• 化学的特性

  colourless liquid

• 使用

  (^+)-4-Methyl-2-pentanol is employed as a solvent in organic synthesis, dyes and stains, natural resins and waxes. It is an additive to surface coatings. It finds applications in the manufacture of lube oil additives, zinc dialkyldithiophosphate, brake fluids. It is the precursor to some plasticizers and frother in mineral flotation. It acts as a corrosion inhibitor and also utilized in the characterization of volatile fraction of mono varietal wines and tar sand mining processes.

• 調製方法

  Methyl isobutyl carbinol is prepared commercially as a byproduct of the synthesis of methyl isobutyl ketone.

• 一般的な説明

  A clear colorless liquid. Flash point 120°F. Less dense than water. Vapors heavier than air.

• 空気と水の反応

  Flammable. Soluble in water.

• 反応プロフィール

  4-Methyl-2-pentanol is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. 4-Methyl-2-pentanol is incompatible with strong oxidizers .

• 危険性

  Moderate fire risk, explosive limits in air 1– 5.5%. Eye and upper respiratory tract irritant, and central nervous system impairment.

• 健康ハザード

  Vapor irritates eyes and nose; may cause anesthesia. Prolonged contact with liquid causes irritation and cracking of skin; also irritates eyes.

• 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.

• 化学反応性

  Reactivity with Water: No reaction; Reactivity with Common Materials: No reaction; 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

  Moderately toxic by ingestion, skin contact, and intraperitoneal routes. Mildly toxic by inhalation. A skin and severe eye irritant. Inhalation of high concentrations can cause anesthesia. Flammable liquid when exposed to heat or flame; can react with oxidizing materials. A moderate explosion hazard when exposed to heat or flame. To fight fire, use alcohol foam. When heated to decomposition it emits acrid smoke and fumes.

• 職業ばく露

  MIBC is used as a solvent; in the formulation of brake fluids; as an intermediate in organic synthesis.

• 輸送方法

  UN2053Methyl isobutyl carbinol, Hazard Class: 3; Labels: 3-Flammable liquid

• 純化方法

  Wash the 2-pentanol with aqueous NaHCO3, dry and distil it. Purify it further by converting it to the phthalate ester by adding 120mL of dry pyridine and 67g of phthalic anhydride per mole of alcohol, purifying the ester and steam distilling it in the presence of NaOH. The distillate is extracted with ether, and the extract is dried and fractionally distilled. [Levine & Walti J Biol Chem 94 367 1931, Beilstein 1 IV 1717.]

• 不和合性

  Vapor 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 acids, peroxysulfuric acid, strong bases, caustics, aliphatic amines; isocyanates. Contact with alkali metals produces hydrogen gas. Permissibl

• 廃棄物の処理

  Incineration; other, more flammable solvent may be added.
