WebDIETHANOLAMINE (DEA) General MW: 105.1 gmol-1 CAS No.: 111-42-2 EINECS No.: 203-868-0 IUPAC name: 2,2'-iminodiethanol Diethanolamine (DEA; CAS 111-42-2) contains one secondary amine and two alcohol groups. DEA is a highly viscose liquid with a freezing point of 28 ºC. It is mainly used for gas sweetening and in the Webroom temperature; diethanolamine is a crystal-line solid. All ethanolamines absorb water and carbon dioxide from the air and are infinitely miscible with water andalcohols. The freezing points of all ethanolamines can be lowered considerably by the addition of water. Some physical properties of ethanolamines are listed in Table 1. 2.1.2 ...
