Sodium formate, HCOONa, is the sodium salt of formic acid, HCOOH.
Sodium Formateusually appears as a white deliquescent powder.
Preparation
For commercial use, sodium formate is produced by absorbing carbon monoxide under pressure in solid sodium hydroxide at 130 °C and 6-8 bar pressure:
CO + NaOH → HCO2Na
Because of the low-cost and large-scale availability of formic acid by carbonylation of methanol and hydrolysis of the resulting methyl formate, sodium formate is usually prepared by neutralizing formic acid with sodium hydroxide.
Sodium formate is also unavoidably formed as a by-product in the final step of the pentaerythritol synthesis and in the crossed Cannizzaro reaction of formaldehyde with the aldol reaction product trimethylol acetaldehyde [3-hydroxy-2,2-bis(hydroxymethyl)propanal].
In the laboratory, sodium formate can be prepared by neutralizing formic acid with sodium carbonate.
Sodium Formatecan also be obtained by reacting chloroform with an alcoholic solution of sodium hydroxide.
CHCl3 + 4 NaOH → HCOONa + 3 NaCl + 2 H2O
or by reacting sodium hydroxide with chloral hydrate.
C2HCl3(OH)2 + NaOH → CHCl3 + HCOONa + H2O
The latter method is, in general, preferred to the former because the low aqueous solubility of CHCl3 makes it easier to separate out from the sodium formate solution, by fractional crystallization, than the soluble NaCl would be.
Sodium formate may also be created via the haloform reaction between ethanol and sodium hypochlorite in the presence of a base.
This procedure is well documented for the preparation of chloroform.
Properties
Physical properties
Sodium formate crystallizes in a monoclinic crystal system with the lattice parameters a = 6,19 Å, b = 6,72 Å, c = 6,49 Å and β = 121,7°.
Chemical properties
On heating, sodium formate decomposes to form sodium oxalate and hydrogen.
Uses
Sodium formate is used in several fabric dyeing and printing processes.
Sodium Formateis 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.
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.
Sodium formate is converted with sulfuric acid to formic acid and sodium sulfate.
The urticating hair of stinging nettles contain sodium formate as well as formic acid.
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.
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).
Saturated sodium formate solutions (as well as mixtures of other alkali metal formates such as potassium and cesium formate) are used as important drilling and stabilizing aids in gas and oil exploration because of their relatively high density.
By mixing the corresponding saturated alkali metal formate solutions any densities between 1,0 and 2,3 g/cm3 can be set.
The saturated solutions are biocidal and long-term stable against microbial degradation.
Diluted, on the other hand, they are fast and completely biodegradable.
As alkali metal formates as drilling aids make it unnecessary to add solid fillers to increase the density (such as barytes) and the formate solutions can be recovered and recycled at the drilling site, formates represent an important advance in exploration technology.
