Diethylethanolamine is prepared commercially by the reaction of diethylamine and ethylene oxide. [4] (C 2 H 5) 2 NH + cyclo(CH 2 CH 2)O → (C 2 H 5) 2 NCH 2 CH 2 OH. It is also possible to prepare it by the reaction of diethylamine and ethylene chlorohydrin. [5]
DEA is used as a surfactant and a corrosion inhibitor.It is used to remove hydrogen sulfide and carbon dioxide from natural gas.. Diethanolamine is widely used in the preparation of diethanolamides and diethanolamine salts of long-chain fatty acids that are formulated into soaps and surfactants used in liquid laundry and dishwashing detergents, cosmetics, shampoos and hair conditioners.

Ethylene oxide scrubber: After the gaseous stream from the main reactor, containing ethylene oxide (1–2%) and CO 2 (5%), is cooled, it is then passed to the ethylene oxide scrubber. Here, water is used as the scrubbing media which scrubs away majority of ethylene oxide along with some amounts of CO 2 , N 2 , CH 2 =CH 2 , CH 4 and aldehydes ...
Ethylamine is produced on a large scale by two processes. Most commonly ethanol and ammonia are combined in the presence of an oxide catalyst: CH 3 CH 2 OH + NH 3 → CH 3 CH 2 NH 2 + H 2 O. In this reaction, ethylamine is coproduced together with diethylamine and triethylamine.
Diethylamine is an organic compound with the formula (CH 3 CH 2) 2 NH. It is classified as a secondary amine. It is a flammable, volatile weakly alkaline liquid that is miscible with most solvents. It is a colorless liquid, but commercial samples often appear brown due to impurities. It has a strong ammonia-like odor.
MDEA is less reactive towards CO 2, but has an equilibrium loading capacity approaching 1 mole CO 2 per mole amine. [2] It also requires less energy to regenerate. [2] To combine the advantages of MDEA and the smaller amines, MDEA is usually mixed with a catalytic promoter such as piperazine, PZ, or a fast reacting amine such as MEA to retain reactivity, but lower regeneration costs.
Cialis has several common side effects, many of which also happen with other drugs used to treat ED, like sildenafil (generic Viagra®), vardenafil , and avanafil (Stendra®).
In the ethylene dichloride route, the initial product of this reaction is ethylenediamine. [3] In the presence of excess ethylene dichloride, the initial ethyleneamine is extended by one ethylene unit. The terminal alkyl chloride reacts with ammonia to give the amine, and the polyamine chain can be extended further in this fashion.
