Title:
PROCESS FOR PRODUCING FLUORINE-CONTAINING COMBINED SALT
Document Type and Number:
WIPO Patent Application WO/2012/144383
Kind Code:
A1
Abstract:
Disclosed is a process for producing a fluorine-containing combined salt, characterized by comprising allowing a trigger capable of accelerating the decomposition of a fluoroanion to act on a reaction mother liquor comprising multiple types of cations and a fluoroanion dissolved in a solvent, thereby precipitating a combined salt containing the multiple types of cations and fluorine as a solid from the reaction mother liquor. The process enables the production of a mono-dispersed fluorine-containing combined salt having a uniform particle size and a uniform particle shape.
