• 使用

  cis-1,2-Dichloroethylene (cis-1,2-DCE) is generally used in the preparation of various enediynes for Bergman cyclization. Applications include the synthesis of:
  
  • 2-(6-substituted 3(Z)-hexen-1,5-diynyl)anilines to prepare corresponding substituted carbazoles.
  • (Z)-1-aryl-3-henen-1,5-diynes to obtain the corresponding aryl substituted benzotriazoles.
  
  
  It is used as a linker to synthesize boron-dipyrromethene (BODIPY)-based photosensitizer for photodynamic therapy (PDT). cis-1,2-DCE can also be used as a precursor to synthesize intermediates of sporolide B.

• 一般的な説明

  A clear colorless liquid with an ether-like odor. Flash point 36-39°F. Denser than water and insoluble in water. Vapors heavier than air. Used in the making of perfumes.

• 空気と水の反応

  Highly flammable.Slightly soluble in water.

• 反応プロフィール

  1,2-DICHLOROETHYLENE and potassium hydroxide forms chloroacetylene, which is explosive and spontaneously flammable in air. CIS-1,2-DICHLOROETHYLENE is highly toxic, Rutledge, p134(1968).

• 健康ハザード

  May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

• 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. May polymerize explosively when heated or involved in a fire. 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

  Mildly toxic by ingestion and inhalation. In high concentration it is irritating and narcotic. Has produced liver and kidney injury in experimental animals. Mutation data reported. Sometimes thought to be nonflammable, however, it is a dangerous fire hazard when exposed to heat or flame. Reaction with solid caustic alkalies or their concentrated solutions produces chloracetylene gas, whch ignites spontaneously in air. Reacts violently with N2O4, KOH, Na, NaOH. Moderate explosion hazard in the form of vapor when exposed to flame. Can react vigorously with oxidizing materials. To fight fire, use water spray, foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of Cl-. See also VINYLIDENE CHLORIDE and CHLORINATED HYDROCARBONS, ALIPHATIC.

• 職業ばく露

  Primary irritant (w/o allergic reaction). 1,2-Dichloroethylene is used as a solvent for waxes, resins, and acetylcellulose. It is also used in the extraction of rubber, as a refrigerant; in the manufacture of pharmaceuticals and artificial pearls; and in the extraction of oils and fats from fish and meat.

• 輸送方法

  UN1150 Dichloroethylene, Hazard Class: 3; Labels: 3-Flammable liquid.

• 純化方法

  Purify it by careful fractional distillation, followed by passage through neutral activated alumina. Also by shaking with mercury, drying with K2CO3 and distilling from CaSO4. Stabilise it with 0.02% of 2,6-di-tert-butyl-p-cresol. [Beilstein 1 IV 707.]

• 不和合性

  May form explosive mixture with air. Attacks some plastics, rubber, and coatings. 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. Gradual decomposition results in hydrochloric acid formation in the presence of ultraviolet light or upon contact with hot metal or other hot surfaces. Reacts with strong bases; potassium hydroxide; difluoromethylene, dihypofluoride, nitrogen tetroxide (explosive); or copper (and its alloys) producing toxic chloroacetylene which is spontaneously flammable on contact with air. Attacks some plastics and coatings.

• 廃棄物の処理

  Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced. 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.
