Conclusions
-
1.
The methods of differential-thermal and visual-polythermal analyses and isothermal solubility were used to study the reaction in the system KAlH4-diglyme (DG) in the temperature range from −64 to +50°.
-
2.
The existence of the solvates KAlH4-4DG and KAlH4-3DG was established, and the crystallization region of the unsolvated KAlH4 and the melting point of pure diglyme were determined.
