• 化学的特性

  Propargyl alcohol is a colorless liquid with a geranium-like odor.

• 使用

  Propargyl alcohol is a solvent stabilizer that is useful as an intermediate in organic synthesis, an electroplating brightener additive. It is useful 3-carbon fragment in acetylene coupling reactions, It undergoes Pd-catalyzed O-coupling with alcohols to give the corresponding 1-methoxyallyl ethers.

• 調製方法

  Propargyl alcohol is the major commercially available acetylenic primary alcohol. Propargyl alcohol is a byproduct of butynediol production. In the usual high-pressure butynediol process, about 5% of the product is propargyl alcohol. Some processes give higher proportions of propargyl alcohol.

• 定義

  ChEBI: A terminal acetylenic compound that is prop-2-yne substituted by a hydroxy group at position 1.

• 一般的な説明

  A dark liquid with a "fishlike" odor. Less dense than water. Flash point 90°F. Boiling point is 239°F. Corrosive and contact may severely irritate skin, eyes, and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used to make other chemicals.

• 空気と水の反応

  Highly flammable. Soluble in water.

• 危険性

  Flammable, moderate fire risk. Toxic by ingestion, inhalation, and skin absorption. Eye irri- tant, liver and kidney damage.

• 健康ハザード

  May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to 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

  Flammable/combustible material. May be 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

  Poison by ingestion, skin contact, and subcutaneous routes. Moderately toxic by inhalation. A central nervous system depressant. A skin and mucous membrane irritant. Mutation data reported. Flammable liquid and dangerous fire hazard when exposed to heat or flame; can ignite. To fight fire, use foam, CO2, dry chemical. Potentially explosive reactions with alkalies (when dried), sulfuric acid. Ignites on contact with phosphorus pentaoxide. Violent reaction with mercury(Ⅱ) sulfate + sulfuric acid + water (at 70°C). Incompatible with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes. Used as a corrosion inhibitor, solvent stabilizer, soil fumigant, and chemical intermediate. See also ACETYLENE COMPOUNDS.

• 職業ばく露

  Propargyl alcohol is used as a corrosion inhibitor, soil fumigant; solvent, stabilizer, and chemical intermediate.

• 貯蔵

  2-Propyn-1-ol is stored in stainless steellined, glass-lined, or phenolic-lined tanks ordrums. Unlined steel containers may be usedif free of rust. Aluminum, rubber, and epoxymaterials should not be used. Use protectivewear when handling. Wash thoroug.

• 輸送方法

  UN1986 Alcohols, flammable, toxic, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, 6.1- Poisonous materials, Technical Name Required. UN2929 Toxic liquids, flammable, organic, n.o.s., Hazard class: 6.1;

• 純化方法

  The commercial material contains a stabiliser. An aqueous solution of propargyl alcohol can be concentrated by azeotropic distillation with butanol or butyl acetate. Dry it with K2CO3 and distil it under reduced pressure, in the presence of about 1% succinic acid, through a glass helices-packed column. [Beilstein 1 IV 2214.]

• 不和合性

  Vapor may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, perox- ides, permanganates, perchlorates, chlorine, bromine, fluo- rine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, phosphorus pentoxide. May polymerize under the influence of heat, oxidizers, peroxides, light. Attacks many plastics.

• 廃棄物の処理

  Wear protective eye protec- tion, gloves and clothing to prevent any reasonable proba- bility of skin or eye contact. Safety equipment suppliers/ manufacturers can provide recommendations on the most protective glove/clothing material for your operation. All protective clothing (suits, gloves, footwear, headgear) should be clean, available each day, and put on before work. Contact lenses should not be worn when working with this chemical. Wear splash-proof chemical goggles and face shield when working with liquid full facepiece respiratory protection is worn. Employees should wash immediately with soap when skin is wet or contaminated. Provide emergency showers and eyewash.
