Methyl-5-norbornene-2,3-dicarboxylic anhydride Chemical Properties,Usage,Production
Chemical Properties
clear light yellow oily liquid
Uses
Methyl-5-norbornene-2,3-dicarboxylic anhydride is used as a curing agent in epoxy resins and in the preparation of vertically aligned and penetrated carbon nanotube/polymer film. It serves as an intermediate in polyesters, alkyd resins and plasticizers. It is also used in electrical laminating and filament-winding. Further, it is used in the preparation of methyl nadimides endcapped resins based on tris(3-aminophenyl)phosphine oxide. It is utilized in the flame retarding treatment.
General Description
additional information see 45359 Epoxy Embedding Medium kit
Flammability and Explosibility
Non flammable
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.]
