Chemical Name: Di-N-Propyl Peroxydicarbonate
Formula: C8H14O6
Synonyms: Peroxydicarbonic acid, di-n-propyl ester
Physical State: Usually found as a liquid or oily substance, often colorless to pale yellow
Odor: Mild, sometimes sweet smell
CAS Number: 26322-14-5
GHS Classification: Organic Peroxide, Type D; Acute Toxicity, Oral, Category 4; Skin Sensitization, Category 1
Hazard Statements: Heating can cause an explosion. May cause skin and eye irritation. Harmful if swallowed.
Pictograms: Flame over circle, exclamation mark
Routes of Exposure: Inhalation, Ingestion, Skin, Eyes
Possible Effects: Headache, dizziness, skin rash, burns, gastrointestinal distress
Main Component: Di-N-Propyl Peroxydicarbonate up to 100 percent
Impurities: May contain traces of stabilizers or solvents (types and concentrations vary).
Inhalation: Move affected person to fresh air immediately. Loosen tight clothing. Seek medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing. Wash affected area thoroughly with soap and water for at least 15 minutes. If irritation develops, consult a doctor.
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes, holding eyelids open. Remove contact lenses if safe to do so. Medical attention without delay.
Ingestion: Do not induce vomiting. Rinse mouth with water if conscious. Get medical help as soon as possible.
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide (CO2). Never use direct water stream on burning material.
Fire Hazards: Organic peroxides like this one break down violently under heat. Risk of explosion exists if heated or caught in a fire.
Protective Equipment: Use self-contained breathing apparatus and full protective gear. Keep away from incompatible materials.
Firefighting Advice: Evacuate area. Remove containers from the path of fire if safe. Cool containers exposed to fire with plenty of water.
Personal Precautions: Evacuate, ventilate area. Remove ignition sources. Wear proper personal protective equipment, including gloves, goggles, and respirator.
Environmental Precautions: Prevent entry to drains, sewers, basements, or confined areas. Contain spill with earth or inert material.
Cleanup Methods: Absorb with inert material, then collect into containers for safe disposal. Wash spill area with water after cleanup is complete.
Handling: Use only in well-ventilated areas, away from sources of heat, sparks, or flame. Avoid shock, friction, and contamination with incompatible materials. Open containers cautiously.
Storage: Keep containers closed, stored in a cool, dry, well-ventilated place. Maintain temperature under specified limits, generally below 30°C. Isolate from combustible materials.
Separation: Keep away from strong acids, bases, reducing agents, and flammable substances.
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits.
Personal Protection: Chemical-resistant gloves, safety goggles, face shield, appropriate protective clothing. If ventilation is poor, use approved respirator.
Hygiene Measures: Wash hands thoroughly after handling. Do not eat, drink, or smoke during use.
Appearance: Colorless to pale yellow oily liquid
Melting Point: Approximately -20°C
Boiling Point: Decomposes explosively before boiling
Flash Point: Not applicable; substance decomposes
Solubility: Slightly soluble in water, more in organic solvents
Vapor Pressure: Low
Relative Density: Ranges from 1.0 to 1.1 g/mL (may vary)
Stability: Unstable under heat, shock, friction, or contamination. Organic peroxides are known for sensitivity to temperature and impact.
Reactivity: Vigorous reactions with reducing agents, strong acids, bases, and flammable materials.
Decomposition Products: Propanol, carbon dioxide, irritating or toxic fumes.
Conditions to Avoid: Heat, sunlight, open flames, and incompatible substances.
Acute Toxicity: Ingestion may cause nausea, vomiting, abdominal cramps, and headaches. Inhalation can lead to respiratory tract irritation and drowsiness.
Skin/Eye Effects: Causes moderate to severe irritation.
Long-Term Exposure: Prolonged contact may result in dermatitis or skin sensitization. No evidence of carcinogenicity under normal conditions of industrial handling.
Environmental Impact: Highly mobile in soil, potential to contaminate groundwater. Low persistence due to instability.
Aquatic Toxicity: Harmful to aquatic organisms if released in large quantities.
Biodegradability: Breaks down rapidly in the environment but may create toxic byproducts.
Waste Disposal: Collect and incinerate in a chemical incinerator equipped with afterburner and scrubber. Observe all federal, state, and local environmental regulations.
Container Disposal: Empty containers must be handled with care due to potential reactivity. Decontaminate before discard or recycling.
UN Number: 3106 (for organic peroxides, type D, liquid)
Hazard Class: 5.2 (Organic Peroxides)
Packaging Group: Not assigned; handled per regulations for organic peroxides
Special Transport Notes: Avoid heat, impact, and incompatible materials during transport. Follow rules for organic peroxides strictly.
OSHA Status: Classified hazardous under OSHA regulations.
EPA Status: Considered hazardous waste; subject to RCRA regulations.
Right-To-Know: Listed on chemical inventories in North America, Europe, and Asia with varying restrictions.
Workplace Labeling: Label containers clearly with chemical name, hazards, and emergency instructions.
