Other Names: 1-methylpropyl acetate
Common Uses: solvent in paints, coatings, thinners
Odor: fruity, sweet
Appearance: colorless liquid
Classification: flammable liquid, eye and respiratory irritant
Hazard Statements: vapor may cause drowsiness, headaches, or dizziness, repeated exposure can dry out skin, inhaling high concentrations poses central nervous system effects
Label Symbols: flammable, exclamation mark
Routes of Exposure: inhalation, skin contact, eye contact
Acute Risks: irritation, nausea, central nervous system depression
Chronic Risks: potential liver or kidney effects from prolonged or repeated exposure
Main Ingredient: sec-butyl acetate (>99%)
Impurities: trace acetates, moisture
Physical Form: liquid
Eye Contact: flush with water several minutes, seek medical help for redness or pain
Skin Contact: wash with soap and water, remove contaminated clothes
Inhalation: move person to fresh air, support breathing as needed, call for medical help if symptoms linger
Ingestion: rinse mouth, never induce vomiting, seek prompt medical advice
Suitable Extinguishing Agents: foam, dry chemical, carbon dioxide
Specific Hazards: vapor can form explosive mix with air, dense vapors may travel to ignition sources
Precautions: firefighters should wear self-contained breathing apparatus
Decomposition Products: may release carbon monoxide and carbon dioxide
Personal Protection: wear suitable gloves, goggles, and mask
Spill Response: ventilate area, eliminate ignition sources, contain with inert matter
Cleaning Up: absorb with sand or vermiculite, collect in clear containers, dispose according to rules
Environmental Protection: avoid discharging into drains, surface water, or soil
Handling: use only in ventilated spaces, ground containers, avoid inhaling vapors
Storage: keep away from heat, sparks, flame, store in tightly sealed, approved containers, keep out of the sun
Compatibility: keep separate from strong acids, alkalis, and oxidizers
Occupational Exposure Limits: workplace limits exist based on local regulations
Engineering Controls: use fume hoods or local exhaust to keep vapor levels low
Personal Protection: use nitrile gloves, safety goggles, flame-resistant clothing, use approved respirator under high vapor
Hygiene Measures: wash hands before breaks, do not eat or drink while handling
Boiling Point: about 112°C
Flash Point: 23–27°C (closed cup)
Density: roughly 0.87 g/cm³
Vapor Pressure: moderate at room temperature
Solubility: insoluble in water, miscible with most organic solvents
Evaporation Rate: moderate to fast
Color: clear
Odor Threshold: detectable at low concentrations
Reactivity: reacts with strong oxidizers
Chemical Stability: stable under recommended storage and handling
Hazardous Reactions: generates flammable mixtures with air easily
Decomposition: can produce toxic fumes in fire (carbon monoxide, carbon dioxide)
Conditions to Avoid: heat, sparks, open flames; contact with incompatible chemicals
Likely Routes of Exposure: lungs, skin, eyes
Acute Toxicity: oral LD50 in rats: ~13,000 mg/kg
Short-term Effects: drowsiness, dizziness, headaches, eye and skin irritation
Long-term Exposure: animal studies suggest slight effects on liver and kidneys at high, sustained doses
Sensitization: not recognized as a sensitizer
Environmental Fate: evaporates quickly, breaks down in air
Persistence: low, not likely to bioaccumulate
Aquatic Toxicity: can cause short-term harm to aquatic life
Soil Mobility: high, may leach into groundwater
Hazard to Plants/Animals: large spills can stress or kill local species
Preferred Method: treat as hazardous waste
