Infobox references

Diethylethanolamine can be used as a precursor chemical to procaine. It can be reacted with 4-aminobenzoic acid to make procaine.

Applications

Diethylethanolamine is used as a corrosion inhibitor in steam and condensate lines by neutralizing carbonic acid and scavenging oxygen.

Preparation

Diethylethanolamine is prepared commercially by the reaction of diethylamine and ethylene oxide.

(C₂H₅)₂NH + cyclo(CH₂CH₂)O → (C₂H₅)₂NCH₂CH₂OH

It is also possible to prepare it by the reaction of diethylamine and ethylene chlorohydrin.

Safety

Diethylethanolamine is an irritant to the eyes, skin, and respiratory system. The Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health have set occupational exposure limits for workers handling the chemical at 10 ppm (50 mg/m³) over an eight-hour workday.
