化学的特性
colourless liquid
物理的性質
Colorless liquid with a faint, pleasant odor. Experimentally determined detection and recognition
odor threshold concentrations were 300 μg/m
3 (60 ppb
v) and 700 μg/m
3 (130 ppb
v), respectively
(Hellman and Small, 1974). Nagata and Takeuchi (1990) reported an odor threshold concentration
of 49 ppb
v.
使用
Solvent for nitrocellulose, oils, and resins;
retards “blushing” in lacquers, varnish removers,
wood stains, textiles, and leather.
一般的な説明
A clear colorless liquid with a pleasant odor. Flash point of 120°F. Less dense than water. Vapors are heavier than air.
空気と水の反応
Flammable. Slightly soluble in water.
反応プロフィール
Mixing Ethylene glycol monoethyl ether acetate in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, oleum, and vinyl acetate, NFPA 1991.
危険性
Toxic by ingestion and skin absorption.
Toxic by skin absorption.
健康ハザード
Vapors irritate nose and eyes in high concentrations. Liquid irritates skin in prolonged or repeated contact.
火災危険
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
安全性プロファイル
Moderately toxic by
ingestion and intraperitoneal routes. A skin
and eye irritant. An experimental teratogen.
Other experimental reproductive effects.
Flammable liquid when exposed to heat or
flame; can react with oxidizing materials.
Moderate explosion hazard in the form of
vapor when heated. Mild explosions have
occurred at the end of disullations. To fight
fire, use alcohol foam, CO2, dry chemical.
When heated to decomposition it emits acrid smoke and irritating fumes. See also
GLYCOL ETHERS.
職業ばく露
This material is used as a solvent for
many different purposes; including for nitrocellulose and
other resins. Used in automobile lacquers to retard evaporation and impart a high gloss.
環境運命予測
Biological. Bridié et al. (1979) reported BOD and COD values of 0.74 and 1.76 g/g using
filtered effluent from a biological sanitary waste treatment plant. These values were determined
using a standard dilution method at 20 °C for a period of 5 d. The ThOD for 2-ethoxyethyl acetate
is 1.82 g/g.
Chemical/Physical. At an influent concentration of 1,000 mg/L, treatment with GAC resulted
in an effluent concentration of 342 mg/L. The adsorbability of the carbon used was 132 mg/g
carbon (Guisti et al., 1974).
輸送方法
UN1172 Ethylene glycol monoethyl ether acetate, Hazard Class: 3; Labels: 3-Flammable liquid
純化方法
Shake the ethoxy-ethane with anhydrous Na2CO3, filter and distil it in a vacuum. Redistillation can then be carried out at atmospheric pressure. [Dunbar & Bolstad J Org Chem 21 1041 1956, Beilstein 2 IV 214.]
不和合性
May form explosive mixture with air.
Incompatible with strong acids; strong alkalies; nitrates.
Violent reaction with oxidizers. May form unstable peroxides.
Softens many plastics. Attacks some plastics, rubber, and
coatings
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.
