N,N-N-octylaminedimethylenephosphonic acid (OADMPPA)

Thread Content

Some sources indicate that the extractant “N,N-n-octylamino-dimethylenephosphonic acid (OADMPPA)” can be used in the wet phosphoric acid industry to remove iron and aluminum ions. Question: Are there any forum members who have carried out wet-process phosphoric acid extraction? Are there any wet phosphoric acid plants that use this extraction process for iron removal? Does anyone know the manufacturer of this extractant? I would like some samples.
