Production method of monoethanolamine
Monoethanolamine is obtained from the reaction between ammonia and ethylene oxide. This reaction produces diethanolamine and triethanolamine in addition to monoethanolamine. The production ratio of different products can be adjusted by changing the stoichiometry of the reaction. This reaction is thermal and should prevent the temperature from rising and reaching the flash point. Ethylene oxide reacts slowly with ammonia, adding water to speed up the reaction. In processes without water, a fixed bed catalytic reactor with ion exchange resins or zeolite and clay is used. The whole process takes place in the liquid phase and the pressure in the reactor is high enough to prevent ethylene oxide and ammonia from evaporating at the reaction temperature. Monoethanolamine is recommended as a substance for making alkanolamides because of its reaction with fatty acid or coconut oil. As a result of its properties, this product is used in various industrial sectors such as…
