General description

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.
