Chemical name: Cyclohexylisobutane
Common synonyms: No broadly established synonyms are widely used
Appearance: Clear or nearly colorless liquid, mild hydrocarbon odor
Recommended uses: Intermediate in specialty chemical syntheses and as a solvent for organic compounds
Classification: Flammable liquid, can cause skin and eye irritation, inhalation at high concentrations poses risk of central nervous system depression
Label warnings: Flammable, keep away from open flames and sparks, avoid breathing vapors or mist, avoid direct contact with skin and eyes
Critical symptoms: Drowsiness, dizziness, headache, possible nausea, and respiratory difficulty in high concentrations
Symptoms of exposure: Redness, itching, dryness with skin contact; eye watering, burning with eye contact; dizziness, lightheadedness, and headaches after inhaling high concentrations
Main ingredient: Cyclohexylisobutane (CAS Number unavailable in public regulatory sources)
Purity: Generally available as high-purity substance, but trace mixed hydrocarbons may be present from synthesis
Additives: Most formulations carry no significant stabilizers, preservatives, or dyes
Inhalation: Move to fresh air, provide oxygen if needed, monitor for continued symptoms, seek medical attention for difficulty breathing or prolonged symptoms
Skin contact: Remove contaminated clothing immediately, wash exposed skin thoroughly with plenty of water and mild soap, watch for redness or irritation
Eye contact: Rinse immediately with large amounts of clean water, keep eyes open and moving, seek medical attention for lingering pain or visual changes
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical care if large amounts are swallowed or if symptoms like nausea or drowsiness appear
Suitable extinguishing media: Use foam, dry chemical, or carbon dioxide for small fires; water spray for cooling containers but not for extinguishing spills
Hazards on burning: Produces dense smoke and potentially irritating or toxic fumes, including carbon monoxide and carbon dioxide
Special protective equipment: Firefighters should wear self-contained breathing apparatus and full protective gear; avoid inhaling smoke vapors
Fire behavior: Vapors can travel along surfaces to distant ignition sources, flashback possible
Personal precautions: Evacuate unnecessary personnel, ventilate area, eliminate all ignition sources, wear protective gloves and goggles, ventilate area
Spill response: Stop leak if safe, contain spill with inert materials like sand, collect and transfer using non-sparking tools into sealed, properly labeled containers
Environmental precautions: Prevent runoff into drains, surface water, or soil; vapor may affect responders
Handling: Work only in well-ventilated spaces or use local exhaust ventilation, ground and bond containers during liquid transfer, use spark-proof tools
Hygiene measures: Always wash hands after handling, remove contaminated clothing before leaving work area, avoid eating, drinking, or smoking in work zones
Storage conditions: Store in tightly closed containers in a cool, well-ventilated area, away from heat sources, open flames, oxidizing agents, and strong acids
Bulk storage: Larger volumes should be stored with appropriate spill containment and vapor recovery systems
Engineering controls: Local exhaust ventilation in areas of vapor generation, regular environmental vapor monitoring
Eye protection: Chemical safety goggles or face shield
Skin protection: Wear impervious gloves and aprons to prevent skin contact
Respiratory protection: Use air-purifying respirators with organic vapor cartridges in poorly ventilated areas or where vapor concentrations exceed recommended limits
Occupational exposure limits: Established limits for cyclohexylisobutane do not appear in major regulatory listings; analogous straight-chain and branched hydrocarbons have low limits (such as 100-300 ppm for similar substances)
Physical state: Liquid at room temperature
Appearance: Clear to faintly yellow
Odor: Mild hydrocarbon
Boiling point: Estimated above 130°C based on structure and related substances
Vapor pressure: Moderate; higher than water, indicating potential for evaporative loss
Solubility: Insoluble in water, miscible with other hydrocarbons
Flash point: Near or above 40°C (estimated), making it a Class II flammable liquid under some regulations
Density: Near or slightly below 1.0 g/cm³
Chemical stability: Stable under normal handling and storage conditions
Conditions to avoid: Open flames, high heat, strong oxidizers, sources of static electricity
Incompatible materials: Strong acids, oxidizing agents like chlorine and permanganates
Hazardous reactions: None expected under ordinary use; hazardous decomposition byproducts possible under fire
Acute effects: Inhalation can cause dizziness, nausea, and headache; skin and eye exposure may result in mild to moderate irritation
Chronic effects: Extended, repeated exposure may dry or crack the skin; organic solvent abuse history points to risk of nervous system effects, though there is no strong evidence for carcinogenicity in related cycloalkanes or branched alkanes
Sensitization: Not known to be a major sensitizer
Other health impacts: Not well-documented, but workers in chemical industries observe hydrocarbons with similar structures cause headaches, fatigue, and rare cases of dizziness in poorly ventilated areas
Aquatic effects: Poorly soluble in water, tends to float and spread in thin films; can threaten aquatic life with physical coating
Environmental persistence: Like many hydrocarbons, tends to break down slowly in nature; high persistence in soils and water systems without active remediation
Bioaccumulation: Potential for moderate accumulation in aquatic organisms, usual with non-polar organic chemicals
Air impact: Volatile, can contribute to urban photochemical smog through atmospheric reactions
Waste handling: Treat as hazardous organic waste, incinerate in accordance with local environmental regulations
Avoid: Direct disposal into drains, surface waters, or natural environment
Recycling: Feasible where hydrocarbon recycling infrastructure exists, otherwise destruction recommended
Empty containers: May retain residue and vapor, treat as hazardous, do not reuse for food or water
Shipping class: Typically shipped as a flammable liquid; transport under properly labeled, sealed drums or containers
Precautions: Insure containers are tightly closed and upright; segregate from oxidizers in transit
Accident response: Emergency responders should reference placards for flammable liquids and use vapor suppression foam if required
Workplace requirements: Exposure and hazard controls align with standard guidance for flammable aliphatic hydrocarbons; chemical hygiene plans, hazard communication, and fire code compliance are necessary
Labeling: Flammable, keep closed, handle with protection, toxicological and ecological risks must be communicated to workers
Waste management: Federal and local regulations mandate controls on liquid waste disposal, emissions, and accidental releases
Community right-to-know: In jurisdictions with community notification laws, may fall under hazardous chemical inventory disclosure
