Product Information
Product Nature
Physical Properties:
· Appearance: White uniform crystalline granules or powder.
· Melting Point: 884°C (begins to decompose at this point).
· Density: Approx. 2.68 g/cm³.
· Solubility: Freely soluble in water, with solubility increasing significantly with temperature (4.76g/100ml at 0°C; 42.7g/100ml at 100°C). Insoluble in ethanol.
· Hygroscopicity: Highly hygroscopic; absorbs moisture from air and gradually converts to sodium sulfate decahydrate (Glauber's salt).Chemical Properties:
· Stability: Chemically stable, non-volatile, and not easily oxidized.
· Acidity/Alkalinity: Aqueous solution is neutral (pH ≈ 7).
· Double Displacement Reaction: Can react with barium, calcium, and lead salts to form corresponding insoluble sulfate precipitates.
· Reaction with Carbon: Can be reduced by carbon at high temperatures to form sodium sulfide.
Product Usage
Synthetic Detergent Industry (Largest Consumer Sector): Used as a filler and builder in laundry detergent powders to prevent caking and aid in detergency.
Paper Industry: Serves as a makeup chemical in the kraft pulping process for chemical and energy recovery from black liquor.
Glass Industry: Acts as a fining agent to help remove bubbles from the glass melt.
Textile Dyeing Industry: Used as a exhausting and leveling agent for dyeing cellulose fibers (like cotton) with direct, sulfur, and vat dyes, improving dye uptake and uniformity.
Pharmaceutical Industry: Used as a laxative (requires pharmaceutical grade) and as a component in fermentation media for producing certain antibiotics (e.g., Vitamin B2).
Chemical Industry: Serves as a raw material for producing sodium sulfide, sodium silicate (water glass), and other chemicals.
Animal Nutrition: Used as a feed additive to supplement sulfur and sodium.
Safety Matters
1. Hazard Identification
GHS Classification: Not generally considered hazardous.
Physical Form: White crystals or powder.
Primary Hazards:
Eye and Skin Irritation: Dust may cause mechanical irritation.
Inhalation Irritation: Dust may cause respiratory irritation.
Prolonged or Repeated Exposure: May cause skin dryness or cracking.
2. First Aid Measures
Inhalation: Remove victim to fresh air. If breathing discomfort occurs, seek medical attention.
Skin Contact: Rinse thoroughly with soap and plenty of water. If irritation occurs, seek medical attention.
Eye Contact: Immediately flush with plenty of running water for at least 15 minutes, holding eyelids open. If irritation persists, seek medical attention.
Ingestion: Drink plenty of water, do not induce vomiting. If you feel unwell, seek medical attention or contact a poison center.
3. Firefighting Measures
Extinguishing Media: This material does not inherently support combustion. Use water, foam, dry powder, or carbon dioxide.
Special Hazards: May decompose at elevated temperatures, releasing toxic sulfur oxide fumes.
Firefighter Protection: In case of fire, wear self-contained breathing apparatus and full protective clothing.
4. Emergency Spill Response
Personal Protection: Wear appropriate dust mask, safety glasses, and gloves.
Handling Methods:
Avoid creating dust. Carefully clean up spilled material and place in a sealed container.
Flush the contaminated area with clean water.
Dispose of collected waste to a qualified disposal company.
5. Handling, Disposal, and Storage
Handling:
Handle in a well-ventilated area.
Use dust control equipment (e.g., local exhaust ventilation).
Avoid generating dust. Prevent dust accumulation in the workplace.
Wash hands thoroughly after handling.
Storage:
Store in a cool, dry, well-ventilated room.
Keep away from incompatible materials (e.g., strong acids).
Keep container tightly closed.
6. Exposure Controls/Personal Protection
Engineering Controls: Provide adequate ventilation to keep dust concentrations below the exposure limit.
Respiratory Protection: If dust concentrations are high, wear a qualified particulate respirator (e.g., N95).
Hand Protection: Wear impermeable gloves.
Eye Protection: Wear safety goggles or dust glasses.
Other Protection: Wear work clothing to avoid repeated or prolonged skin contact.
