Name: Isobutyl Acrylate [Stabilized]
Chemical Formula: C7H12O2
CAS Number: 106-63-8
Appearance: Clear, colorless liquid with a distinct acrylate odor
Common Use: Polymer manufacturing, adhesives, coatings, inks
Main Risks: Flammability, skin and eye irritation, inhalation hazard
GHS Classification: Flammable liquid, category 2; skin irritant, category 2; eye irritant, category 2A
Signal Word: Danger
Hazard Statements: Highly flammable liquid and vapor; causes skin and eye irritation
Pictograms: Flame and exclamation mark required on containers
Potential Exposures: Inhalation during mixing, skin contact while handling, spills releasing vapor in closed spaces
Isobutyl Acrylate: ≥99%
Stabilizer (e.g., hydroquinone or MEHQ): typically <0.1%
Impurities: Trace levels, specifics depend on manufacturer
Inhalation: Remove to fresh air, monitor for breathing difficulties, seek medical attention if symptoms persist
Skin Contact: Rinse with plenty of water for at least 15 minutes, remove contaminated clothing
Eye Contact: Irrigate eyes with water for several minutes, avoid rubbing, consult a doctor if irritation develops
Ingestion: Rinse mouth, avoid inducing vomiting, seek immediate medical advice
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide
Unsuitable Media: Direct water stream can spread burning liquid
Special Hazards: Flammable vapors may travel to ignition source, combustion produces acrid smoke, carbon monoxide, and carbon dioxide
Protective Equipment: Full protective clothing, self-contained breathing apparatus for responders
Personal Precautions: Avoid breathing vapors, use non-sparking tools, ventilate area
Environmental Precautions: Prevent entry into drains, waterways, soil
Cleanup Methods: Contain spill with inert absorbent, collect in suitable labeled containers, dispose according to regulations
Handling: Work in well-ventilated spaces, minimize static discharge, keep away from ignition sources, ground all equipment
Storage: Store in tightly closed containers, cool and dry area, away from heat, sparks, and sunlight
Incompatible Materials: Strong oxidizers, acids, and bases accelerate decomposition or cause violent reactions
Engineering Controls: Local exhaust ventilation, vapor-proof fittings
Personal Protective Equipment: Nitrile gloves, goggles, flame-resistant clothing, organic vapor respirators
Exposure Limits: No OSHA PEL or ACGIH TLV assigned, but minimizing vapor and skin contact reduces risk
Appearance: Clear, mobile liquid
Odor: Pungent, acrylate-like
Boiling Point: 155°C
Melting Point: -64°C
Flash Point: 41°C (closed cup)
Vapor Pressure: 2.8 mmHg at 20°C
Solubility: Slightly soluble in water, readily mixes with organic solvents
Density: 0.884 g/cm³ at 20°C
Chemical Stability: Stable under recommended storage, sensitive to heat and light without stabilizers
Conditions to Avoid: Heat, flames, sources of ignition, strong acids or bases
Hazardous Decomposition: Acrid smoke, carbon monoxide, carbon dioxide form during fire or extreme heat
Polymerization Risk: May undergo uncontrolled exothermic polymerization if heated or contaminated, especially without stabilizer present
Health Effects: Skin exposure causes redness, burning, and sometimes allergic reactions; inhalation may trigger respiratory irritation or drowsiness
Acutely Toxic Doses: Oral LD50 (rat) reported near 11,200 mg/kg
Sensitization: Prolonged or repeated contact can lead to skin sensitization in some people
Long-term Exposure: May affect liver, kidney, or nervous system based on animal studies
Aquatic Toxicity: Harmful to fish and aquatic organisms in high concentrations
Persistence: Moderately persistent in water or soils, prone to slow degradation by sunlight and microorganisms
Bioaccumulation: Low potential for accumulation in living organisms
Disposal Method: Collect wastes in labeled containers, send to licensed chemical disposal facility
Incineration: Suitable for complete destruction if permitted by local regulations
Avoid: Direct release into waterways, landfills without treatment, or open drains
UN Number: 2218 (for Isobutyl Acrylate)
Hazard Class: 3 (flammable liquid)
Packing Group: III
Proper Shipping Name: Isobutyl Acrylate, stabilized
Transport Precautions: Keep containers upright, protect from physical damage and heat, proper hazard symbols on all shipments
Labelling: Required hazard pictograms and statements under GHS and local regulations
VOC Regulation: Subject to regional volatile organic compound limits
Reportable Quantity: Some regions require spills above set limits to be reported to authorities
Safety Compliance: Monitoring shelf life, keeping up with changing chemical bans or exposure limits keeps workplaces safer and in line with global standards
