Butyl methacrylate CAS NO (97-88-1) Available In Bulk Quantity

Butyl Methacrylate (97-88-1)

1. Chemical Identity: Butyl methacrylate is a chemical compound with the molecular formula C8H14O2 and the CAS number 97-88-1. It belongs to the class of methacrylate esters and is characterized by its methacrylate functional group, which consists of a methacrylic acid moiety attached to a butyl alcohol residue.

2. Structure and Properties: Butyl methacrylate features a linear alkyl chain comprising four carbon atoms (butyl group) attached to the alpha carbon of the methacrylate moiety. It exists as a colorless liquid with a characteristic odor and is soluble in organic solvents such as acetone, ethanol, and toluene.

3. Synthesis: Butyl methacrylate is typically synthesized through the esterification reaction between methacrylic acid and butanol in the presence of an acid catalyst. This reaction results in the formation of butyl methacrylate and water, which is subsequently removed to drive the reaction towards completion.

4. Applications: Butyl methacrylate is widely used as a monomer in the production of various polymers and copolymers, particularly in the manufacture of acrylic resins and coatings. It imparts desirable properties such as flexibility, adhesion, and weather resistance to the final polymer products.

5. Polymerization: Butyl methacrylate undergoes free radical polymerization to form polymers with a wide range of molecular weights and structures. It can be homopolymerized to produce polybutyl methacrylate or copolymerized with other monomers such as methyl methacrylate to tailor the properties of the resulting polymer.

6. Coatings and Adhesives: Due to its excellent film-forming properties and adhesion to various substrates, butyl methacrylate is commonly used in the formulation of coatings, adhesives, and sealants for applications in automotive, architectural, and industrial coatings, as well as inks and adhesives.

7. Medical and Dental Applications: Butyl methacrylate-based polymers are utilized in medical and dental applications, including dental restorative materials, orthopedic implants, and drug delivery systems. These polymers offer biocompatibility, durability, and ease of processing, making them suitable for biomedical applications.

8. Safety Considerations: Butyl methacrylate is generally considered to have low acute toxicity, but exposure to its vapors or liquid form may cause irritation to the respiratory tract, skin, and eyes. Proper handling, storage, and personal protective equipment are recommended to minimize exposure risks.

9. Environmental Impact: Like other methacrylate esters, butyl methacrylate may pose environmental risks if released into the environment. Measures should be taken to prevent its release into water bodies or soil, and appropriate waste management practices should be followed to minimize environmental contamination.

10. Regulatory Compliance: Butyl methacrylate is subject to regulatory controls and may be classified as a hazardous substance in some jurisdictions. Compliance with occupational health and safety regulations, as well as environmental regulations, is essential for the safe handling, transportation, and disposal of butyl methacrylate and its derivatives.
