N,N-Diethylethanolamine - Nature

Open Data Verified Data

colorless liquid, with slightly ammonia flavor. Soluble in alcohol, water, ketone, ethylene glycol, glycerol and glycol ether. It is difficult or insoluble in non-polar solvents such as aliphatic hydrocarbons and the like. An azeotrope may be formed with water. Hygroscopic, placed in the air can absorb carbon dioxide. It is easy to change color in long-term storage or temperature environment at 40 °c. Flammable, fire, high-energy combustion caused by explosion. Reactions with strong oxidants can cause combustion, the products of which are carbon monoxide, carbon dioxide and nitrogen oxides.

N,N-Diethylethanolamine - Safety

Open Data Verified Data

It is corrosive to eyes, skin and respiratory mucosa. Can be absorbed by the respiratory tract and digestive tract as well as the skin, affecting the nervous system. The skin and eyes were washed with a large amount of running water immediately after contact. Store in a cool, ventilated warehouse, should be away from the fire, heat sources, to prevent direct sunlight. It cannot be stored and transported together with oxidant and acid substances.

N,N-Diethylethanolamine - Preparation

The chloroethanol and sodium hydroxide are reacted at 105 ℃ to generate ethylene oxide, which is passed into diethylamine solution for reaction. After the low boiling substance is separated under normal pressure, the N,N-diethylethanolamine finished product is obtained by distillation under reduced pressure. At present, most production plants directly use ethylene oxide as raw material.
