MERCURY(I) FLUORIDE Chemical Properties,Uses,Production
Description
Mercury(I) fluoride or mercurous fluoride, Hg2F2, consists of small yellow cubic crystals, which turn black when
exposed to light. Mercury(I) fluoride is formed by the reaction of mercury(I) carbonate with hydrofluoric acid.
Hg2CO3 + 2HF→Hg2F2 +CO2 +H2O
Chemical Properties
small, yellow cub crystal(s); blackens in light; preparation by reaction of Hg2CO3 and HF [MER06]
Uses
Mercury(I) fluoride is used as antiseptic. It is used in the Swarts reaction to convert alkyl halides into alkyl fluorides.
Preparation
The wet Hg2CO3 is added in small portions and with constant stirring to 40% hydrofluoric acid solution contained in a platinum dish. A yellow powder of Hg2F2 settles out. The addition of Hg2CO3 is continued as long as CO2 is vigorously evolved; the highly dilute supernatant hydrofluoric acid is then poured off and a new portion of 40% hydrofluoric acid solution is added. The resulting mixture is evaporated to dryness on a water bath. The product is then pulverized and heated for 2-3 hours in a drying oven at 120-150°C. The product is then immediately poured into copper containers and vacuum-sealed.
