Iron(III) acetylacetonate, cas is 14024-18-1, it is a common heterocyclic compound, the iron-catalyst compound, its synthesis route is as follows.,14024-18-1

Nanosized Fe2O3 was synthesized by the thermolysisof an iron-containing precursor in a dispersion medium. Iron acetylacetonate prepared as describedin [7] was used as a precursor; the dispersion medium was diphenyl ether (DPE). The choice of DPE wasbased on the thermal stability, high boiling point (259C), and low toxicity of this material. Iron acetylacetonate(0.5 g) was dissolved in 10 mL of DPE;40 mL of DPE in a two-necked round-bottom flaske quipped with a reflux condenser was heated in an oil bath to 200C under vigorous stirring with a magnetic stirrer. After that, using a syringe, the iron acetylacetonate solution was rapidly introduced into hot DPE. The resulting mixture was held under vigorous stirring for 2 h to provide the completion of thermolysis and the formation of iron oxide particles; after that, the mixture was cooled and analyzed. To study the features of reduction of Fe2O3 and the chemisorption processes involving it, DPE was removed by vacuum distillation; the resulting material was a black powder.

With the rapid development of chemical substances, we look forward to future research findings about Iron(III) acetylacetonate

Iron Catalysis in Organic Synthesis: A Critical Assessment of What It Takes To Make This Base Metal a Multitasking Champion

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14024-18-1,Iron(III) acetylacetonate,as a common compound, the synthetic route is as follows.

Nanoparticles narrow diameter distribution were prepared by the high-temperature decompositionof Co(acac)2 and Fe(acac)3 with the 1:2 Mratio (0.6:1.2mmol) together with 1-2 octanediol, diphenyl ether (boiling point at 550 K)and oleic acid and oley-lamina as surfactants. The particle size was tailored by the sur-factant: precursor molar ratio ([Surf.]:[Prec.])according to there-ference [15]. The preparation was magnetically stirred and heated up to the boiling temperature T535 K for 120 min. After synthesis the nanoparticles were extracted by adding ethanol followed by centrifugation(14,000rpm/30min). After that,they were washed with acetone and centrifuged once again. The final sample consists in a black powder constituted by cobalt ferrite nanoparticles covered with an oleic acid layer, which is strongly linked to the surface, improving the chemical stability, and avoiding agglomeration. The samples were labeled S2,S5,and S7 with mean diameter 2.0,4.5,and 7.0 nm respectively, obtained from the TEM analysis., 14024-18-1

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14024-18-1,Iron(III) acetylacetonate,as a common compound, the synthetic route is as follows.

Fe(acac)3 (3 mmol) was dissolved in 20 ml of oleylamine and 5 ml of n-hexane. The reaction mixture was thoroughly stirred under N2 atmosphere for 30 min in a 50 ml Teflon-lined stainless steel autoclave that was carefully sealed. The autoclave was heated in a furnace at 190 C for 8 h under autogenous pressure. The resulting dark suspensions were extracted by adding 50 ml of ethanol followed by centrifugation. After washing the precipitates three times with ethanol, uniform Fe3O4 NPs were formed. These NPs were redispersed into n-hexane and a black-brown n-hexane dispersion of Fe3O4 NPs was thus obtained. Thus, the Fe3O4 suspension was transferred to 100 ml volumetric flask, evenly mixed with n-hexane for measurement of concentration of Fe3O4 through the 1,10-phenanthroline monohydrate dyeing method using UV-Vis spectrophotometer. Similar procedures for the preparation of Fe3O4 NPs were carried out at different conditions, including different reaction temperatures, times, and solvents. The solvothermal temperatures for samples S1 and S3 differed from that for S2. For samples S4-S6, the reaction times differed from that of S2. For samples S7-S9, the content of n-hexane differed from that of sample S2. The detailed preparation conditions are listed in Table 1 .

The magnetic nanoparticles were synthesized according to a previously reported procedure26. Briefly, a solution of Fe(acac)3 (5.65 g, 0.016 mol), benzyl ether (80 mL) and oleylamine (80 mL) was heated to 110 C and allowed to reflux for 1 h with vigorous stirring. The temperature was raised to 210 C and then refluxed for 2 h under an argon atmosphere. After cooling to room temperature, the reaction mixture was centrifuged at 10,000 rpm for 20 min, affording the magnetic nanoparticles (Fe3O4) as a black solid. The magnetic nanoparticles were then dispersed in a mixture of 1-propanol (180 mL), conc. NH4OH (25 mL) and deionized water (18 mL) in a 500 mL round-bottom flask by ultra-sonication for 30 min under an argon atmosphere. Following this, tetraethylorthosilicate (TEOS) (6 mL, 0.027 mol) was added dropwise for 30 min with vigorous stirring. After stirring at room temperature for 6 h, thesilica-coated magnetic nanoparticles (Fe3O4(at)SiO2) were separated from the solution using an external magnet and then washed twice successively with 1-propanol and deionized water, respectively. The Fe3O4(at)SiO2 nanoparticles (brown solid) were then dried under vacuum at 60 C for 6 h, prior to use., 14024-18-1

Cobalt (II) acetylacetonate Co(acac)2 and Iron (III) acetylacetonateFe(acac)3 precursors weighted as 1:2M ratio was dissolved in 50 ml of de-ionized water. The aqua solution was kept warm at 40 C for few minutes and very few drops of inorganic chemical reagent was added dropwise and stirred for 30 min to mix the cations homogeneously throughout the solution. 1% of alkali solution was added dropwise to the aqua precursor solution for a better control of particle size, which acts as a precipitating agent as well as maintaining the pressure in the autoclave by lowering the equilibrium vapour tension of water. Finally,the precursors solution was continuously stirred for 30 min and transferred into 150 ml Teflon coated stainless steel autoclave. Then the autoclave was sealed and kept in the muffle furnace for heat treatmentat the optimised reaction temperature of 200 C for 6 h and allowed to cool down to room temperature. The obtained dark precipitation was filtered by Whatman filter paper and washed several times by de-ionized water and absolute ethanol. The precipitate was then dried at 80 C for 5 h in hot air oven and subsequently annealed at 700 and 800 C. The samples were named as S1 (as-prepared),S2 (annealed at 700 C), and S3 (annealed at 800 C).

Iron(III) acetylacetonate, cas is 14024-18-1, it is a common heterocyclic compound, the iron-catalyst compound, its synthesis route is as follows.,14024-18-1

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.)
