FAQ - Technical & Supply Chain
-
Q:
Is BDEA the same as N-Butylethanolamine (NBEA)?
A: No. BDEA is N-Butyldiethanolamine CAS 102-79-4, a tertiary alkanolamine with two hydroxyethyl groups and formula C₈H₁₉NO₂. NBEA has CAS 111-75-1 and only one hydroxyethyl group, so the two products have different reactivity, water solubility, and application behavior. -
Q:
Which specifications matter for N-Butyldiethanolamine?
A: Compare assay by GC, water content, color/APHA, density, refractive index, and amine value. Typical industrial BDEA has assay about 99% or higher, low water content, and a clear colorless to pale yellow appearance, but the final limits should match the intended metalworking, coating, or synthesis use. -
Q:
What is N-Butyldiethanolamine used for?
A: BDEA is mainly used as a corrosion inhibitor and lubricity additive in water-based metalworking fluids, as a rust preventative/VCI component, and as a neutralizing amine in waterborne coatings, inks, and resins. It is also used in blended amine gas treatment and as an intermediate for surfactants or quaternary ammonium compounds. -
Q:
How should BDEA be stored and handled?
A: Store in tightly closed, compatible containers in a cool, dry, ventilated area away from strong acids, oxidizers, isocyanates, and copper or copper alloys. BDEA is corrosive to skin and eyes, so use chemical-resistant gloves, eye protection, and adequate ventilation when handling. -
Q:
What are the key physical properties of N-Butyldiethanolamine?
A: BDEA is a clear, colorless to pale yellow viscous liquid with formula C₈H₁₉NO₂ and molar mass about 161.24 g/mol. Common sources list density around 0.968-0.994 g/cm³ at 20 °C, boiling point about 270-275 °C, melting point near -45 °C and refractive index about 1.460-1.468; confirm the offered grade because limits vary.
