Moderately toxic by
intraperitoneal route. Mddly toxic by
ingestion, inhalation, and skin contact. An
experimental teratogen. Experimental
reproductive effects. A skin irritant.
Flammable liquid when exposed to heat or
flame. Explosive in the form of vapor when exposed to heat or flame. Violent
polymerization can be caused by heat,
moisture, oxidizers. To fight fire, use foam,
dry chemical, CO2. When heated to
decomposition it emits acrid smoke and
irritating fumes. | [Hazardous Substances Data]

| Hazard Information | Back Directory | [General Description]
A clear colorless liquid. Flash point 130°F. Less dense (7.5 lb/gal) than water and insoluble in water. Hence floats on water. Vapors heavier than air. Used to make resins adhesives, and oil additives. | [Reactivity Profile]
N-BUTYL METHACRYLATE(97-88-1) reacts exothermically with acids. Reacts with oxidizing agents. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat is generated with caustic solutions. Generates flammable hydrogen with alkali metals and hydrides. Polymerizes easily . | [Air & Water Reactions]
Flammable. Sensitive to moisture. Insoluble in water. | [Hazard]
Toxic by ingestion. Moderate fire risk.
| [Health Hazard]
Inhalation may cause nausea because of offensive odor. Contact with liquid causes irritation of eyes and mild irritation of skin. Ingestion causes irritation of mouth and stomach. | [Potential Exposure]
Forms an explosive mixture with air.
Unless inhibitor is maintained at the proper level, oxidizers,
heat, ultraviolet light, contamination, or moisture may
cause polymerization. May accumulate static electrical
charges and cause ignition of its vapors. | [Fire Hazard]
Behavior in Fire: Containers may explode due to polymerization. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, gemedical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Medical observation is recommended for 24 to 48 hours
after breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug or
other inhalation therapy | [Shipping]

Forms an explosive mixture with air.
Unless inhibitor is maintained at the proper level, oxidizers,
heat, ultraviolet light, contamination, or moisture may

Butyl methacrylate (BMA) is the organic compound with the formula C4H9O2CC(CH3)=CH2. A colorless liquid, it is a common monomer for the preparation of methacrylate polymers. It is typically polymerized under free-radical conditions.
Butyl methacrylate is a versatile, plasticizing methacrylate monomer that acts as an important building block in many copolymer compositions. Serving as a base for acrylic resins, BMA provides exceptional weather resistance, high gloss, color retention, and durability. BMA contributes more intermediate glass transition and hardness values, with a glass transition temperature (Tg) of 20 °C. | [Chemical Properties]
Butyl methacrylate is a flammable, colorless
liquid with a mild odor. | [Chemical Properties]
clear colourless liquid with an ester-like odour | [Waste Disposal]
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed. | [Definition]
ChEBI: Butylmethacrylate is an enoate ester. | [Production Methods]
n-Butyl methacrylate is produced by the reaction of
methacrylic acid or methyl methacrylate with butanol . | [Chemical Reactivity]
Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: May occur upon exposure to heat; Inhibitor of Polymerization: 9-15 ppm monomethyl ether of hydroquinone; 90-120 ppm hydroquinone. | [storage]
Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Protect against physical damage. Before entering confinedspace where this chemical may be present, check to makesure that an explosive concentration does not exist. Outsideor detached storage is preferred. Prior to working with butylmethacrylate you should be trained on its proper handlingand storage. Store in tightly closed containers in a cool,well-ventilated area away from incompatible materialslisted above and from light and heat. Butyl methacrylateshould be kept refrigerated and inhibited with 10-ppmhydroquinone monomethylether. Metal containers involvingthe transfer of this chemical should be grounded andbonded. Drums must be equipped with self-closing valves,pressure vacuum bungs, and flame arresters. Use only nonsparking tools and equipment, especially when opening andclosing containers of this chemical. Sources of ignition,such as smoking and open flames, are prohibited where thischemical is used, handled, or stored in a manner that couldcreate a potential fire or explosion hazard. | [Purification Methods]
Purify as for butyl acrylate. [Beilstein 2 IV 1525.] |
