General Properies
Diethanol amin, or DEA, is a white solid in its pure form. When it contacts with air, it becomes a colorless, viscose liquid due to its hydophile tendencies. It has two functional groups; dial and amin. Like most amins, it is a weal alkali. It can be dissolved in water thanks to the functional groups it possesses.
Diethanol amin can be used in many fields, from cosmetics to surface active chemicals, and it classifies as carciogenic for humans.
Production
Diethanol amin is produced from the reaction of ethylene oxide and ammonia in its gas phase.
Applications
DEA is used to acquire foaming effects in cosmetic business. It is also a surface active subtance and it is a corrosion blocker. It is commonly used in refining process of oil.
Diethanol amin is also a raw material for certain industrial chemicals.
Safety Measures and Toxic Values
Diethanol amin is hazardous if swallowed. Repeated exposure causes damage in internal organs. It is also extremely irritant for eyes and skin. Recent studies indicate that diethanol amin is dangerous for underwater life.
For this reason, DEA must be stored in a well-aired envronment. And it must undergo proper purification process before it is dropped to sewage.
