Sodium formate is an organic sodium salt salt of formic acid. Sodium formate is stable and it is Incompatible with strong oxidizing agents, strong acids. Protect from moisture. It is water soluble and hygroscopic in nature. It usually appears as a white deliquescent powder. Sodium formate is used in several fabrics 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.
Sodium Formate Process and Uses:
For business utilize, sodium formate is delivered by retaining carbon monoxide under strain in strong sodium hydroxide at 130 °C and 6-8 bar pressure:
CO + NaOH → HCO2Na
Due to the minimal effort and extensive scale accessibility of formic corrosive via carbonylation of methanol and hydrolysis of the subsequent methyl formate, sodium formate is normally arranged by killing formic corrosive with sodium hydroxide. Sodium formate is likewise unavoidably framed as a result in the last advance of the pentaerythritol blend and in the crossed Cannizzaro response of for
maldehyde with the aldol response item trimethylol acetaldehyde [3-hydroxy-2,2-bis(hydroxymethyl)propanal].
In the research facility, sodium formate can be set up by killing formic corrosive with sodium carbonate. It can likewise be acquired by responding chloroform with a heavy drinker arrangement of sodium hydroxide.
CHCl3 + 4 NaOH → HCOONa + 3 NaCl + 2 H2O
or then again by responding sodium hydroxide with chloral hydrate.
C2HCl3(OH)2 + NaOH → CHCl3 + HCOONa + H2O
The last technique is, all in all, wanted to the previous in light of the fact that the low watery dissolvability of CHCl3 makes it less demanding to isolate out from the sodium formate arrangement, by partial crystallization, than the solvent NaCl would be.Sodium formate may likewise be made by means of the haloform response among ethanol and sodium hypochlorite within the sight of a base. This methodology is all around archived for the readiness of chloroform.
