Chemical Name: 1,3-Diethylbenzene
Other Names: m-Diethylbenzene
Chemical Formula: C10H14
Physical Appearance: Colorless liquid, mild aromatic odor
Classification: Flammable liquid, harmful on inhalation or ingestion, irritant to skin and eyes
Hazard Statements: Easy to ignite under normal conditions, vapor can form explosive mixtures with air at room temperature, exposure brings risk of drowsiness, headache, and irritation
Risk Phrases: Harmful by inhalation and ingestion, irritating to eyes and skin, risk of serious damage if contact is prolonged
Labeling Elements: Flame pictogram, exclamation mark to signal moderate hazard
Main Component: 1,3-Diethylbenzene (typically >99%)
Impurities: Often contains trace amounts of other diethylbenzene isomers; limited presence of heavier aromatic hydrocarbons if manufactured in bulk
Inhalation: Immediately move outside to fresh air, attempt deep steady breathing if dizziness or headache occur
Skin Contact: Remove contaminated clothing, wash with soap and water, seek medical attention for redness or persistent irritation
Eye Contact: Rinse with running water for several minutes, avoid rubbing, consult medical professionals if pain or vision changes stay
Ingestion: Rinse mouth, avoid inducing vomiting, get professional medical help, monitor for confusion or nausea
Suitable Extinguishers: Dry chemical powder, foam, carbon dioxide
Specific Hazards: Releases toxic fumes such as carbon monoxide, dense black smoke may fill small rooms rapidly
Protection for Firefighters: Wear self-contained breathing equipment, full protective clothing, stay upwind from fire site, avoid inhaling fumes
Personal Precautions: Evacuate area if possible, ventilate space, put on chemical-resistant gloves, goggles, and respirator
Methods for Cleaning Up: Contain liquid using sand, earth, or inert absorbent, prevent from reaching drains, use spark-proof tools and containers to collect spills, dispose of waste in accordance with regulatory norms, ventilate space thoroughly before re-entry
Handling: Only handle in well-ventilated places, avoid breathing vapors, wash hands after direct contact every time
Storage: Store away from heat, flames, or oxidizing substances, use tightly closed containers, keep in cool, dry locations, separate from incompatible chemicals like acids or oxidizers, don’t mix with lab waste streams that may react
Engineering Controls: Install local exhaust ventilation or fume hoods, monitor air concentrations regularly
Personal Protection: Chemical splash goggles, nitrile or other solvent-resistant gloves, long sleeves, flame-resistant apron for high exposure risk, approved organic vapor respirators if there’s a risk of inhaling high concentrations
Boiling Point: Close to 180°C
Melting Point: Falls around -45°C
Vapor Pressure: Moderate; evaporates faster at higher temperatures
Solubility: Barely dissolves in water, mixes well with organic solvents
Appearance: Clear to slightly yellowish oily liquid, faintly sweet aromatic odor
Chemical Stability: Remains stable under normal usage, breaks down quickly under strong heat or light
Reactivity: Easily reacts with oxidizing agents, acids, some metals
Conditions to Avoid: Contact with spark sources, open flames, direct sunlight, storage alongside strong acids or peroxides
Decomposition Products: Burns to release toxic gases including benzene-like compounds, carbon oxides
Inhalation Effects: Headache, dizziness, nausea at moderate vapor concentrations, high exposures can impair consciousness
Skin/ Eye Effects: Irritation, redness, swelling for prolonged contact or splashes
Chronic Toxicity: No clear evidence of carcinogenicity, repeated exposure may irritate respiratory tract
Acute Effects: Central nervous system suppression, signs of confusion, lethargy
Long-Term Data: Animal studies show low risk at typical exposures, but solvent abuse cases link similar compounds to liver and kidney damage
Mobility: Slow movement in soil, likely to evaporate if spilled on open ground
Degradation: Gradual breakdown by natural bacteria over weeks
Aquatic Toxicity: High concentrations threaten fish and aquatic insects, low solubility reduces immediate risk but long-term accumulation poses a problem
Persistence: Trace residues linger in ground water for months
Bioaccumulation: Potential for building up in animal tissue isn’t well studied; caution should guide decisions about large spills or releases near water
Safe Disposal: Use hazardous waste collection facilities, never mix with regular garbage, avoid pouring down drains
Incineration: High-temperature facilities with scrubbers remove risk of fumes
Recycling: Limited prospects for reclaiming or purifying due to contamination risks
Transport Classification: Classified as flammable liquid, relevant for road, ship, and rail
Packing Group: Usually group III for moderate hazard; ensure leak-proof drums or tankers
Precautionary Measures: Containers must be kept upright, labeled in line with flammable liquid standards, emergency kit for absorption and fire suppression should travel with major shipments
Compliance: Subject to chemical safety legislation in most regions, flagged as flammable substance, employers use workplace exposure limits recommended by health and labor authorities
Handling Restrictions: Only trained staff should handle bulk volumes, reporting mandatory for significant spills or releases
Signal Words and Pictograms: Clear hazard markings required on drums, vehicles, and storage rooms
