Sodium Formate 98%

Product Overview

Sodium formate is a high-purity white crystalline powder, an organic acid salt. As an important basic chemical raw material, it plays a key role in numerous industrial fields—including leather tanning, textile printing and dyeing, chemical synthesis, environmentally friendly snow-melting, and construction additives—thanks to its excellent reducing properties, buffering capacity, and eco-friendly biodegradability. The product strictly complies with the HG/T 5390-2018 industrial-grade standard, with a main content ≥98.0%, controllable impurity levels, and high batch-to-batch consistency, meeting the stringent requirements of industrial production across various sectors.

Technical Principle

The core technical principle of sodium formate (chemical formula HCOONa, also known as sodium methanoate) is based on its three key chemical characteristics. First is its reducing property, which allows it to serve as a reducing agent in textile printing and precious metal recovery. At high temperatures, it decomposes into sodium oxalate and hydrogen gas, subsequently forming sodium carbonate, thereby fulfilling specific chemical reduction needs. Second is its buffering capacity: its aqueous solution exhibits weak alkalinity, with a pH of approximately 7.5 to 8.5 for a 10% solution, enabling correction of strong acid pH levels and facilitating the formation of trivalent metal complex ions in solution, thus maintaining stable acidity–alkalinity within reaction systems. Lastly, its eco-friendly biodegradability makes it an ideal alternative to traditional chloride-based de-icing agents; the product is fully biodegradable and does not impose a lasting environmental burden.
