Isobutyl methacrylate Chemical Properties,Usage,Production

Chemical Properties

colourless liquid

Chemical Properties

Isobutyl methacrylate is a colorless and moderately flammable liquid.

Uses

Plastic industry: used in the manufacture of containing active hydroxyl acrylic resin. Coatings with epoxy resin, diisocyanate and melamine formaldehyde resin configuration used for preparing a two-component coating. In oil industry as additives for lubricating oil washing. In electronics industry used as electron microscope to take off the water. Textile industry used in the manufacture of adhesive fabric. Used as chemical reagents in analytical chemistry. In addition, also used for water immiscible embedding agent, used in the synthesis of medical polymer materials, thermosetting coatings and adhesives.

Uses

Monomer for acrylic resins.

Uses

Isobutyl methacrylate is primarily used as a monomer for acrylic resins .

Production Methods

Isobutyl methacrylate is produced by the esterification or transesterification of isobutyl alcohol with either methacrylic acid or methyl methacrylate .

General Description

Isobutyl methacrylate is a colorless liquid with a flash point of 120°F. When heated to high temperatures Isobutyl methacrylate may release acrid smoke and fumes. If Isobutyl methacrylate is subjected to heat for prolonged periods or becomes contaminated, Isobutyl methacrylate is subject to polymerization. If the polymerization takes place inside a container, the container may violently rupture. The vapors are heavier than air. Isobutyl methacrylate may be irritating to skin and eyes and produce a narcotic effect. Isobutyl methacrylate is used in making acrylic resins.

Air & Water Reactions

Flammable. Isobutyl methacrylate is sensitive to heat, air and light.

Reactivity Profile

Isobutyl methacrylate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Isobutyl methacrylate polymerizes readily.

Hazard

Moderate fire risk.

Health Hazard

May be harmful if inhaled; may cause dizziness or suffocation. Irritating to skin and eyes. Harmful if swallowed.
