载铁环烷酸-异辛醇-煤油体系异相水热反萃

Some factors effected on heterogeneous hydrothermal stripping from iron-loaded organic phase of naphthenic acid-isooctyl alcohol-kerosene,such as the concentrations of initial iron and naphthenic acid,the weight of"seed"of Fe2O3,temperature and time,were investigated.The process rate equation and the relation between stripping percent and time needed were established.The results showed the proces activation energy was 114 kJ·mol-1 and the heterogeneous hydrothermal stripping was controlled by the hydrolysis of naphthenic compound of iron.

载铁环烷酸水热反萃过程的研究

利用水热反萃的方法从载铁有机相中制备超细氧化铁粉末国内外文献还鲜见报道。分析了萃铁有机相的热稳定性以及有机相中铁浓度,自由环烷酸浓度,反应温度和晶种引入对水热反萃率的影响。由初速率方法求出反应活化能为94kJ/mol,表明水热反萃过程为化学反应控制。
