| | Potassium formate Usage And Synthesis |
| Description | Potassium formate is a useful chemical compound in the production of potassium metal and in the oil and gas industry, often in aqueous solution (alone, or mixed with cesium formate), to yield a high-density, environmentally-friendly brine that can be used a a heat transfer fluid. Potassium formate is available as both a solid and in solution form. | | Uses | Potassium formate (potassium salt of formic acid), an organic acid used as a drilling fluid additive, was treated using EK. It is mainly used for preparation of an aqueous solution filling the well, in foreign country, potassium formate began to be used in drilling and completion fluids in 1990s, it is especially used in high-density drilling and completion fluid system, and achieved good results. Drilling fluid system which formulated with potassium formate has outstanding advantages of strong inhibition, good compatibility, environmental protection, reservoir protection. Field application results shows that potassium formate can inhibite clay water divide.

| | Description | Potassium formate is the potassium salt of formic acid. It is an intermediate in the formate potash process for the production of potassium . Potassium formate has also been studied as a potential environmentally friendly deicing salt for use on roads. | | Chemical Properties | white crystalline solid | | Uses | Reducing agent; secondary refrigerant; anti-oxidant in oil drilling applications. | | Uses | Potassium formate acts as an intermediate in the formate potash process for the production of potassium. It is a deicing salt for used on roads. It serves as a corrosion inhibitor, an anti-scaling agent, a functional fluid, a processing aid and used in petroleum production. | | Definition | ChEBI: The potassium salt of formic acid. | | 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. | | Flammability and Explosibility | Notclassified |
