Dioleyl phosphoric acid

Sodium bis(2-ethyl-l-hexyl) sulfosuccinate (Aerosol OT, AOT) sodium do-decylbenzene sulfonate (SDBS) sodium di-2-ethyl hexyl phosphate (NaDEHP) dioleyl phosphoric acid (DOLPA) di(tridecyl) phosphoric acid (DTDPA) sodium dodecyl sulfate (SDS) 1,3-dilauroyl glycerol-2-disodium phosphate (2-modified 1,3-diacyl glycerol)... 

Aqueous pH alters the protein charge property and affects the extraction efficiency. Haemoglobin (Mw 64,500, pi 6.8) is a difficult protein in terms of being able to completely extract it into reverse micelles. The representative anionic surfactant, di-2-ethylhexyl sulfosuccinate (AOT), cannot extract it, and gives rise to an interfacial precipitate. In contrast, we succeeded in the complete extraction of haemoglobin using synthetic anionic surfactants, dioleyl phosphoric acid (DOLPA), as seen in... 

A number of variations of the basic synthesis methods have been reported. In the works of Morooka and coworkers [104,105], the microemulsion was prepared by a solvent extraction process in which a bulk organic phase containing the surfactant dioleyl phosphoric acid (DOLPA) in isooctane was contacted with a bulk aqueous phase containing KCl and NH3 (for pH adjustment). The extraction process can be expressed as...
