| 英文摘要 | The co-saturation line for the solid phases NaCl(s) and MgCl2 center dot 6H(2)O((s)) in aqueous solution has been measured by a phase equilibrium at various temperatures. It was found that the Y (b) (Y (b) = w(NaCl)/(w(NaCl) + w(MgCl2))) value of the co-saturation line increase with increasing temperature. A new recrystallization approach has been suggested for the purification of MgCl2 center dot 6H(2)O((s)) containing quite amount of impurity NaCl, i.e., dissolving the crude sample at low temperatures, followed by evaporating and phase separating at high temperatures. Applying the proposed approach a crude MgCl2 center dot 6H(2)O((s)) sample can be purified to the level of Y (b) = 0.17% by only one crystallization process. |
