Iron(III) acetylacetonate, cas is 14024-18-1,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.

A typical procedure for preparation of oil-soluble magnetite nanoparticles is briefly described as follows: first, 20 mL of diethylene glycol, 0.70 g (2 mmol) of iron (III) acetylacetonate, and 1.06 mL (3 mmol) of oleic acid were mixed in a 50 mL Teflon-lined stainless autoclave while magnetically stirring. Then, the autoclave was put into oven, kept at 180C for 5 h. After cooled to room temperature naturally, 40 mL ethanol was added to yield a black precipitate. The black Fe3O4 precipitate was separated by centrifuging at 10,000 rpm for 20 min, and re-dispersed in 10 mL of hexane or dried at 60C under vacuum for 24 h. (The as-prepared product was donated as SO1.) The as-synthesized Fe3O4 colloid in hexane is hydrophobic and stable for nearly a year, while the dried Fe3O4 sample can be stable for several months. The synthesis of water-soluble magnetite nanoparticles was carried out only by reacting an iron precursor, iron (III) acetylacetonate (Fe(acac)3), in the polyol medium (diethylene glycol) without oleic acid under the same reaction conditions. After cooling down to room temperature, 40 mL of ethyl acetate was added to the reaction solution resulted in a black precipitation of magnetite nanoparticles which was then separated from the solution by centrifuging at 10,000 rpm for 20 min. After washed with ethyl acetate for three times, the precipitation was re-dispersed in polar solvents such as ethanol and water for further investigation. The Fe3O4 solid productions could also be obtained by drying the precipitation at 60C under vacuum for 24 h. (The as-prepared product was donated as SW1.)
