Abstract

Patente de Invenção: <B>"PROCESSO PARA PREPARAR áCIDO IMINODIACéTICO DE N-FOSFONOMETIL"<D>. A presente invenção refere-se a um processo de poupar energia e efluente para a produção de ácido iminodiacético de N-fosfonometil (PMIDA), um intermediário na preparação de glifosato. Um sal de metal de álcali de ácido iminodiacético é reagido com ácido fosforoso e um ácido mineral forte, ou uma fonte do mesmo para formar fosfito iminodiacético e o sal de metal de álcali do ácido mineral forte. Após remoção do último sal, o fosfito iminodiacético é convertido em ácido iminodiacético de N- fosfonometil PMIDA para reação com formaldeído. O PMIDA é recuperado e a solução remanescente pode ser reciclada no processo.
