Abstract

"PROCESSO PARA A PRODUçãO DE N-(FOSFONOMETIL) GLICINA". A invenção refere-se a um processo para a produção de N-(fosfonometil) glicina que envolve as etapas a seguir: (a) oxidação do ácido N-(fosfonometil) iminodiacético (PMIDA) com peróxidos ou com oxigênio em um meio aquoso na presença de um catalisador heterogêneo a uma temperatura na faixa de 50 até 150<198>C; (b) separação subseq³ente do catalisador sólido da suspensão aquosa da reação proveniente da etapa (a); (c) concentração da solução clara da reação proveniente da etapa (b), especialmente por evaporação e; (d) separação da N-(fosfonometil) glicina da solução concentrada da reação proveniente da etapa (c), especialmente por filtração. De acordo com a invenção, a solução aquosa da reação proveniente da etapa (d) (licor mãe) é retornada com pequenas quantidades de N-(fosfonometil) glicina e subprodutos para a etapa (b) (separação do catalisador) e/ou para a etapa (c) (concentração). Isto resulta em aumentar distintamente o rendimento com uma pureza constante do produto e em reduzir notavelmente a quantidade do licor mãe.
