In general, the production of ethanolamines, which is a class of amines, consists of three stages
- Synthesis
- Ammonia distillation
- Isolation of different species of ethanolamines
This product is created by the reaction between ethylene oxide and aqueous ammonia solution, which causes the formation of diethanolamine and triethanolamine. The ratio of these substances can be controlled by the stoichiometry of the reactants. This reaction is hot and prevents the temperature from rising and reaching the flash point.
C2H4O + NH3 → H2NCH2CH2OH
Ethylene oxide reacts slowly with ammonia and water is added to improve the reaction rate. In anhydrous processes, a catalytic reactor with ion exchange resins or zeolites and clays is used. All of these processes take place in the liquid phase and the pressure in the reactor is so high that it prevents ethylene oxide and ammonia from evaporating at the reaction temperature.
Monoethanolamine Safety Tips (MSDS)
It is corrosive to the skin and prolonged contact with it is harmful to the kidneys and liver.
Swallowing and vapors of this substance causes damage to the respiratory system, stomach, mouth and esophagus and also causes problems such as: nausea, vomiting, diarrhea, dizziness, thirst, shock-like state, drop in blood pressure, slow pulse, anesthesia, coma , Fainting and fainting.
This compound can form an explosive mixture with air at temperatures above 85 ° C.
Consider all safety aspects when working with these materials.
