甲酸钾（K Formate）是甲酸的钾盐。 它是通过甲酸与氢氧化钾或碳酸钾的中和反应合成的。 已经提出将其作为用于间接制冷系统中的有希望的二次制冷剂。 已经描述了其晶体结构。 据报道其晶体在正交晶系中结晶。
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. It has been proposed as a promising secondary refrigerant for use in indirect refrigeration systems. Its crystal structure has been described. Its crystals have been reported to crystallize in the orthorhombic system.
