METHOD FOR PURIFICATION OF ALKALINE METALS IODIDES FROM ADMIXTURES OF ORGANIC COMPOUNDS

The essence of the method consists in loading salt into the ampoule, vacuum compaction thereof to the pressure of 10-3 mm of mercury, gradual heating the salt at the rate of 20-50 DEGREE C per hour from the room temperature to the temperature of 420+- 20 DEGREE C with maintaining constant pressure i...

Beschreibung
Zusammenfassung:	The essence of the method consists in loading salt into the ampoule, vacuum compaction thereof to the pressure of 10-3 mm of mercury, gradual heating the salt at the rate of 20-50 DEGREE C per hour from the room temperature to the temperature of 420+- 20 DEGREE C with maintaining constant pressure in the ampoule at the level of 10-3 mm of mercury. A method for purification of alkaline metals iodides from organic compounds admixtures provides decreasing power inputs and do not promote an increase of the concentration of compounds with oxygen content.
