物理的性質
Colorless, flammable liquid with an ammonia-like odor. Experimentally determined detection and
recognition odor threshold concentrations were 400 μg/m
3 (85 ppb
v) and 1.2 mg/m
3 (250 ppb
v),
respectively (Hellman and Small, 1974).
使用
N-Ethylmorpholine is a component of the buffer used in basic peptide separation through anion-exchange chromatography. Further, it acts as a catalyst in the preparation of polyurethane foam.
製造方法
N-Ethylmorpholine is synthesized by the reaction of morpholine with bromoethane.
一般的な説明
N-Ethylmorpholine appears as a colorless liquid with a strong ammonia-like odor. Severely irritates skin, eyes, and mucous membranes. Moderately soluble in water and less dense than water. Flash point 83°F.
空気と水の反応
Highly flammable. Moderately soluble in water .
反応プロフィール
N-Ethylmorpholine can react vigorously with oxidizing materials. N-Ethylmorpholine dissolves LiAlH4.
危険性
Irritant to skin and eyes, absorbed by
skin. Flammable, moderate fire risk. Toxic by skin
absorption.
健康ハザード
Exposure can cause irritation of eyes, nose and throat. Contact with eyes may result in foggy vision and seeing halos around lights.
安全性プロファイル
oison by intravenous
route. Moderately toxic by ingestion. Mildly
toxic by inhalation. A skin and severe eye
irritant. A very dangerous fire hazard when
exposed to heat or flame; can react
vigorously with oxidzing materials. To fight
fire, use alcohol foam, foam, CO2, dry
chemical. When heated to decomposition it
emits toxic fumes of NOx.
職業ばく露
Primary irritant (without allergic reaction). This material is used as a catalyst in polyurethane
foam production. It is a solvent for dyes and resins. It is
used as an intermediate in surfactant, dye, pharmaceutical,
and rubber chemical manufacture
環境運命予測
Chemical/Physical. Releases toxic nitrogen oxides when heated to decomposition (Sax and
Lewis, 1987).
At an influent concentration of 1,000 mg/L, treatment with GAC resulted in an effluent
concentration of 467 mg/L. The adsorbability of the carbon used was 107 mg/g carbon (Guisti et
al., 1974).
輸送方法
UN2920 Corrosive liquids, flammable, n.o.s.,
Hazard class: 8; Labels: 8-Corrosive material, 3-Flammable
liquid. UN1993 Flammable liquids, n.o.s., Hazard Class: 3;

不和合性
May form explosive mixture with air.
Incompatible with oxidizers (chlorates, nitrates, peroxides,
permanganates, perchlorates, chlorine, bromine, fluorine,etc.); contact may cause fires or explosions. Keep away
from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Corrodes some metals. Unless inhibited,
violent polymerization can occur from heat, sunlight, and
contact with strong oxidizers permanganates, perchlorates, chlorine, bromine, fluorine,
etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, and epoxides. Attacks some plastics, rubber and
coatings
廃棄物の処理
Controlled incineration (oxides of nitrogen are removed from the effluent gas by scrubbers and/or thermal devices).
