2-Ethylimidazole Usage And Synthesis

Chemical Properties

White to slightly yellow flakes

Uses

2-Ethylimidazole is a selective catalyst for epoxy and urethanes reactions. 2-Ethylimidazole is used for two components epoxy systems; for modification of epoxy resins and for preparation of polyurethanes.
2-Ethylimidazole has been used as internal standard in the quantification of 4-(5-)methylimidazole (4MI) in coffee by GC-MS method.
Reactions of [RuH(CO)CI(PPh3)3] have been carried out with imidazole, 2-methylimidazole, 2-ethylimidazole and pyrazole in the presence of suitable anions [BF4- ,BPh4-,ClO4-,&PF6-] The reaction products are found to be cationic and have been characterized by elemental analyses, IR, UV/vis and NMR spectral studies.
Microwave plasma reaction of 2-ethylimidazole on poly(dimethylsiloxane) surface has been investigated.

Uses

2-Ethylimidazole is used as internal standard in the quantification of 4-(5-)methylimidazole (4MI) in coffee by GC-MS method. It is a versatile intermediate used as a building block for active ingredients as well as in epoxy curing.

General Description

Microwave plasma reaction of 2-ethylimidazole on poly(dimethylsiloxane) surface has been investigated.
