Description

Naphthenic Acids, Bismuth Salts are specialized organometallic compounds derived from naphthenic acids, a class of carboxylic acids found in petroleum. This product serves as a versatile and effective catalyst, stabilizer, and additive in various high-performance industrial processes. It is particularly valuable for industries requiring precise metal-organic interactions, such as polymer synthesis and specialty chemical manufacturing. The compound, identified by CAS No. 85736-59-0, offers a unique combination of thermal stability and catalytic activity.

Application

• Polymerization Catalyst: Acts as a catalyst or co-catalyst in the production of polyesters, polyamides, and other condensation polymers.
• PVC Stabilizer: Functions as a heat stabilizer in polyvinyl chloride (PVC) formulations to prevent degradation during processing.
• Lubricant Additive: Used as a friction modifier and anti-wear agent in advanced lubricating greases and oils.
• Wood Preservative: Employed in formulations to protect timber from fungal decay and insect infestation.
• Pharmaceutical Intermediate: Serves as a precursor or reagent in the synthesis of certain bismuth-containing active pharmaceutical ingredients (APIs).

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters monitored include bismuth metal content, acid value, viscosity, and solubility. A Certificate of Analysis (COA) detailing purity and specific test results is provided with each shipment and is available upon request. Our quality management system supports customization to meet specific customer and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents, strong acids, and strong bases. The product may be hygroscopic (moisture-sensitive); ensure containers are sealed after use to minimize exposure to atmospheric moisture.
