Diamine
(Redirected from Diamines)
Diamine is a type of organic compound that contains two amino groups. Diamines are used as monomers to prepare polyamides, polyimides, and polyureas. The term diamine refers to both primary diamines, with formula NH2–R–NH2 and secondary diamines with formula HN(R)–R–NR2.
Structure and properties
Diamines are commonly categorized as aromatic, aliphatic, and cyclic. Some common examples of diamines include ethylenediamine, hexamethylenediamine, and phenylenediamine.
Diamines can exist as single isomers, or as mixtures of isomers. For example, phenylenediamine often refers to a mixture of the ortho and para isomers of 1,2-diaminobenzene.
Applications
Diamines play a significant role in the production of many useful chemicals. They are commonly used as monomers to prepare polyamides, polyimides, and polyureas. In addition, they are also used in the production of epoxy resins.
Health effects
Exposure to diamines can cause a variety of health effects, such as skin and eye irritation, respiratory problems, and in severe cases, can lead to organ damage. Therefore, proper handling and safety measures should be taken when working with these chemicals.
