Verwenden
2-Ethyl-4-methylimidazole can be used as a:
- cross-linker for epoxy resins to synthesize network polymers with improved thermal resistance and physical properties.
- curing agent for polysiloxane episulfide resin (PSER).
- catalyst to promote curing of blends of hyperbranched aromatic epoxy polymer and bisphenol F diglycidyl ether.
Verwenden
Curing epoxy-resin systems.
Application
2-Ethyl-4-methylimidazole is an important synthetic intermediate. It is used as an intermediate in pharmaceuticals, agrochemicals, dyes, textile auxiliaries, pigments and other organic chemicals. It can be used as a basic ingredient in other active ingredients, as a catalyst in chemical reactions, and in the curing of epoxy resins.
synthetische
2-Ethyl-4-methylimidazole was prepared as follows: diamine and propionitrile have a cyclization reaction sequentially at the temperature of 80-110 DEG C and 120-140 DEG C under the catalysis of a catalyst; a product after the cyclization reaction has a dehydrogenation reaction through raney nickel at the temperature of 170-200 DEG C, and 2-ethyl-4-methylimidazole is obtained.
Definition
ChEBI: 5K8XI641G3 is a member of imidazoles.
Flammability and Explosibility
Non flammable
