Butyl methacrylate Chemical Properties,Uses,Production
Description
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.
Uses
n-Butyl methacrylate is used as a monomer for resins, solvent coatings, adhesives, oil additives, emulsions for textiles, leather, and paper finishing and in the manufacture of contact lenses . It is also used in dental resins, oil dispersible pesticides, and acrylic surface coatings and as copolymers, for example, in paraffin embedding media .
Production Methods
n-Butyl methacrylate is produced by the reaction of methacrylic acid or methyl methacrylate with butanol .
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.
Air & Water Reactions
Flammable. Sensitive to moisture. Insoluble in water.
Reactivity Profile
Butyl methacrylate 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 .
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.
Fire Hazard
Behavior in Fire: Containers may explode due to polymerization.
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.
Safety Profile
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.
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.
Shipping
UN2227 Butyl methacrylate, stabilized, Hazard Class: 3; Labels: 3—Flammable liquid.
Purification Methods
Purify as for butyl acrylate. [Beilstein 2 IV 1525.]
Incompatibilities
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
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.
