摘要: 第四周期过渡金属硫酸盐及其水合物作为反应的催化剂已有许多报导。对同一反应,有人探索了催化剂的活性与金属的物理参数(离子半径、电荷、第二电离势……)之间的关系,并建立了一些经验关系式。

Abstract: Based on the activity of catalysts for hydrated sulfate in mutarotation of α-D-glucose, it was found that the relations between lgkα,△E, △Sof mutarotation of α-D-glucose and parameters of metal ion are as follows lgkα△E, △S=a(0.05x+0.01y)+b where x=Z1.8/r,y=I(1+aD) Z is pesitive charge of metal ion, r is radius of metal ion in catalysts, Iis tovalent parameter,α is polarizability of metal ion, Dis parameter which depends on the electron configuration of metal ion and the d electron number.
