A new anionic surfactant that has never been reported before, sodium di-[ (2-ethylhexyloxy) ethyl] phosphate (DEEPA), has been synthesized. Its structure has been characterized with H-1 NMR and FT-IR spectrum. Hydrolysis of olive oil catalyzed by lipase using reversed micelle composed of DEEPA and isooctane was carried out. The results show that the catalytic performance of DEEPA reversed micelle is superior to that of AOT reversed micelle, and more superior to that of oil-water double phased system.
