甲酸钾，Potassium formate；purum p.a., ≥99.0% (NT)

Potassium formate (K Formate) is the potassium salt of formic acid. It has been synthesized by the neutralization reaction of formic acid with potassium hydroxide or potassium carbonate.[1] It has been proposed as a promising secondary refrigerant for use in indirect refrigeration systems.[2] Its crystal structure has been described. Its crystals have been reported to crystallize in the orthorhombic system.[3]
