Abstract

The crystallization enthalpies of MgCl2 in MgCl2−H2O-cosolvent systems at 25°C were determined calorimetrically as a function of the cosolvent content in the mixed solvent. Methanol, acetone, and N,N-dimethylformamide were employed as cosolvents. The results show the individual cosolvents to have very differently influences on the energy state of the salt in the saturated solution. The most pronounced changes are effected by an increase of the DMF content in the mixed solvent. The intensity of Mg2+-DMF interaction at a higher DMF content in the saturated solution considerably exceeds the Li+-DMF interaction in LiCl solutions.
