Chemical Name: Allyl Methacrylate
CAS Number: 96-05-9
Concentration: Typically ranges from 98% to 100% in pure form
Impurities: Trace inhibitors such as hydroquinone monomethyl ether
Additives: Stabilizers may be present; check label or manufacturer information for any specific stabilizer content
Inhalation: Move to fresh air, keep at rest in a position comfortable for breathing, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water for at least 15 minutes, get medical help for irritation or allergic reaction
Eye Contact: Rinse cautiously with water for at least 15 minutes, remove contact lenses if present, get medical attention
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical care
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide
Unsuitable Extinguishing Media: Water jet may spread fire
Hazards from Combustion: Vapors can form explosive mixtures with air, combustion produces carbon oxides and unhealthy smoke
Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Firefighting Advice: Cool tanks and containers exposed to fire with water spray, avoid inhaling fumes
Personal Protection: Put on chemical-resistant gloves, goggles, and suitable protective clothing, ventilate area
Environmental Precautions: Prevent entry into waterways, drains, basements, and confined areas
Cleanup Methods: Absorb spill with inert material (sand, earth), transfer to chemical waste container, clean with detergent and water
Disposal: Follow safe disposal in accordance with local environmental regulations and company procedures
Handling: Keep containers tightly closed, ground and bond all equipment, avoid sources of ignition, use in well-ventilated spaces, avoid skin and eye contact
Storage: Store in cool, dry, well-ventilated area away from sunlight, heat, sparks, and open flames, keep away from oxidizers, acids, and bases, maintain inhibitor presence to reduce polymerization risks
Engineering Controls: Local exhaust ventilation, safety showers, eye wash stations
Exposure Limits: Workplace standards vary, some recommend TLV: 1 ppm (work area monitoring advised)
Personal Protective Equipment: Chemical-resistant gloves, splash goggles, flame-retardant protective clothing, respirators in case of poor ventilation or respirable mist
Hygiene Measures: Avoid inhaling vapors, wash hands after handling, change contaminated clothing
Appearance: Colorless to slightly yellow liquid
Odor: Pungent, sweet, acrid
Odor Threshold: Information limited, pungency usually noted at low ppm
pH: Not applicable
Melting Point: -80 °C
Boiling Point: 140–142 °C
Flash Point: 34 °C (93 °F)
Evaporation Rate: Moderate, similar to other acrylates
Flammability: Flammable liquid
Vapor Pressure: 3.6 mmHg at 20 °C
Solubility: Slightly soluble in water, mixes with many organic solvents
Specific Gravity (d20/20): 0.93
Partition Coefficient: log Pow ~1.6
Chemical Stability: Stabilized with inhibitor, polymerization possible if inhibitor is depleted or under high temperatures
Reactivity: Reacts with strong oxidizers, acids, bases, and free radical initiators
Hazardous Reactions: Exothermic polymerization releasing heat and vapors, risk higher without effective stabilizers
Conditions to Avoid: Heat, ignition sources, sunlight, pressure extremes, incompatible materials
Decomposition Products: Methacrylic acid, carbon oxides, other acrid compounds
Acute Toxicity: LD50 (oral, rat) 1020 mg/kg, LD50 (dermal, rabbit) higher than 1500 mg/kg
Skin Contact: Causes moderate irritation, possible sensitization or allergic response
Eye Contact: Serious irritation, pain, redness
Inhalation: Possible respiratory tract irritation, headaches, nausea
Chronic Effects: Repeated exposure may cause dermatitis, allergic skin reactions
Other Information: Not classified as carcinogen, mutagenic, or reproductive toxin by main regulatory agencies
Ecotoxicity: Harmful to aquatic life with long lasting effects, LC50 (zebra fish, 96h): 34 mg/L
Mobility: Moderate in soil, readily evaporates when released
Persistence and Degradability: Expected to degrade in natural settings but can linger if released in quantity
Bioaccumulation Potential: Low to moderate based on partition coefficient
Other Information: Avoid discharge to environment, always keep spill prevention in mind during use and cleanup
Waste Treatment Methods: Incinerate in licensed facility; never pour down the sewer or discard with household trash
Contaminated Packaging: Rinse empty containers thoroughly, observe label warnings and dispose via regulated methods
Other Suggestions: Use local waste contractors familiar with chemical waste for removal and neutralization
