Description
Colorless, hygroscopic liquid base that is used as a vapor phase corrosion inhibitor. Diethylaminoethanol (DEAE) is added to the water in boilers in steam humidification systems to minimize pipe corrosion. It is also used as an alkalizing agent in HVAC systems to neutralize carbonic acids. When DEAE is used in an open ventilation system, it can deposit on all available surfaces including works of art. DEAE produces an oily residue that can soften varnishes.
Synonyms and Related Terms
DEAE; 2-diethylaminoethanol; beta-diethylaminoethyl alcohol; 2-hydroxytriethyl amine; N,N-diethylethanolamine; diethyl ethanolamine
Risks
- Combustible. Flash point = 52 C.
- Toxic by ingestion and skin absorption.
- Contact causes irritation.
