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]
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 ...
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.
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.
Oxychlorination is employed in the conversion of ethylene into vinyl chloride. In the first step in this process, ethylene undergoes oxychlorination to give ethylene chloride: CH 2 =CH 2 + 2 HCl + ½ O 2 → ClCH 2 CH 2 Cl + H 2 O. Oxychlorination is of special importance in the making of 1,2-dichloroethane, which is then converted into vinyl ...
Diethylenetriamine (abbreviated Dien or DETA) and also known as 2,2’-Iminodi(ethylamine) [2]) is an organic compound with the formula HN(CH 2 CH 2 NH 2) 2.This colourless hygroscopic liquid is soluble in water and polar organic solvents, but not simple hydrocarbons.
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.

Several million tons of ethylene glycol are produced annually by the hydration of oxirane, a cyclic compound also known as ethylene oxide: C 2 H 4 O + H 2 O → HO–CH 2 CH 2 –OH. Acid catalysts are typically used. [2]
