化学的特性
colourless liquid
使用
1-Methoxy-2-propanol acts as a good biological indicator.
一般的な説明
A colorless liquid. Flash point near 89°F. Less dense than water. Contact irritates skin, eyes and mucous membranes. Prolonged exposure to vapors may cause coughing, shortness of breath, dizziness and intoxication. Vapors heavier than air. Used as a solvent and as an antifreeze agent.
空気と水の反応
Highly flammable. Soluble in water. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979 p.151-154, 164].
反応プロフィール
1-Methoxy-2-propanol is a methoxy alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
危険性
Flammable, moderate fire risk. TLV: 100
ppm; STEL 150 ppm.
健康ハザード
VAPOR: Irritating to eyes, nose, and throat. LIQUID: Irritating to skin and eyes.
火災危険
FLAMMABLE. Flashback along vapor trail may occur. Vapor may explode if ignited in an enclosed area.
安全性プロファイル
Moderately toxic by
intravenous route. Mildly toxic by ingestion,
inhalation, and skin contact. Human
systemic effects by inhalation: general
anesthesia, nausea. A skin and eye irritant.
An experimental teratogen. Many glycol
ethers have dangerous human reproductive
effects. Very dangerous fire hazard when
exposed to heat or flame; can react with
oxidizing materials. To fight fire, use foam,
CO2, dry chemical. When heated to
decomposition it emits acrid smoke and
irritating fumes. Used as a solvent and in
solvent-sealing of cellophane. See also

GLYCOL MONOMETHYL ETHER.
職業ばく露
Propylene glycol monomethyl ether is
used as a solvent for coatings; cellulose esters and acrylics;
acrylics dyes; inks, and stains. It may also be used as
a heat-transfer fluid.
輸送方法
UN3092 1-Methoxy-2-propanol, Hazard Class: 3;
Labels: 3-Flammable liquid.
Advantages
1-Methoxy-2-propanol has been used as an antifreeze material, principally in ebullient cooling systems and in some heavy-duty diesel engines. Because an azeotrope is formed between 1-methoxy-2-propanol and water, freeze protection also is provided in the vapor phase in ebullient cooling applications. On the other hand, 1-methoxy-2-propanol is more volatile and is more readily expelled along with water vapor through the crankcase vent system. 1-Methoxy-2-propanol also maintains lower metal temperatures than comparative glycolbased coolants. This was an advantage in rotary engines.
不和合性
Vapor 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, epoxides, acid chlorides, acid anhydrides, isocya-
nates, aluminum, and copper. Hygroscopic (i.e., absorbs
moisture from the air). May slowly form reactive peroxides
during prolonged storage or on exposure to air and light.
廃棄物の処理
Dissolve or mix the
material with a combustible solvent and burn in a chemical
incinerator equipped with an afterburner and scrubber.
All federal, state, and local environmental regulations must
be observed.
