| 利用水/OP-正已醇/环已烷微乳液作为反相胶束微反应器,通过调节微反应器中的溶水量,制备微米级的Fe3O4,并考察水/OP-正已醇/环已烷微乳液的性能。结果得到,微乳液法制备Fe3O4的最佳工艺条件为:表面活性剂OP与助表面活性剂环已醇之比为3:2,水相为Fe2+:Fe3+=2:1的水溶液,乳化温度为30℃。该微乳液法制备Fe3O4的工艺设备简单,制得的粒子粒径较小,且可以通过调节溶水量来改变微液滴反应场的大小,进而控制产物微粒的大小,是制备性能良好Fe3O4微粒较好的体系。 |

| Abstract: |
| Fe3O4 minute particles were prepared by utilizing H2O/OP-Hexanol/Cyclohexane microemulsions and through regulating amount of water dissolved in reverse micell microreactor,and investigated performance of H2O/OP-Hexanol/Cyclohexane microemulsions The result was got,the best process conditions of preparing Fe3O4 minute particles by microemulsions were:the proportion of surface-active agent OP and helping the surface-active agent Hexanol was 3:2,containing Fe2+ and Fe3+ aqueous solution regarded as aqueous phase, proportion of them for 2:1,emulsification temperature was 30℃.The craft equipment of preparing Fe3O4 minute particles by microemulsions is simple,reverse micell microreactor can be changed through regulating the amount of water dissolved,and then can control the size of the particle,this is a better system of performance of preparing good Fe3O4 particle. |
