Product Description

Product Description

Basic Information

• Chemical Name: Pentasodium diethylenetriaminepentaacetate
• Molecular Formula: C14H18N3Na5O10
• Molecular Weight: Approximately 503.26 g/mol
• CAS Number: 140-01-2
• Synonyms: Pentasodium salt of DTPA, Pentasodium pentetate

Physical Properties

• Appearance: Usually a light yellow transparent liquid.
• Solubility: Highly soluble in water.
• pH Value: Aqueous solutions are strongly alkaline, typically ranging from 10.5 to 13.5.
• Storage Stability: Color may darken slightly during long-term storage, but chemical properties remain stable under normal conditions.

Chemical Characteristics

• Chelating Ability: Exhibits strong chelating properties, forming water-soluble complexes with various metal ions, including Ca², Mg², Fe³, Pb², Cu², and Mn².
• High-Efficiency Complexation: Particularly effective for chelating high-valent and chromogenic metal ions, forming stable complexes that prevent their catalytic or interfering effects in various processes.

Main Applications

1. Bleaching Stabilizer for Hydrogen Peroxide
   • Used in textile and paper pulp bleaching to chelate metal ions, preventing the catalytic decomposition of H2O2. This reduces bleaching costs and protects cellulose from oxidative damage.
2. Water Softener
   • Removes calcium and magnesium ions from water to prevent scale formation, maintaining long-term chelating capacity for sustained softening effects.
3. Textile and Dyeing Auxiliary
   • Chelates hardness ions and other metal ions that may interfere with dyeing, ensuring uniform coloration, enhancing dye brightness, and reducing dye waste.
4. Analytical Reagent and Chelometric Titrant
   • Serves as a standard reagent in analytical chemistry for the titration and quantification of metal ions due to its reliable chelating performance.

Packaging and Storage

• Packaging: Commonly supplied in 250 kg plastic drums.
• Storage Conditions: Store in a cool, dry place away from direct sunlight and moisture.

Safety Considerations

• As a strong alkaline solution, it may cause skin/eye irritation; proper protective equipment (gloves, goggles) is recommended during handling.
• Follow standard industrial safety practices for storage and disposal.

Pentasodium DTPA is widely valued for its efficient chelating properties, making it essential in industries ranging from textiles and papermaking to water treatment and analytical chemistry
