Aluminium fluoride trihydrate → HCID 22044322, compound

Participants

Reaction Steps

6.90 g (50.0 mmol) of aluminum fluoride trihydrate was weighed and placed in a round flask made of PFA, and air in the flask was evacuated and then replaced by argon gas. While feeding argon gas to the flask through its inlet, 100 ml of dehydrated acetonitrile was added and the flask was sealed followed by stirring for 30 minutes. Then, while feeding argon gas similarly, 9.46 g (50.0 mmol) of triethylmethylammonium fluoride trihydrate was added portion wise, and the resultant mixture was further stirred for about 3 hours. The unreacted solid was filtered off, and then the solvent was distilled off to obtain about 9 g of white crude crystal of triethylmethylammonium tetrafluoroaluminate. This was subjected to recrystallization from 10 g of isopropanol. The amount of the product was 5.50 g, and the yield was 50% based on the charged raw material. Identification was made by elemental analysis and NMR, and a melting point was measured by TG-DTA.
