DIMETHYL ETHANOLAMINE

Phosphatidyl ethanolamines —ch2ch2nh3 Large amounts in animals, plants and microorganisms Old trivial name is cephalin. Methyl and dimethyl ethanolamine derivatives also occur... 

As a function of N,N-dimethyl ethanolamine concentration, the pKslymerization rate passed throi h a maximum, as shown in F. 2. Such behaviour parallels that observed for photoreduction of fluorenone by other tertiary amines, e.g. the quantum yield for photoreduction by triethyiamine has been measured (5) as 0.09 in neat amine, 0.9 in... 

Morlex DMEA. [Unmn Carbide] N,N-Dimethyl ethanolamine corrosion control agent in boiler water and steam systems. 

The synthesis of the free base has been described from a 5-aryl-2-pentanone [34], its keto group being transformed into a 1,3-oxazolidine with a,a-dimethyl ethanolamine, the free NH then reacts firstly with phosgene and secondly with imidazole (Scheme 17.3).
