What Is Methyl Methacrylate?
Methyl methacrylate is a colorless, flammable liquid with a strong, sharp odor. It is primarily used as a monomer to produce polymethyl methacrylate (PMMA), commonly known as acrylic or acrylic glass. The properties of methyl methacrylate, such as transparency, weather resistance, and lightweight nature, are highly valued in various industrial applications. Chemically, it belongs to the methacrylate family and is classified as an ester of methacrylic acid.
Derived mainly from acetone, hydrogen cyanide, and methanol, methyl methacrylate is produced via two major industrial processes: the acetone cyanohydrin (ACH) process and the newer ethylene-based process. These production techniques affect the properties of methyl methacrylate, such as environmental impact, energy efficiency, and raw material requirements.
