CIS-5-NORBORNENE-EXO-2,3-DICARBOXYLIC ANHYDRIDE Chemical Properties,Usage,Production

Chemical Properties

Off-white to tan solid

Uses

cis-5-Norbornene-exo-2,3-dicarboxylic anhydride is used as an organic chemical synthesis intermediate.

Application

Cis-5-norbornene-exo-2,3-dicarboxylic anhydride is an important curing agent for epoxy resins. During the curing process, the anhydride groups react with the epoxy groups to form a cross-linked network structure. Using this compound as a curing agent can significantly improve the heat resistance, mechanical strength, and electrical insulation properties of epoxy resins. Therefore, it is widely used in the manufacture of high-performance coatings, adhesives, composite materials, and packaging materials for electronic components.

Synthesis

129-64-6

2746-19-2

A method for preparing high-purity cis-5-norbornene-exo-2,3-dicarboxylic anhydride by microwave reaction is disclosed. The method comprises the following steps: using cis-5-norbornene-endo-2,3-dicarboxylic anhydride as a raw material, as follows:(1) In a 1L reaction flask, 200g of cis-5-norbornene-endo-2,3-dicarboxylic anhydride and 600mL of toluene were added, stirred and mixed, and transferred to a microwave autoclave. The reaction system was warmed up to 200 °C and heated under microwave radiation at 100-200 GHz for 8 min; (2) After the reaction, the reactor was cooled to 110 °C and stirred continuously in an oil bath for 30 min to promote crystallization. Subsequent cooling to room temperature, filtration and drying were performed to obtain the target product cis-5-norbornene-exo-2,3-dicarboxylic anhydride 160.2 g; the yield was 80.1%; the purity was 98.2%; and the content of oxidized impurities was 0.06%.
