solução inicial de Glifosato com uma concentração de Glifosato compreendida entre 0,1 e 3% p/v, uma concentração de formaldeído compreendida entre 0,5 e 1% p/v e uma concentração de ácido fórmico compreendida entre 0,1 e 0,6% p/v; ajustar o pH da referida solução inicial de Glifosato a um valor compreendido entre 2,5 e 3,5, mediante uma base selecionada entre uma alquilamina, hidróxido de amónio, hidróxido de sódio ou de potássio; submeter a referida solução a uma operação de nanofiltração, a uma temperatura compreendida entre 10 e 35<198>C e a uma pressão compreendida entre 25 e 35 Kg/ cm^ 2^ ;levando-se adiante a referida operação de nanofiltração, através de, pelo menos, uma membrana de nanofiltração; recuperar a solução concentrada de Glifosato, que contém mais de 97% do Glifosato da solução inicial, e cuja concentração de Glifosato é de aproximadamente 8%; e descartar a solução permeada que contém entre 50 e 95% do formaldeido e do ácido fórmico presentes na referida solução inicial.
