Tetrafluoroborate → HCID 131732340, compound

Participants

Reaction Steps

1,162 grams of a 20% solution of sodium tetrafluoroborate in water was heated to about 50° C. With agitation, 379 grams of an 80% aqueous solution of 2-(methylacryloyloxy)ethyl trimethylammonium methylsulfate (Sigma-Aldrich) was slowly mixed with the tetrafluoroborate solution. The solution was allowed to cool without agitation to room temperature and was then stored in a refrigerator overnight. On the following day, a white solid was filtered from the solution and then dried under vacuum for about 24 hours. 217 grams of dry 2-(methylacryloyloxy)ethyl trimethylammonium tetrafluroborate was collected.
