Sodium formate

Sodium formate is a white granules. Sodium formate is an organic sodium salt which is the monosodium salt of formic acid.
  • sodium salt, sodium hydrocarbon dioxide
  • white granules
  • 141-53-7
  • HCOONa
  • insoluble in ether, soluble in glycerol, alcohol, formic acid



Sodium formate, also known as sodium formate.Sodium formate is one of the simplest organic carboxylates. Its appearance is white crystals or powder with a slight formic acid odor.Slightly hydrolytic and hygroscopic.Sodium formate is mainly used for the production of insurance powder, oxalic acid, and formic acid.Sodium formate can be used in the leather industry as a camouflage acid in the chromium leather process. It also can be used for the catalyst and stabilizing the synthesis agent, a reducing agent in the printing and dyeing industry.Sodium formate is harmless to the human body and stimulates the eyes, respiratory system and skin.



printing industry

Sodium formate is used in several fabric dyeing and printing processes. It is also used as a buffering agent for strong mineral acids to increase their pH, as a food additive (E237), and as a de-icing agent.

structural biology

In structural biology, sodium formate can be used as a cryoprotectant for X-ray diffraction experiments on protein crystals, which are typically conducted at a temperature of 100 K to reduce the effects of radiation damage.

non-corrosive agent

Solid sodium formate is used as a non-corrosive agent at airports for de-icing of runways in mix with corrosion inhibitors and other additives, which rapidly penetrate solid snow and ice layers, detach them from the asphalt or concrete and melt the ice rapidly. Sodium formate was also used as a road deicer in the city of Ottawa from 1987 to 1988.

Other uses

The high freezing point depression e.g. in comparison to the still frequently used urea (which is effective but problematic due to eutrophication) effectively prevents the re-icing, even at temperatures below −15 °C. The thawing effect of the solid sodium formate can even be increased by moistening with aqueous potassium formate or potassium acetate solutions. The degradability of sodium formate is particularly advantageous with a chemical oxygen demand (COD) of 211 mg O2/g compared with the de-icing agents sodium acetate (740 mg O2/g) and urea with (> 2,000 mg O2/g).



Sodium formate is usually packaged in 25kg plastic lined compound bags.

Sodium formate usually store in a cool, dry, well-ventilated place to avoid direct sunlight, away from heat source, acid, water, moist air.
