Chemical Name: Dipropyl Ether
Concentration: > 99% by weight
Impurities: Trace peroxides (can form on storage), water (<0.5%)
EC Index Number: 603-040-00-6
Other Identifiers: No significant stabilizers or additives under standard supply conditions
Inhalation: Remove to fresh air. Support breathing if breathing stops. Seek medical attention for symptoms—headache, dizziness, respiratory irritation.
Skin Contact: Remove contaminated clothing. Flush skin with plenty of water and soap. Monitor for persistent redness or irritation. Seek medical advice if symptoms develop.
Eye Contact: Rinse carefully with water for 15 minutes, keeping eyelids open. Remove contact lenses if present and easy to do. See a healthcare professional.
Ingestion: Do not induce vomiting. Rinse mouth. Keep affected individual calm and get immediate medical help. Risk of chemical pneumonitis if aspirated.
General Advice: Provide medical personnel with product label or MSDS details for proper care.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide. Water spray may be used for cooling containers but not for putting out flames directly.
Unsuitable Media: Direct water jet—risks spreading fire
Hazards Specific to Product: Vapors heavier than air, risk of flashback. Forms explosive mixtures with air at room temperature. In heat, may form peroxides which can detonate.
Protective Equipment For Firefighters: Self-contained breathing apparatus, full protective suit. Avoid inhalation of combustion products.
Decomposition Products: Carbon monoxide, carbon dioxide, various hydrocarbons
Personal Precautions: Evacuate area, ventilate affected space. Remove all ignition sources. Avoid inhaling vapors—wear self-contained breathing apparatus if necessary. Prevent skin or eye contact by using proper PPE.
Environmental Precautions: Prevent entry into drains, water courses, soil. Notify authorities if spill occurs on soil or in water systems.
Containment: Use non-sparking tools. Dike to prevent spread. For small spills, absorb with sand or inert material. Large spills—use foam to suppress vapors.
Cleanup: Collect waste in suitable, labeled, tightly sealed containers. Dispose of according to regulations. Clean contaminated area with detergent and water.
Handling: Work with adequate local exhaust and away from heat, sparks, open flame. Ground containers and transfer vessels to avoid static discharge. Handle only in locations with proper fire control equipment. Avoid breathing vapor; don’t eat, drink, or smoke near product use.
Storage: Keep tightly closed in approved flammable liquid containers. Store away from oxidizers, acids, bases, and sunlight. Maintain in a cool (<25°C), dry, well-ventilated place. Check dated stock, rotate inventory frequently, and monitor for peroxide formation. Add stabilizers if long-term storage is needed.
Incompatibilities: Strong acids, oxidizers, alkali metals. Heat and light can speed up peroxide growth.
Occupational Exposure Limits: OSHA TWA (none established), ACGIH TLV: 100 ppm (recommended)
Engineering Controls: Use fume hood or explosion-proof mechanical ventilation.
Eye Protection: Chemical safety goggles and face shield.
Skin Protection: Nitrile or butyl rubber gloves; flame-resistant clothing.
Respiratory Protection: Use NIOSH-approved organic vapor cartridge respirators if ventilation is inadequate.
Hygiene Measures: Wash hands, forearms, and face after handling. Remove and wash contaminated clothing before reuse.

Explosion Limits: 1.1% (lower), 6.9% (upper) in air
Vapor Pressure: 125 mmHg at 20 °C
Vapor Density (air = 1): 3.5
pH: Not applicable
Partition Coefficient (n-octanol/water): 2.2 (estimated)
Solubility: Slightly soluble in water; miscible with alcohol, ether, chloroform
Density: 0.724 g/cm3 at 20 °C

Evaporation Rate: Rapid (compared to butyl acetate)
Chemical Stability: Stable under recommended storage. Forms explosive peroxides over time, especially on exposure to air, heat, or sunlight.
Reactivity: Reacts strongly with oxidizing agents, acids, alkali metals.
Hazardous Reactions: Peroxides can shock, ignite, or detonate if concentrated. Mixtures with air highly flammable.
Decomposition Products: Carbon oxides, flammable gases
Conditions to Avoid: Heat, spark, flame, sunlight, storage with incompatible chemicals.
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: Inhalation of high vapor concentrations can cause central nervous system depression—headache, dizziness, drowsiness, confusion, motor incoordination, and in severe exposures, unconsciousness.
Oral LD50 (rat): 930 mg/kg
Inhalation LC50 (rat, 4 hr): Not precisely determined (>5000 ppm likely non-lethal)
Skin Irritation: Mild irritant
Eye Irritation: Causes severe irritation, possible temporary damage if not promptly rinsed
Chronic Effects: Repeated exposure can harm liver, kidneys, and cause dermatitis.
Carcinogenicity: No known human carcinogenic potential; not listed by IARC, NTP, or OSHA.
Mutagenicity, Reproductive Toxicity: No clear evidence in animal studies
Aquatic Toxicity: Low to moderate toxicity for fish and aquatic invertebrates. Minimal biodegradability in oxygen-poor water.
Persistence and Degradability: Tends to evaporate quickly from surfaces; can persist if spilled in soil or subsurface water where oxygen is absent.
Bioaccumulation: Low potential for bioaccumulation due to volatility.
Mobility in Soil: Likely to leach rapidly; may contaminate groundwater.
Other Effects: Ether odor can discourage wildlife from contaminated areas.
Waste Treatment Methods: Dispose of as hazardous chemical waste. Incineration recommended at licensed facility with proper scrubbing of exhaust gases.
Packaging Disposal: Rinse thoroughly, offer for reconditioning or proper disposal at approved site.
Special Precautions: Prevent peroxide formation during waste storage—treat with appropriate reducing agents before disposal if needed.
Legal Requirements: Must comply with local, regional, and national hazardous waste regulations. Never pour down drain or release into the environment.
