| 各位虫友有人做过油酸铁吗？我按照nature materials 2004，3，891的方法，它合成出来只用水洗，然后干燥，我用旋转蒸发也很难将其干燥成文献所说的waxy solid form，因此在后面得iron oxide合成中前驱物很难称量，而且在加热中很很多泡沫搞得回流时经常爆沸，有虫友有经验吗？ |

The mixed-metal(Co2+Fe23+)-oleate complex was prepared by reaction of sodium oleate and a mixture of Fe3+ and Co2+ chlorides. Ina typical synthesis, 4 mmol of FeCl3, 2 mmol of CoCl2, 16 mmol of sodium oleate (C18H33O2Na), 10 mL of H2O, 10 mL of ethanol, and 20 mL of hexane were mixed and refluxed at 60 C for 4 h. The mixed Co2+Fe2 3+-oleate complex (CoFe2- (C18H33O2)8) was obtained by separation of the water phase and subsequent evaporation of the residual ethanol and hexane at 70 C and water at 110 C. |
