氯化镁被吸附到含有己酮—１８—冠—６［ＤＣ１８Ｃ６］的有机相中，分配系数表明对于液—液相３．５Ｍ的ＭｇＣｌ２水溶液分离体系的最高值，镁的同位素２４Ｍｇ，２５Ｍｇ及２６Ｍｇ以各的富集因子被富集在该体系中，富集因子２４Ｍｇ／２６Ｍｇ的最大值为∈＝０．０１１２。质量数差值为１的同位素富集因子变化取决于水溶相中ＭｇＣｌ２的浓度，ＤＣ１８Ｃ６的同位素识别能力是Ｋｃ＝１．００１６，比分离系数略小是由于Ｍｇ２＋的水合物与Ｍｇ２＋的二氯基络合物的交换率Ｋｐ＝１．００４０，奇偶同位素作用被观察，其原因是由质量差所决定，由光学跃迁引起的奇／偶交联对于奇／偶质量数的同位素差异行为提供了合适的解释。
Magnesium chloride was adsorbed to the organic phase containing hexanone-18-crown-6 [DC18C6] and the partition coefficient indicated that the highest isotopes of 24 Mg, 25 Mg and 26 Mg for Mg-C solution at 3.5 M in liquid-liquid phase Each enrichment factor is enriched in the system, and the maximum of enrichment factor 24Mg / 26Mg is ∈ = 0.0112. The variation of isotope enrichment factor with a mass difference of 1 depends on the concentration of MgCl2 in aqueous solution. The isotopic discrimination ability of DC18C6 is Kc = 1.0016, which is slightly lower than the separation factor due to the difference between Mg2 + hydrate and Mg2 + The exchange rate of complex is Kp = 1.0040. The effect of odd and even isotopes is observed due to the poor quality. Odd / even cross-linking caused by optical transition provides suitable for the isotope differential behavior of odd / even mass numbers explanation of.
