Sodium formate HCOONa, also known as sodium methanoate, is the sodium salt of formic acid. It is a white, water-soluble crystalline powder with hygroscopic properties. Sodium formate is widely used in various industries, including leather tanning, oil drilling, de-icing, and as a reducing agent in chemical processes. In the leather industry, it is commonly used to reduce hexavalent chromium (Cr⁶⁺) to trivalent chromium (Cr³⁺), making it safer for environmental discharge.
Method 1: Reaction of Formic Acid with Sodium Hydroxide
Sodium formate is typically produced by neutralizing formic acid (HCOOH) with sodium hydroxide (NaOH) or sodium carbonate (Na₂CO₃):
HCOOH + NaOH → HCOONa + H₂O
HCOOH + Na₂CO₃ → 2HCOONa + CO₂ + H₂O
This method results in high-purity sodium formate and is widely used in commercial production.
Method 2: By-Product of Pentaerythritol Production*
Sodium formate is also obtained as a by-product in the manufacturing of pentaerythritol, a key ingredient in alkyd resins and explosives. The process involves reacting formaldehyde with sodium hydroxid in the presence of excess methanol, yielding sodium formate as a secondary product.
