Triethanolamine is a colorless, transparent and viscous liquid at room temperature, with a slight ammonia smell. It is hygroscopic and can absorb moisture and carbon dioxide in the air. Can be freely mixed with water and alcohol, soluble in chloroform, slightly soluble in benzene and ether. The pH of 0.1moI/L solution is 10.5. There is a danger of burning when exposed to high heat, open flame or contact with oxidants. Its aqueous solution is corrosive.
Instructions on the compatibility of triethanolamine:
Triethanolamine is a tertiary amine containing hydroxyl groups and has a typical reaction between tertiary amines and ethanol.
Triethanolamine can react with inorganic acids to form crystalline salts and esters. Reacting with higher fatty acids, triethanolamine can form water-soluble salts and have soap properties.
Triethanolamine can also react with copper to form a double salt. It may change color and precipitate when encountering heavy metal salts.
Triethanolamine can react with reagents such as thionyl chloride, and the hydroxyl group can be replaced by halogen. The reaction product is very toxic, similar to nitrogen mustard.
