Potassium formate has also been studied as a potential environmentally friendly deicing salt for use on roads.

Potassium formate is the potassium salt of formic acid.

Reductive amination of aldehydes or ketones using potassium formate.

Potassium formate (CHOK)

It also arises by fusing potassium meta-sulphobenzoate, or meta-brombenzoate with potassium formate (terephthalic acid is also formed in the last case).

Many other chemicals (e.g. potassium formate) are added to a WBM system to achieve various effects, including: viscosity control, shale stability, enhance drilling rate of penetration, cooling and lubricating of equipment.

In 1822, Serullas added potassium metal to a solution of iodine in ethanol and water to form potassium formate and iodoform, called in the language of that time hydroiodide of carbon.
