Quick Summary

A diamine is a chemical compound that contains two amino groups. These compounds are significant in various industrial applications. For instance, aromatic diamines are used as developers in photography, and some polyfunctional amines serve as pharmaceuticals, such as ephedrine and epinephrine.12

Amines, in general, are utilized as corrosion inhibitors, antioxidants for rubber, and stabilizers for explosives. They also play a role in the synthesis of important products like analgesics, antihistamines, solvents, and synthetic fibers such as Kevlar. Diazonium salts, which are prepared from primary amines, are crucial in the dye industry for creating a wide range of colors. Diamine dyes are a specific type of direct dye that contains a diamine element.234

However, certain diamines (e.g., alkyl-aryl paraphenylene diamines) prevent cracking, probably by competing with the C=C bonds in rubber for reaction with ozone. These antiozonants “bloom” to the surface and react there, protecting the rubber. A few percent of an antiozonant is therefore commonly included in the mix…
