Characterized and quantitative determination of mono- and bis(2-ethylhexyl)phosphoric acid

Mono- and bis (2-ethylhexyl) phosphoric acid have widely uses in industrially. Most oftheir commercial products are as mixture and they usually use for general application, likehydrometallurgy. There are different methods for their synthesis that most of them mono(2-ethylhexyl) phosphoric acid is often a side product in bis (2-ethylhexyl) phosphoricacid. With considering to different chemical properties of them, different procedures areexisting. In this research, these compounds are measured by indirect potentiometrictitration and plotting the differential titration curve for their quantitative determination then they are characterized by spectroscopy methods.
