Amines

Amines are organic compounds that contain nitrogen atoms with a lone pair. Basically, they are derived from ammonia (NH₃) in which one or more hydrogen atoms is replaced by an alkyl or aryl group, and so they are known as alkylamines and arylamines respectively. Amines are used as solvents, intermediates, catalysts, emulsifiers, stabilizer, and scrubbing agent in various industries such as, manufacturing of polyurethane, pharmaceuticals, agrochemicals, polymers and other chemicals in products like detergents, wax removers, etc.
Monoethanolamine (MEA) is a simple ethanolamine with one primary amine and one alcohol group. It is a colorless liquid with a mild ammonia odor. MEA is mainly used in sweetening natural gas and coal gas, and as soap or amides in heavy-duty detergents. Monoethanolamine is also used in the production of ethylene amines.
Diethanolamine (DEA) contains a secondary amine and two alcohol groups. It is a viscous liquid. It is mainly used for gas sweetening and in the manufacture of light-duty detergents and shampoos and can be cyclized to morpholine. It is also used in metalworking lubricant additives, bath and shower products, cement, textile auxiliary, textile softeners and hair care.
Triethanolamine (TEA) is a colorless, water clear, viscous liquid. TEA is soluble in all proportions with water & alcohols. TEA is a hygroscopic material with liquid ammonical odor. Triethanolamine is also known as a TEA, is used as intermediate in the manufacture of surface-active agent, textile specialties, antirust compounds, waxes, polishes, herbicides, petroleum demulsifier, cement additives and cutting oils.
