Potassium formate, HCO2K, HCOOK, or KHCO2, is the potassium salt of formic acid. This strongly hygroscopic white solid [2] is an intermediate in the formate potash process for the production of potassium. [3] Potassium formate has also been studied as a potential environmentally friendly deicing salt for use on roads. [4] [5] It has also been suggested for use in a less corrosive liquid desiccant. [6] A 52% solution of potassium formate has a freezing point of −60 °C (−76 °F). [7] Potassium formate brines are sometimes used for heat transfer, despite being much more corrosive than many other liquid coolants, especially to zinc and aluminum but even to many steels, [8] though some formulations are compatible with aluminum and steels.
