Description |
Nadic anhydride, with its versatile reactivity and applications, plays a significant role in the field of organic synthesis and materials science. Its use in curing epoxy resins highlights its importance in the production of high-performance materials with desirable properties such as strength, chemical resistance, and electrical insulation. |
| Chemical Structure | Nadic anhydride, also known as 5-norbornene-2,3-dicarboxylic anhydride, is an organic acid anhydride derivative of norbornene. |
|
Uses |
Used in curing epoxy resins, resulting in a high-strength epoxy system. Exhibits excellent chemical resistance to solvents and chemical attacks. Functions as an excellent electrical insulator. |
| Physical State | Typically exists as a colorless liquid. |
| Synthesis | Synthesized by the reaction of maleic anhydride with cyclopentadiene, often obtained from the cleavage of dicyclopentadiene. |
| Alternative Name | Nadic methyl anhydride (NMA) is a liquid anhydride variant used to cure epoxy resins. |
| Intermediate for Endo-2,3-Norbornanedicarboximide | Serves as an intermediate in the preparation of Endo-2,3-Norbornanedicarboximide, which, in turn, is utilized in the synthesis of piperidinylbenzisoxazole antipsychotic drugs. |
| Hydrolysis | Undergoes hydrolysis when exposed to water, forming the corresponding acid. |

The esters were obtained from acidic derivatives of nadic anhydride and glycidyl methacrylate. The addition reaction of glycidyl methacrylate and the acidic compound was carried out in the presence of basic catalyst—tetraethylammonium bromide.
Nadic anhydride has not been previously investigated by vibrational spectroscopy. This paper demonstrates that with state-of-the-art inelastic neutron scattering spectra it is possible to successfully analyse complex systems that have not been studied before.
Scheme 2 exemplifies the reaction of polycondensation of nadic anhydride 3 and ethylene glycol 4 under organometallic catalysis. A hindered phenol-based stabilizer was added to …
