イソシアン酸 n-ブチル 化学特性,用途語,生産方法

• 外観

  無色～黄色, 澄明の液体

• 溶解性

  水で分解。水で分解する。

• 用途

  有機合成原料。

• 用途

  農薬用原料、有機合成原料

• 使用上の注意

  不活性ガス封入

• 化学的特性

  Colorless to faintly yellow liquid

• 使用

  n-Butyl isocyanate is used as an acylatingagent in the Friedel–Crafts reaction to produce amide.

• 定義

  ChEBI: An isocyanate having a butyl group attached to the nitrogen.

• 一般的な説明

  A clear, colorless liquid with a pungent odor. Flash point 68°F. Very toxic by ingestion, and may also be toxic by skin absorption and inhalation. Vapors heavier than air. Less dense than water and insoluble in water. Produces toxic oxides of nitrogen during combustion.

• 空気と水の反応

  Highly flammable. Extremely slow decomposition by water. Less dense than water and insoluble in water.

• 反応プロフィール

  Isocyanates and thioisocyanates are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969].

• 危険性

  Strong irritant to eyes and skin.

• 健康ハザード

  n-Butyl isocyanate exhibits low inhalationtoxicity and relatively higher oral toxicity.This is in contrast to the aromatic isocyanates. The toxic effects are nausea, dyspnea, insomnia, coughing, and chest pain.Such symptoms, however, are much lessmarked than those of methyl isocyanate.
  LC50 value, inhalation (mice): 680 mg/m³
  LD50 value, oral (mice): 150 mg/kg
  There is no report of any carcinogenic orteratogenic study of this compound.

• 火災危険

  HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

• 安全性プロファイル

  A poison by ingestion and intravenous routes. Mddly toxic by inhalation. A powerful irritant to eyes, skin, and mucous membranes. A flammable liquid. See also CYANATES and NITROGEN MONOXIDE.

• 職業ばく露

  N-Butyl isocyanate is used as a reagent in organic synthesis; used as intermediates in production of pharmaceuticals, carbamate and urea insecticides, and fungicides. It is also used in the production of sulfonylurea antidiabetic drugs

• 輸送方法

  UN2485 n-Butyl isocyanate, Hazard Class: 6.1; Labels: 6.1—Poison Inhalation Hazard, 3—Flammable liquid. Hazard, Inhalation Hazard Zone B. PGI.

• 不和合性

  Vapor may form explosive mixture with air. Isocyanates are highly flammable and reactive with many compounds, even with themselves. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Reaction with moist air, water or alcohols may form amines and insoluble polyureas and react exothermically, releasing toxic, corrosive or flammable gases, including carbon dioxide; and, at the same time, may generate a violent release of heat increasing the concentration of fumes in the air. Incompatible with amines, aldehydes, alkali metals, ammonia, carboxylic acids, caprolactum, alkaline materials, glycols, ketones, mercaptans, hydrides, organotin catalysts, phenols, strong acids, strong bases, strong reducing agents such as hydrides, urethanes, ureas. Elevated temperatures or contact with acids, bases, tertiary amines, and acylchlorides may cause explosive polymerization. Contact with metals may evolve flammable hydrogen gas. Attacks some plastics, rubber and coatings. May accumulate static electrical charges, and may cause ignition of its vapors

• 廃棄物の処理

  Dispose of contents and container to an approved waste disposal plant. Use a licensed professional waste disposal service to dispose of this material. Caution: this chemical is highly flammable with a low flash point (,20C). 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.
