1,4-ジクロロ-2-ブテン (cis-, trans-混合物) 化学特性,用途語,生産方法
外観
無色～うすい黄色～うすい黄赤色透明液体
用途
化学プロセス用の中間体.(SIDS(2006))
化学的特性
The 1,4-dichloro-2-butenes are colorless
liquids. Some have a distinct odor. (cis-isomer)
一般的な説明
A clear colorless liquid. Burns, though may be difficult to ignite. Corrosive to tissue. Denser than water and insoluble in water. Vapors heavier than air. Used to make other chemicals.
空気と水の反応
Highly flammable. Reacts slowly with water to form hydrochloric acid. Insoluble in water.
反応プロフィール
Halogenated unsaturated aliphatic compounds, such as TRANS-1,4-DICHLORO-2-BUTENE, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
健康ハザード
Inhalation of vapor irritates nose and throat. Contact with eyes causes intense irritation and tears. Contact of liquid with skin causes severe blistering and dermatitis. Ingestion causes severe irritation of mouth and stomach.
火災危険
Special Hazards of Combustion Products: Decomposition vapors contain phosgene and hydrogen chloride gases; both are toxic and irritating.
化学反応性
Reactivity with Water Reacts slowly to form hydrochloric acid; Reactivity with Common Materials: Corrodes metal when wet; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
安全性プロファイル
Confirmed carcinogen
with experimental carcinogenic and
neoplastigenic data. Poison by ingestion,
inhalation, and intravenous routes.
Moderately toxic by skin contact. An experimental teratogen. Other experimental
reproductive effects. Mutation data
reported. A severe skin and eye irritant.
When heated to decomposition it emits
toxic fumes of Cl-. See also

職業ばく露
DC occurs as a by-product in chloroprene manufacture and may be used as a chemical
intermediate
輸送方法
UN3384 Toxic by inhalation liquid, flammable, n.
o.s. with an LC50 ≦ 1000 ml/m3 and saturated vapor
concentration ≧to 10 LC50, Hazard class: 6.1; Labels:
6.1-Poisonous materials, 3-Flammable liquid, Technical Name
Required, Inhalation Hazard Zone B. UN2920 Corrosive
liquids, flammable, n.o.s., Hazard class: 8; Labels: 8-Corrosive
material, 3-Flammable liquid. The code “D” identifies proper
shipping names which are appropriate for
describing materials for domestic transportation but may be
inappropriate for international transportation under the provisions of international regulations, e.g., IMO, ICAO). An alternate proper shipping name may be selected when either
domestic or international transportation is involved
不和合性
Vapors 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. (cis-isomer): Reacts slowly with water forming hydrogen chloride. Attacks metals and may form other,
more dangerous materials; attacks some plastics.
廃棄物の処理
High-temperature incineration
with hydrochloric acid scrubbing. Consult with environmental regulatory agencies for guidance on
acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with
EPA regulations governing storage, transportation, treatment, and waste disposal.
