Title: Method for the purification of bis (2-ethyl-hexyl)phosphoric acid

Abstract

Foreign products including the neutral organophosphorous compounds and the iron salts normally present in commercial bis(2ethyl-hexyl) phosphoric acid(HDEHP), and the radiolytic degradation products of HDEHP on exposure of HDEHP to beta and gamma irradiation are removed from HDEHP containing one or more of such products by contacting the said foreign product containing HDEHP with a macroreticular anion exchange resin in base form whereby the DEHP- ion of HDEHP exchanges with the anion of the resin and is thus adsorbed on the resin and the said foreign products are not adsorbed and will pass through a bed of particles of the resin. The adsorbed DEHP- ion is then eluted from the resin and acidified to form and recover the purified HDEHP. (auth)
