Poison by
intraperitoneal route. Moderately toxic by
ingestion and subcutaneous routes. A
corrosive irritant to skin, eyes, and mucous
membranes. Flammable when exposed to
heat, flame, or oxidizers. To fight fire, use
alcohol foam. When heated to
decomposition it emits toxic fumes such as
NOx. See also AMINES and ALCOHOLS. | [Hazardous Substances Data]

| Hazard Information | Back Directory | [General Description]
A clear colorless liquid. Flash point 165°F. Less dense than water and soluble in water. Vapors are heavier than air. Produces toxic oxides of nitrogen during combustion. Used to make other chemicals. | [Reactivity Profile]
METHYLETHANOLAMINE(109-83-1) 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. This compound may react with oxidizing materials. | [Air & Water Reactions]
Soluble in water. | [Health Hazard]
Exposure can cause irritation of eyes, nose and throat. | [Fire Hazard]
Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as nitrogen oxides and carbon monoxide, may be formed when involved in fire. | [Chemical Properties]
viscous colourless or light yellow liquid | [Definition]
ChEBI: An ethanolamine compound having an N-methyl substituent. | [Production Methods]
Monomethylethanolamine is manufactured by reacting ethylene
oxide and methylamine with external cooling. |
