Ethanolamine, also known as monoethanolamine, is a colorless, viscous liquid with a slightly ammoniacal odor. It is used in a variety of industries, such as the detergent, pharmaceutical, and fuel industries. In the detergent industry, it is used as a surfactant, antifoaming agent, and pH adjuster. In the pharmaceutical industry, it is used as an intermediate in the manufacturing of drugs, as well as an emulsifying agent and a solvent. In the fuel industry, it is used as a corrosion inhibitor and a stabilizer.
When rubber is exposed to ethanolamine, it can cause swelling, discoloration, and cracking. Swelling occurs when ethanolamine molecules penetrate the rubber, causing it to become softer and expand. Discoloration occurs when ethanolamine molecules interact with the rubber molecules and cause a visible change in color. Cracking may occur if the rubber is exposed to ethanolamine for too long, as the ethanolamine molecules can cause the rubber to become brittle and crack.
