Preparation of Ammonium formate: this chemical can be prepared by formic acid and NH3 via neutralization reaction. The formic acid and H2O is freezed. The reaction mixture is stirred at -5 °C with the PH value of 7-7.5 and is filtered. Finally, you can get Ammonium formate.

Ammonium formate can be prepared by formic acid and NH3 via neutralization reaction

Uses: formic acid can be obtained by reacting Ammonium formate with a dilute acid, and since ammonium formate is also produced from formic acid, it can serve as a way of storing formic acid. Ammonium formate can also be used in palladium on carbon (Pd/C) reduction of functional groups. Ammonium formate can be used for reductive amination of aldehydes and ketones. Ammonium formate can be used as a buffer in high performance liquid chromatography (HPLC), and is suitable for use with liquid chromatography/mass spectroscopy (LC/MS).

When you are using this chemical, please be cautious about it as the following:
