摘要
本文用核磁共振法测定了高氯酸铊-18冠6-水体系的各个热力学参数.该体系的络合稳定常数、热焓、熵和吉氏函数在25.1℃时的数值分别为:lgK=2.11±0.02、△H=-4.49±0.17kcal/mol、△S=-5.35±0.54cal/mol和△G°=-2.88kcal/mol。所得结果与用量热法测得的数值一致。
The thermodynamics parameters for the reaction of 18-crown-6 with Tl(I)in water were determined by using NMR.The stability constant,enthalpy,entropy,and free energy were calculated to be 1gK=2.11±0.02,AH=-4.49±0.17 kcal/mol,△S=-5.35±0.54 cal/mol and△G0=-2.88 kcal/mol at 25.1℃,respectively.These values were in good agreement with values reported in the literature.
