Methacrylic anhydride Usage And Synthesis
| Description | Methacrylic anhydride is a reactive monomer used primarily as a monomer in the preparation of polymers, particularly poly(methacrylic acid) and its copolymers. The reaction mechanism involves the formation of covalent bonds between methacrylic acid and acetic anhydride molecules, resulting in the formation of a novel compound. The newly formed compound then undergoes a series of reactions including hydrolysis and polymerisation. Methacrylic anhydride produces polymers with good chemical and thermal stability, which are used in a wide range of applications in various industries such as bio-renewable resins, pH-sensitive hydrogels, thermoset plastics, coatings, adhesives and plastics. |
| Chemical Properties | Methacrylic anhydride is a colorless transparent liquid which reacts with water exothermically. It can also react with hydroxyl- and amino-groups present in some organic compounds leading to covalent attachment of methacryloyl moieties. |
| Uses | Methacrylic anhydride is a reactive monomer used for the preparation of different type of monomers under mild reaction conditions. It finds applications in light-curing coatings, cross-linked materials like synthetic resin. It acts as an intermediate for the preparation of fibers and resins. |
| Preparation | To synthesize Methacrylic anhydride, sodium methacrylate (1 mol), propionyl chloride (3 mol), and a polymerization inhibitor (0.1 mol) were added to a reaction kettle. The mixture was heated to 90-100 ℃ and refluxed for 8 hours. Methacrylic anhydride was then obtained by distilling and collecting fractions at 100-105 ℃. The yield of the product was 98.33%. |
| Application | Methacrylic anhydride can be used as a starting material to synthesize:
Methacrylated chondroitin sulfate pH-sensitive hydrogels by copolymerization reaction. These hydrogels can be used in drug delivery systems.
High-performance lignin-based thermosets.
Gel polymer electrolyte, which is then integrated with the cathode to form high-performance lithium-ion batteries.
Methacrylic anhydride can be also used as a precursor to synthesize bio-renewable resins for composite applications. For example, it can be used to prepare soybean oil and a eugenol-based resin system. This resin possesses high thermal stability, and good mechanical properties, which makes it a suitable matrix for the pultrusion process. |
