Product Details
Description |
Methyl-5-norbornene-2,3-dicarboxylic anhydride, also known as nadic methyl anhydride (MNA), is a versatile liquid cyclic anhydride primarily used as a curing agent in epoxy resins. |
Uses |
Its application extends to the production of vertically aligned and penetrated carbon nanotube/polymer films, and it serves as an intermediate in the synthesis of polyesters, alkyd resins, and plasticizers. MNA is utilized in electrical laminating, filament winding, and the preparation of methyl nadimides endcapped resins based on tris(3-aminophenyl)phosphine oxide, and it also finds use in flame-retardant treatments. MNA is prepared by a diene addition reaction, where maleic anhydride is heated with methylcyclopentadiene. This compound's reactivity and utility in producing high-performance materials make it valuable in various advanced industrial applications, particularly in the fields of electronics, automotive, and aerospace. Its inclusion in insulation for generators, automotive motors, transformers, and rotors underscores its importance in enhancing material properties such as chemical resistance, thermal stability, and durability. |
Flammability and Explosibility |
Nonflammable |
Purification Methods |
Purify the anhydride by thin layer chromatography on Al2O3 (previously boiled in EtOAc) and eluted with hexane/*C6H6 (1:2) then recrystallise it from *C6H6/hexane. The free acid has m 118.5-119.5o. [Miranov et al. Tetrahedron 19 1939 1963, Beilstein 17/11 V 199.] |
