METHOD FOR PREPARATION OF MANGANESE FLUORIDE Russian patent published in 2009 - IPC C01G45/06 C01B9/08 

FIELD: chemistry.

SUBSTANCE: invention can be used for preparation of manganese fluoride used in the production of gaseous fluorine. The method of manganese fluoride preparation includes the stage (1) of the manganese interreaction with fluorinating agent in temperature range from 50 to 250 °C and the stage (2) of the further interreaction of the product obtained at stage (1) with fluorinating agent in temperature range from 250 to 450 °C. The manganese compound is at least one compound selected from the group consisting of MnF₂, MnCO₃, MnO and their hydrates. The fluorinating agent is at least one compound selected from the group consisting of F₂, ClF and ClF₃. The manganese fluoride obtained in the aforesaid process is MnF_x (x = 3 ÷ 4).

EFFECT: invention allows to simplify the manganese fluoride preparation, to decrease the temperature of the process and to exclude the stages of sublimation and solidification.
