    Sodium Formate CAS 141-53-7

    Sodium Formate CAS 141-53-7 is a highly soluble organic salt chemically defined as the sodium salt of formic acid , functioning primarily as a camouflage acid in the leather tanning industry and a non-corrosive de-icing agent for airport runways. Also known as Sodium methanoate or Formic acid sodium salt, this white crystalline powder is utilized to assist in the chrome penetration of leather hides (pickling) and acts as a high-density, environmentally benign additive in drilling fluid brines. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

    Key Application Areas

    Sodium Formate is a multi-industry utility player. Here is where it shines:

    1. The Leather Industry (Camouflage Acid) This is perhaps its most traditional and vital use. In the chrome tanning process, Sodium Formate acts as a masking agent. It assists in the uniform penetration of chrome into the leather. Without it, the tanning can be uneven, leading to poor quality hides. It helps stabilize the pH, ensuring the leather is soft, durable, and uniform in color.

    2. Eco-Friendly De-icing and Snow Melting As environmental regulations tighten, the shift away from chloride-based salts is accelerating. Sodium Formate is an excellent de-icer for airport runways and city bridges because it is effective at low temperatures and, crucially, it is non-corrosive to concrete and metals compared to traditional salts. It breaks down quickly, reducing environmental impact.

    3. Oil and Gas Exploration In the drilling sector, Sodium Formate is used in saturated formats to increase the density of drilling fluids (muds) and completion fluids. It stabilizes the borehole and is much friendlier to the drilling equipment (preventing corrosion) and the environment than traditional brines.

    4. Textile and Fabric Processing It serves as a reducing agent in the printing and dyeing industry. It also acts as a buffering agent to maintain pH levels during various fabric treatments.

    5. Chemical Synthesis It is a raw material for manufacturing other chemicals, including formic acid, oxalic acid, and sodium hydrosulfite.

    Safety and Precautionary Measures

    While Sodium Formate is generally considered less hazardous than many industrial acids, it must still be handled with respect and care.

    • Respiratory Protection: It is a fine powder. Inhalation of dust can irritate the respiratory tract. Always use appropriate dust masks or respirators in well-ventilated areas.
    • Skin and Eye Contact: It acts as a mild irritant. Wear protective gloves and safety goggles. If contact occurs, flush with plenty of water immediately.
    • Ingestion: Do not ingest. It is low in toxicity but can cause gastrointestinal irritation.

    Always refer to the latest Material Safety Data Sheet (MSDS/SDS) before handling.

    Storage and Handling Conditions

    Because Sodium Formate is hygroscopic (it loves water), storage is the most critical part of logistics.

    1. Keep it Dry: It must be stored in a cool, dry, and well-ventilated area.
    2. Sealed Packaging: Bags should remain tightly sealed until use. Typical packaging includes PE-lined woven bags (25kg) or Jumbo bags (1000kg) to prevent moisture ingress.
    3. Segregation: Store away from strong acids and oxidizing agents to prevent chemical reactions.

    FAQ - Technical & Supply Chain

    • Q:

      Why is Sodium Formate (CAS 141-53-7) preferred over chloride salts for critical de-icing applications?

      A: Unlike common rock salt (sodium chloride) or calcium chloride which are highly corrosive to metals and asphalt, Sodium Formate (CAS 141-53-7) exhibits a significantly lower corrosion profile. This chemical property makes it the industry-standard specification for de-icing airport runways and steel bridges where preserving structural integrity and meeting environmental biodegradability standards is mandatory.
    • Q:

      Can this grade be utilized as a "buffering agent" in the leather tanning process?

      A: Yes. In the leather industry, Sodium Formate acts as a "camouflage acid."It is added during the pickling and chrome tanning stages to buffer the strong mineral acids (like sulfuric acid), raising the pH gradually. This controlled pH elevation prevents the surface of the hide from tightening too quickly ("drawn grain"), ensuring uniform penetration of the chrome tanning agents throughout the cross-section of the leather.
