Sodium formate is a multifunctional organic acid salt that combines reducing properties with buffering capacity. As a basic chemical raw material, it is widely used in environmental snow-melting, leather tanning, textile printing and dyeing, and chemical synthesis, among other applications.

Sodium Formate

Product Overview

Sodium formate is a multifunctional organic acid salt that combines reducing and buffering properties. Also known as sodium methanoate, its chemical formula is HCOONa, and it serves as an important basic chemical raw material. Thanks to its unique chemical characteristics, it plays an irreplaceable role in various fields such as environmentally friendly snow melting, leather tanning, textile dyeing and printing, and chemical synthesis. It not only meets the differentiated functional needs of different industries but also aligns with the trend of green chemistry development.

Technical Principle

The core technical principle of sodium formate is based on its three key chemical properties: First, its reducing ability allows it to be oxidized into sodium carbonate, making it suitable as a reducing agent in dyeing and precious metal recovery to facilitate specific chemical reactions; second, its buffering capacity gives its aqueous solution a weakly alkaline nature—with a pH value between 7.5 and 8.5 for a 10% solution—effectively maintaining stable acidity or alkalinity in reaction systems and preventing fluctuations that could affect reaction outcomes; third, its environmentally friendly degradability makes it an ideal alternative to traditional chloride-based de-icing agents. The product is biodegradable, with a BOD₅/COD ratio greater than 0.5, thus avoiding long-term environmental burdens. Additionally, at high temperatures, sodium formate decomposes into sodium oxalate and hydrogen gas, which further generates sodium carbonate, expanding its application scope in chemical synthesis.

Performance Parameters

1. Appearance and Solubility: White crystalline powder or granules with a slight formic acid odor, readily soluble in water—at 20°C, solubility reaches 97 g/100 mL—soluble in glycerol, slightly soluble in ethanol, and insoluble in ether. Melting point is 253°C, which also corresponds to its decomposition temperature, with a density of approximately 1.429 g/cm³.
2. Purity Grades: Industrial grade purity ranges from ≥96.0% to ≥99.0%; food-grade purity is ≥99.0%. Premium products meet both HG/T 5390-2018 industrial standards and GB/T 23672-2009 national standards.
3. Impurity Control: For industrial-grade products, moisture content is ≤0.5% to 1.0%, chloride (Cl⁻) ≤0.05% to 0.1%, and heavy metals (expressed as Pb) ≤10 ppm. Analytical-grade impurities are even more strictly controlled, with chloride ≤0.002% and heavy metals ≤0.0005%.
4. Snow-Melting Performance: As an eco-friendly de-icing component, sodium formate can lower the freezing point down to −21.3°C. Its solid particle size can be adjusted between 0.15 mm and 9 mm, exhibiting good flowability without hardening, and demonstrating superior dissolution speed and snow-melting efficiency compared to sodium chloride.
