Potassium formate is a colorless transparent liquid or white solid, easy to absorb moisture, has reducibility, can react with strong oxidants, density of 1.9100g/cm3, soluble in water, saturated chemicalbook and solution specific gravity of 1.58g/cm3, non-toxic and non-corrosive. Potassium formate can be synthesized by heating carbon monoxide with potassium hydroxide, which is further acidified and distilled to obtain formic acid.
