Chemical Properties
CLEAR VISCOUS LIQUID
General Description
A clear colorless liquid with an ammonia-like odor. Corrosive to tissue. Combustible, but may be difficult to ignite. Less dense than water. Vapors heavier than air. Toxic oxides of nitrogen produced during combustion. Used to make other chemicals.
Reactivity Profile
AMINOETHYLETHANOLAMINE(111-41-1) is an amine and alcohol. 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. This chemical is hygroscopic.
Air & Water Reactions
Water soluble. Hygroscopic.
Health Hazard
Skin contact will cause mild irritation; eye contact will cause more severe irritation.
Potential Exposure
Used to make textile finishing compounds, dyes, resins, rubber, insecticides, medicines, and oth
Fire Hazard
This chemical is combustible.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water or milk. Do not induce vomiting. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed.

Description
Aminoethylethanolamine is a component of colophony
in soldering flux, which may cause contact and
airborne contact dermatitis in workers in the electronic
industry or in cable jointers.
Purification Methods
Distil the amine twice through a Vigreux column (p 11). Redistil it from solid NaOH, then from CaH2. Alternatively, it can be converted to the dihydrochloride and recrystallised from water. It is then dried, mixed with excess of solid NaOH and the free base is distilled from the mixture. It is finally redistilled from CaH2. [Drinkard et al.
