Imidazole is a five-membered aromatic heterocyclic compound containing two meta-nitrogen atoms in the molecular structure. The unshared electron pair of the 1-position nitrogen atom in the imidazole ring participates in the cyclic conjugation, and the electron density of the nitrogen atom is reduced, making this nitrogen The hydrogen on the atom easily leaves as a hydrogen ion. Therefore, imidazole has weak acidity and can form salts with strong bases. The basicity of imidazole is slightly stronger than that of pyrazole and pyridine, and it is stable to acid and has antioxidant properties. Derivatives of imidazole are widely found in nature. Such as histamine, histidine, benzimidazole and so on.
The main purpose
Imidazole can be used as a curing agent for epoxy resins, can improve the mechanical properties of products such as bending, stretching and compression, improve the electrical properties of insulation, and improve the chemical properties of chemical resistance. It is widely used in computers and electrical appliances; as a copper anti-rust Used in printed circuit boards and integrated circuits;
Imidazole can be used as a pharmaceutical raw material, used to manufacture antifungal drugs, antifungal agents, hypoglycemia treatment drugs, artificial plasma, trichomonas treatment drugs, bronchial asthma treatment drugs, anti-spotting agents, etc.; used as pesticide raw materials, used for boric acid Synergist for preparations, preparation of insecticides and fungicides; in addition, imidazole is also used as a raw material for urea-formaldehyde resin curing agents, photographic drugs, adhesives, coatings, rubber vulcanizing agents, antistatic agents, etc.; organic synthesis intermediates .
