Primarily a corrosion inhibitor in steam and condensate lines due to its neutralizing carbonic acid and scavenging oxygen, diethylaminoethanol is prepared in mass quantity for commercial and industrial use. It is a skin, eye, and respiratory irritant, and OSHA has set occupational exposure limits for workers to 10 ppm over the average eight hour work day. It is a clear liquid that is also used as a neutralizing amine for industrial coatings and as an intermediate for various surfactants. DEAE is a popular choice for treating process water in boilers and steam heat systems since it neutralizes corrosive agents within the system and scavenges CO2. It also provides an ideal solution for adjusting the pH balance of process water due to its vapor pressure and vapor-liquid distribution properties. DEAE is also used in pharmaceuticals and various ink production processes, though its primary application remains water treatment solutions.
