反丁烯二酸存在下低浓度Cr^(3+)水解聚合作用的热力学性质研究

STUDIES ON THE THERMODYNAMICAL PROPERTIES THE HYDROLYTIC POLYMERIZATION FOR THE CHROMIUM ION IN THE PRESENCE OF FUMARIC ACID

用微量量热仪测定了在反丁烯二酸存在下低浓度Ｃｒ３＋离子的水解聚合作用的反应热，结合戴安邦等人的研究工作，得到了不同温度下。

The hydrolytic polymerization of chromium(Ⅲ) ion of low concentration was studied by microcalorimetric method. The power_time curve was determined using the 2277 thermal activity monitor, from this curve we identified the reaction heat at 333K and calculated the hydrolysis constants (K°) and thermodynamical functions (Δ rG θ m, Δ rS θ m ) of chromium(Ⅲ) ion at different temperature.
