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.[9]
