METHOD OF OBTAINING POTASSIUM TRIFLUORIDE Russian patent published in 2008 - IPC C01D3/02 

Abstract RU 2331584 C1

FIELD: chemistry.

SUBSTANCE: to obtain potassium trifluoride, potassium fluoride is saturated with hydrogen. The potassium containing raw materials and the fluorinating agent are mixed in stoichiometric propotions and the obtained mixture is heated in a temperature interval of 75-240°C. The fluorinating agent used is ammonium fluoride or ammonium bifluoride, or their mixture.

EFFECT: invention allows obtaining potassium trifluoride without use of toxic hydrogen fluoride.
