Chemistry
Uses
2. Strong mineral acids use it as buffering agent to increase PH.
Production
1. Reacting chloroform with an alcoholic solution of sodium hydroxide produces sodium formate; neutralizeing formatic acid with sodium carbonate also produces Sodium formate. The formular is as following:
CHCl3 + 4NaOH → HCOONa + 3NaCl + 2H2O
2. by reacting sodium hydroxide with chloral hydrate:
2HCl3(OH)2 + NaOH → CHCl3 + HCOONa + H2O
The latter method is better than the former, since the low aqueous solubility of CHCl3 makes it easier to separate out from the sodium formate solution than the soluble NaCl would be by fractional crystallization.
3. The commercial way to produce sodium formate is to bsorbing carbon monoxide under pressure in solid sodium hydroxide at 160 °C, showing below:
CO + NaOH → HCOONa
