Chemical Name: Diisobutyl Ether Synonyms: 2-Isobutoxy-2-methylpropane Chemical Formula: C8H18O CAS Number: 2050-43-3 Appearance: Clear, colorless, volatile liquid with a slightly sweet odor
Flammability: High, easily ignites around sparks or open flames Acute Health Risks: Irritates eyes and skin, inhalation can lead to dizziness or nausea Chronic Health Risks: Long-term exposure carries risks to the central nervous system Environmental Risks: Harmful to aquatic environments, doesn’t break down quickly Pictograms: Flame for flammable liquid, exclamation point for irritant
Main Ingredient: Diisobutyl Ether, usually above 99% purity Impurities: Possible traces of alcohols or peroxides from storage or during synthesis Additives: Stabilizers not always used, but peroxide levels should be tracked for safety
Inhalation: Remove to fresh air, keep calm and upright Skin Contact: Wash immediately with soap and plenty of water Eye Contact: Rinse gently with water for several minutes, avoid rubbing Swallowing: Don’t induce vomiting, rinse mouth, get medical help right away
Suitable Extinguishing Media: Use foam, dry chemicals, or CO2 Unsuitable Media: Avoid using water jets that spread the fire Special Hazards: Vapors can travel, forming explosive mixtures with air Protective Equipment: Full protective gear and self-contained breathing apparatus Special Precautions: Cool containers exposed to fire with water spray, do not walk through spilled material
Personal Precautions: Remove sources of ignition, use spark-resistant tools Protective Equipment: Wear gloves, protective goggles, and respirators Containment: Absorb with non-combustible material, such as sand or earth Clean-up: Collect and transfer to sealed containers, ventilate the area well Environmental Precautions: Prevent run-off into storm drains and waterways
Handling: Ground and bond containers during transfers, avoid breathing vapors Storage: Keep in cool, dry, and well-ventilated spots, away from sunlight and incompatible substances like oxidizers Containers: Use tightly sealed metal or glass, monitor regularly for any evidence of peroxides forming during storage Other Tips: Put clear labeling on all containers, enforce “no smoking” rules, separate from acids and strong bases
Permissible Exposure Limit: Limit exposure based on established occupational safety standards, though no specific OSHA PELs exist for all ethers Engineering Controls: Local exhaust ventilation and closed systems work better than open handling Personal Protective Equipment: Chemical-resistant gloves, splash-proof goggles, lab coats, and in some cases, vapor respirators Hygiene: Wash thoroughly before eating or drinking, store clean work clothes separately from personal ones
Boiling Point: About 108°C Melting Point: Below -90°C Vapor Pressure: Moderate, adding to its volatility Density: Lighter than water, floats on its surface Odor: Sweet and slightly fruity, not always easy to detect at dangerous levels Solubility: Insoluble in water, mixes with most organic solvents Flash Point: Between 10–20°C, so ordinary room conditions already push it close to fire hazards Explosive Limits: Broad range, raising risks in poorly ventilated areas
Chemical Stability: Stable under regular handling but unstable when exposed to air and light over longer periods Reactivity: Reacts with strong oxidizers and acids Hazardous Decomposition: Produces toxic gases during combustion Polymerization: Doesn’t polymerize, but can form explosive peroxides unless inhibitors are added
Acutely Toxic Routes: Inhalation, skin, eyes, ingestion Symptoms: Shortness of breath, headache, eye redness, dizziness, loss of coordination Sensitization: Not commonly associated with skin or respiratory allergy Carcinogenicity: Not classified as human carcinogen by IARC or other major agencies Mutagenicity / Reproductive Hazards: No strong evidence, but reliable studies are limited
Aquatic Toxicity: May be harmful to fish and other aquatic life due to poor solubility but high persistence Persistence and Degradability: Breaks down slowly, can linger in cool waters Bioaccumulation: Low, but repeated spills concentrate risks Other Concerns: Volatile organic compound, contributes to smog and ozone formation
Waste Disposal: Burn in permitted chemical incinerators when possible, otherwise, send waste to certified chemical disposal centers Container Disposal: Empty containers still hold vapor, vent fully, triple rinse before recycling Regulatory Rules: Follow regional guidelines, avoid pouring even tiny amounts down drains
UN Number: Classified as a flammable liquid for international transport Packing Group: II or III, depending on volume and packaging Labels: Clear flammable liquid warnings required during shipping Special Precautions: Vent containers properly in transit, never ship with incompatible materials
Major Laws: Included in U.S. EPA TSCA Chemical Inventory, EU REACH, and other main chemical inventories Workplace Limits: Regulated under Hazard Communication Standard Labeling Obligations: Must show flame symbol and “Danger” for rapid ignition Regional Restrictions: Some local health or fire codes limit storage volumes in cities, schools, and workplaces
