It finds application in various fields such as textile lubricants, polishes, detergents and in personal care products. It is also involved in electrostatic automotive coatings and in acid gas scrubbing. Further, it serves as an intermediate in polymers and pharmaceuticals. In addition to this, it is used as a solvent in the natural gas-processing industry. | | 使用 | Textile chemicals, pharmaceuticals. | | 定義 | ChEBI: An ethanolamine compound having an N-methyl substituent. | | 調製方法 | Monomethylethanolamine is manufactured by reacting ethylene
oxide and methylamine with external cooling. | | 一般的な説明 | 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. | | 空気と水の反応 | Soluble in water. | | 反応プロフィール | 2-Methylaminoethanol 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. 2-Methylaminoethanol may react with oxidizing materials. | | 健康ハザード | Exposure can cause irritation of eyes, nose and throat. | | 火災危険 | Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as nitrogen oxides and carbon monoxide, may be formed when involved in fire. | | 安全性プロファイル | 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. |
