How is methyl methacrylate manufactured?

1. What is the main raw material used in the production of methyl methacrylate?

The main raw material used in the production of methyl methacrylate is acetone and hydrogen cyanide.

2. Describe the process of manufacturing methyl methacrylate.

Methyl methacrylate is primarily manufactured through the acetone cyanohydrin process. This process involves the following steps:1. Acetone and hydrogen cyanide are first reacted in the presence of sulfuric acid to form acetone cyanohydrin.2. The acetone cyanohydrin is then hydrolyzed to form methacrylamide.3. Methacrylamide is further reacted with sulfuric acid to form methyl methacrylate.The overall reaction can be summarized as follows:Acetone + Hydrogen Cyanide → Acetone CyanohydrinAcetone Cyanohydrin + Water → MethacrylamideMethacrylamide + Sulfuric Acid → Methyl MethacrylateThis process is carried out in a series of reactors under controlled conditions to ensure high yield and purity of methyl methacrylate.

3. What are the applications of methyl methacrylate?

Methyl methacrylate is a versatile chemical compound with various applications. It is primarily used in the production of polymethyl methacrylate (PMMA), which is a transparent thermoplastic commonly known as acrylic glass. PMMA is widely used in the manufacturing of automotive parts, lighting fixtures, signage, and displays due to its excellent transparency, UV resistance, and impact strength. Methyl methacrylate is also used in the production of adhesives, coatings, and sealants. Its quick curing properties make it an ideal choice for bonding and sealing applications in construction and industrial sectors.
