Stannous Oxalate CAS 814-94-8

Stannous Oxalate (CAS 814-94-8) is an organometallic tin compound serving as an effective esterification catalyst in chemical synthesis and a reducing agent in textile dyeing processes. Chemically identified as Tin(II) oxalate or Oxalic acid tin(II) salt, this white to off-white crystalline powder functions to accelerate polymerization reactions and stabilize colorants in fabric treatments. As a specialized Ethanedioic acid tin(II) salt derivative, it is widely utilized in the production of plasticizers and ester-based lubricants due to its high catalytic activity and selectivity. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific purity and particle size requirements. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

Product Description

Stannous Oxalate is an organic salt of tin. Unlike liquid organotin catalysts, it is a solid powder that provides distinct advantages in specific polymerization processes.

Main Characteristics:

High Catalytic Efficiency: It significantly speeds up esterification and polycondensation reactions at lower temperatures compared to non-tin catalysts.
Color Stability: One of its primary benefits is that it minimizes “color reversion” or yellowing in the final polymer or plasticizer, making it ideal for high-quality, clear end-products.
Solubility: While practically insoluble in water, it dissolves readily in dilute acids, making it adaptable for various chemical processing environments.

Applications

Esterification Catalyst: Extensively used in the production of plasticizers (e.g., Dioctyl Phthalate) and polyesters. It promotes the reaction between acids and alcohols without degrading the color of the resin.
Coal Hydrogenation: Used as a catalyst in the coal liquefaction process (gasification) to improve efficiency.
Textile Industry: Acts as a mordant in textile dyeing and printing processes.
Glass & Ceramics: Sometimes used as a reducing agent or additive in specialized glass formulations.
Electroplating: Used in certain acidic tin plating baths.

Storage Conditions

Environment: Store in a cool, dry, and well-ventilated area.
Container: Keep the container tightly closed. This product can be slightly hygroscopic; protect from moisture to prevent clumping.
Incompatibility: Store away from strong oxidizing agents and alkalis.
Shelf Life: 12 months in original unopened packaging under proper conditions.

Safety Precautions

Handling: Harmful if swallowed or inhaled. Stannous Oxalate may cause skin and eye irritation. Use only with adequate ventilation.
PPE: Wear chemical-resistant gloves, safety goggles, and a dust mask/respirator during handling.
Ingestion: If swallowed, rinse mouth and seek medical attention immediately.
First Aid:
- Skin: Wash with plenty of soap and water.
- Eyes: Rinse cautiously with water for several minutes.
Disposal: Tin compounds should be disposed of according to local environmental regulations; do not release into watercourses.
