FeⅢ(Fe(Ⅲ)各种形式平均克磁化率)比水体系及未经放置的加醇体系有所增加,pH滴定曲线终点前移,紫外、可见光度揭示有新物种生成,我们认为体系中可能生成了含醇的多元配合物,机理有待进一步探讨。 |

| Abstract: By means of potentiometric, spectrophotometric and magnetochemical methods, effects of addition alcohol to aqueous solution of ferric citrate on the hydrolytic polymerization have been investigated. The experimental results show that introduce alcohol into a solution of ferric citrate and let it stand for several hours, the value of X
Fe3+ (gram susceptibility of total iron in solution) is relatively larger than the same solution without standing or a solution of pure ferric citrate. End point of pH ti-tration curve is changed also. Visible and ultraviolet spectra show the formation of new species containing alcohol. We believe that alcohol molecules substitute some water molecules as ligands of Fe3+ and polyatomic coordination compounds with alcohol are produced probably. |
