Dry the amine with anhydrous K2CO3 or KOH, and fractionally distil it. [Beilstein 4 IV 1424.]
Inhalation of the vapor or mist can cause irritation to the upper respiratory tract. Asthmatic symptoms have been reported. Extremely irritating; may cause permanent eye injury. Corrosive; will cause severe skin damage with burns and blistering. Ingestion may cause damage to the mucous membranes and gastrointestinal tract.
ChEBI: A tertiary amine that is ethanolamine having two N-methyl substituents.
DIMETHYLAMINOETHANOL is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. N,N-Dimethylethanolamine may react vigorously with oxidizing materials.
Air & Water Reactions
Flammable. Partially soluble in water and less dense than water.
A clear colorless liquid with a fishlike odor. Flash point 105°F. Less dense than water. Vapors heavier than air. Toxic oxides of nitrogen produced during combustion. Used to make other chemicals.
