Basic Information
Produc Name: Sodium Polydisulfide Propane Sulfonate (Abbreviation: SPPS or Na-SPPS)
Structural Formula:C6H12Na2O6S4
CAS Number: 27206-35-5
Appearance: Usually a white to off-white crystalline powder or granules, highly hygroscopic.
Solubility:Highly soluble in water, forming a colorless transparent solution. Insoluble in organic solvents (e.g., ethanol, acetone).
Stability: Stable at room temperature but may decompose under strong acid, strong base, or high-temperature conditions, releasing sulfides. Requires airtight storage to avoid moisture and oxidation.
Chemical Properties
Functional Group Characteristics:
Disulfide Bond (-S-S-): Exhibits redox activity and can participate in thiol (-SH) cross-linking reactions, often used as a cross-linking agent or initiator in polymer synthesis.
Sulfonate Group (-SO3Na): Strong hydrophilicity gives the molecule good water solubility and anionic surface activity, widely used as an additive in electroplating, textiles, etc.
Reactivity:
Can form coordination compounds with metal ions (e.g., copper, nickel, zinc), acting as a leveling and brightening agent in electroplating.
Under acidic conditions, the disulfide bond may break to generate thiol compounds (e.g., 3-mercaptopropane sulfonate).
Application Fields
1. Electroplating Industry (Primary Application)
Role: Serves as a brightener, leveling agent, and leveling agent in acidic copper plating, nickel plating, zinc plating, and other processes.
Mechanism:
Adsorbs on the metal surface to inhibit rough crystal growth, improving coating gloss and uniformity.
Compounds with other organic additives (e.g., sulfur-containing compounds, polyethers) to optimize coating performance.
Advantages: Low toxicity, environmentally friendly, replacing traditional cyanide or heavy metal-containing electroplating additives.
2. Polymer Synthesis
Use: As a polymer cross-linking agent or initiator for preparing sulfur-containing polymer materials (e.g., polysulfide rubber, hydrogels).
Example: In free radical polymerization, disulfide bonds act as chain transfer agents to regulate polymer molecular weight and structure.
3. Pharmaceuticals and Biotechnology
Potential Applications:
As a thiol cross-linking agent in bioconjugation chemistry for protein or antibody immobilization.
As a surface modifier for drug carriers (e.g., nanoparticles) to enhance water solubility and targeting.
4. Other Fields
Textile Dyeing: As a leveling agent or antistatic agent to improve dye dispersibility and fabric hand feel.
Water Treatment: Chelates and removes heavy metal ions (e.g., Hg², Ag) by forming stable complexes with metals via disulfide bonds.
Safety and Storage
Toxicity: Low toxicity but irritating to skin and eyes; avoid direct contact.
Storage Conditions:
Store in a cool, dry place in a sealed container, away from oxidizing agents, strong acids, and strong bases.
Use promptly after opening to prevent moisture absorption and caking.
Environmental Friendliness: Biodegradable, with low environmental hazard, but avoid large-scale discharge into water bodies.
