Aluminum fluoride Production

The production of Aluminum fluoride (CAS NO.7784-18-1):

Fluoride acid method will come from 18% in phosphate fluoride acid solution heated to about 78 ℃ , then add the reactor with aluminum hydroxide at 100 ℃ for the reaction of aluminum fluoride solution, centrifugation to remove hydrated silicic acid, the filtrate into the crystal device at 90 ℃ under the insulation 3 ~ 5h, have aluminum fluoride trihydrate (AIF3.3H2O) crystals.

After centrifugal separation, the aluminum fluoride trihydrate crystals (moisture 5%) has been dealing with two boiling furnace dehydrated, the first a boiling furnace temperature was controlled at about 205 ℃, first to remove most of the water.
As a result,aluminum fluoride trihydrate the total water content (including crystal water) from 45% to 6% or so, and then in the second fluidized bed furnace in the off the rest of the water, the furnace temperature was controlled at 590 ~ 600 ℃. Dehydrated materials are cooled, the system may anhydrous aluminum fluoride.

H₂SiF₆ +2 AI (OH) ₃ → 2A1F₃+ SiO₂ +4 H₂O

AlF₃ ^. 3H₂O [△] → AlF₃ +3 H₂O

France aluminum hydroxide aluminum hydroxide anhydrous hydrofluoric acid reacts with the aluminum fluoride trihydrate. Then crystallization, filtration, have aluminum fluoride trihydrate.At last by drying (burning) dehydration, obtained anhydrous aluminum fluoride.

AI (OH) ₃ +3 HF → AIF₃^. 3 H₂O

AlF₃ ^. 3H₂O [△] → A1F₃ +3 H₂O
