1. Chemical Properties and Production of Sodium Bifluoride
Sodium bifluoride (NaHF₂) is a white, crystalline solid known for its high solubility in water and ability to release hydrofluoric acid (HF) upon dissolution. Its chemical structure consists of sodium ions (Na⁺) paired with bifluoride anions (HF₂⁻), making it a versatile compound in industrial processes.
Key Chemical Characteristics:
Molecular Formula: NaHF₂
Molar Mass: 61.99 g/mol
Melting Point: Decomposes at approximately 160°C, releasing hydrogen fluoride gas.
Solubility: Highly soluble in water, forming acidic solutions that are effective in cleaning and etching applications.
Reactivity: Reacts with strong acids to produce HF gas, necessitating careful handling.
Production Process:
At Nantong Jinxing Fluorides Chemical Co., Ltd., sodium bifluoride is manufactured through a controlled neutralization process. High-purity hydrogen fluoride (HF) is reacted with sodium carbonate (Na₂CO₃) or sodium hydroxide (NaOH) under precise conditions to ensure optimal yield and purity. The resulting solution is then crystallized, dried, and milled into a fine powder, meeting industry standards for quality and consistency.
Our advanced production facilities and strict quality control measures ensure that Jinxing Fluorides delivers sodium bifluoride with minimal impurities, making it ideal for demanding industrial applications. Over the past 50 years, we have refined our manufacturing techniques to enhance efficiency while maintaining environmental responsibility.
