Abstract
FIELD: inorganic reagents. SUBSTANCE: interaction of powder-like lithium fluoride and gaseous boron trifluoride is carried out in the presence of fluorine at the volume ratio of boron trifluoride and fluorine 1:(0.05-0.2), at 70-250 C, under pressure 0.35-2.5 MPa. Yield of product is 96.3-98.7% , duration of process is 500-600 s. Lithium tetrafluoroborate can be used as ionogenic salt for anhydrous electrolytes of chemical current sources, as a reagent for boron trifluoride preparing and catalyst of polymerization reaction. EFFECT: increased yield of lithium tetrafluoroborate, enhanced output of process. 3 tbl
