摘要 Two reduced sequences of(s/s′)f (relative reduced partition function ratio) found in the present paper are LiSCN·B15C5>LiCCl3COO·B15C5 > LiClO4·B15C5 and LiClO4·4-mB15C5>LiClO4·B15C5>LiClO4·Ph15C5,respectively.These solid lithium complexes with crown ethers were separated from tetrahydrofuran for the first sequence and from 3-methyl-1-butanol for the second one,respectively.Acording to the analysis of the data obtained,an independent character of the three factors(solvents,anion of lithium salts,and the sidegroup of 15C5 series),playing a part in contribution to(s/s′)f,have been brought to light preliminarily. Two reduced sequences of (s/s')f (relative reduced partition function ratio) found in the present paper are LiSCN · B15C5 〉 LiCCl3COO · B15C5 〉 LiClO4 · B15C5 and LiClO4 · 4-mB15C5 〉 LiClO4 · B15C5 〉 LiClO4 · Ph15C5, respectively. These solid lithium complexes with crown ethers were separated from tetrahydrofuran for the first sequence and from 3-methyl-1-butanol for the second one, respectively. Acording to the analysis of the data obtained, an independent character of the three factors ( solvents, anion of lithium salts, and the sidegroup of 15 C5 series ), playing a part in contribution to (s/s')f, have been brought to light preliminarily.
