DESCRIPTION
2-Diethylaminoethanol is the common name for the substance systematically identified as 2-(diethylamino)ethan-1-ol.
2-Diethylaminoethanol is identified by CAS Number 100-37-8 and EC Number 202-845-2.
2-Diethylaminoethanol has the molecular formula C₆H₁₅NO.
2-Diethylaminoethanol has a molecular weight of approximately 117.19 g/mol.
Structurally, 2-Diethylaminoethanol contains one hydroxyethyl group attached to a tertiary nitrogen atom.
The nitrogen atom is additionally bonded to two ethyl groups.
The molecule contains a primary alcohol but no nitrogen–hydrogen bond.
2-Diethylaminoethanol therefore combines alcohol reactivity with tertiary-amine basicity.
The tertiary nitrogen of 2-Diethylaminoethanol accepts a proton from mineral and organic acids.
Protonation produces diethylaminoethanol salts with increased ionic character and water compatibility.
The hydroxyl group can undergo esterification, etherification, urethane formation, and other alcohol reactions.
The tertiary nitrogen can undergo quaternization with suitable alkylating reagents.
2-Diethylaminoethanol normally appears as a clear, colorless, hygroscopic liquid.
The material possesses a characteristic strong amine-like odor that may be perceived as ammoniacal or nauseating.
High-purity product can darken through prolonged exposure to air, heat, reactive contaminants, or unsuitable metal surfaces.
Color-sensitive grades require controlled storage and careful distillative purification.
2-Diethylaminoethanol has a boiling point near 163°C.
Its melting or freezing point is reported near −70°C.
The substance therefore remains liquid across a broad range of normal handling temperatures.
Its comparatively high boiling point does not eliminate vapor exposure because measurable evaporation occurs at room temperature.
2-Diethylaminoethanol has a relative density of approximately 0.88–0.89.
The liquid is consequently lighter than water.
The substance is miscible with water.
Its water miscibility reflects the combined effects of the hydroxyl group, tertiary nitrogen, and protonation equilibria.
2-Diethylaminoethanol has a reported log octanol–water partition coefficient near 0.46.
This value indicates greater aqueous compatibility than strongly hydrophobic organic amines.
The neutral free base can nevertheless partition into compatible organic phases.
Acidification shifts the substance toward a protonated, more strongly water-associated form.
Published vapor-pressure values differ among authoritative compilations.
The NIOSH Pocket Guide lists approximately 1 mmHg, while the international safety card reports 2.8 kPa at 20°C.
This discrepancy makes grade-specific or experimentally verified vapor-pressure data preferable for detailed process design.
Both sources agree that harmful airborne contamination can occur and that effective ventilation is required.
2-Diethylaminoethanol has a closed-cup flash point near 52°C.
The material is therefore flammable and can form ignitable vapor–air mixtures during warm processing.
Its reported autoignition temperature is approximately 250°C.
Closed equipment and effective ventilation are required above the flash-point region.
Published explosive-limit ranges also differ according to source and test conditions.
The international safety card reports approximately 1.9–28% by volume in air.
The NIOSH Pocket Guide lists approximately 6.7–11.7% by volume.
Process design should rely on conservative current data applicable to the actual operating temperature, pressure, and test method.
2-Diethylaminoethanol is a basic organic compound.
Neutralization with strong acids is exothermic.
The material reacts with strong acids and strong oxidizing agents.
Incompatible reactions can cause rapid heat generation, pressure, splashing, decomposition, or fire.
2-Diethylaminoethanol can be manufactured by reaction of diethylamine with ethylene oxide.
The reaction opens the ethylene-oxide ring and forms the hydroxyethyl group.
Water can accelerate the reaction, while excess diethylamine helps suppress formation of higher-ethoxylated products.
The crude product is purified through removal of excess amine, thermal treatment, water separation, and distillation.
Continuous manufacturing routes employ controlled reaction temperatures, pressure, residence time, and rapid heat removal.
Published process descriptions include tubular reactors and reaction temperatures extending from moderate conditions to approximately 180°C.
Distillation separates low-boiling starting materials and higher-boiling ethoxylated impurities from the desired product.
Color-stable material requires control of oxygen, temperature history, water, carbonyl impurities, and high-boiling by-products.
Important process-related impurities can include residual diethylamine, water, higher-ethoxylated amino alcohols, low-boiling oxygenated compounds, and thermally generated color bodies.
Residual diethylamine affects odor, assay, alkalinity, and downstream reaction stoichiometry.
Water can interfere with moisture-sensitive esterification, isocyanate, epoxy, and coating processes.
High-boiling impurities can remain in products prepared without effective fractional distillation.
2-Diethylaminoethanol is capable of neutralizing acid-functional polymers.
Formation of ammonium carboxylate groups increases the water dispersibility of compatible coating binders.
Evaporation or deprotonation during curing can reduce the ionic character of the dry film.
Final coating behavior depends on neutralization degree, resin chemistry, film temperature, humidity, and residual amine.
2-Diethylaminoethanol combustion produces nitrogen oxides and other irritating or toxic fumes.
Fire can also generate carbon monoxide, carbon dioxide, smoke, and incompletely oxidized amine vapors.
Containers exposed to heat may release flammable vapor or fail through pressure buildup.
Firefighting runoff should be prevented from carrying concentrated amine into drains or natural waters.
