プロピオン酸 メチル 化学特性,用途語,生産方法

• 外観

  無色〜ほとんど無色, 澄明の液体

• 溶解性

  水に微溶。エタノール, エーテルに易溶。エタノール及びジエチルエーテルに極めて溶けやすく、水に溶ける。

• 説明

  Methyl propionate, also known as methyl propanoate, is a chemical compound with the molecular formula C₄H₈O₂. It is a volatile ester with a sweet, fruity, rum-like odor.

• 化学的特性

  Methyl propionate is colorless liquid with a sweet, fruity, rum-like odor.

• 天然物の起源

  Reported found in guava, honey, melon, pineapple, raspberry, blackberry, strawberry, cheddar cheese, cooked beef, coffee, soy protein, durian (Durio zibethinus), starfruit, plum brandy, cherimoya, kiwifruit, naranjilla, mussels and rooibus tea (Aspalathus linearis)

• 使用

  Methyl propionate is used as a solvent for cellulose nitrate and lacquers, and as a raw material for the production of paints, varnishes and other chemicals such as methyl methacrylate.
  Due to its fruity smell and taste, it is also used in fragrances and flavoring.

• 製造方法

  Methyl propionate can be prepared by esterification of propionic acid with methanol. Industrially, it is prepared by the reaction of ethylene with carbon monoxide and methanol in the presence of nickel carbonyl.

• 調製方法

  Methyl propionate is produced by the direct esterification of propionic acid with methanol in the presence of concentrated sulfuric acid .

• 一般的な説明

  A clear colorless liquid. Flash point 28°F. Density about the same as water. Vapors heavier than air. May irritate skin, eyes, and mucous membranes. Used for flavoring and as a solvent.

• 空気と水の反応

  Highly flammable. Soluble in water.

• 反応プロフィール

  Methyl propionate reacts with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction with caustic solutions. Flammable hydrogen is generated with alkali metals and hydrides.

• 危険性

  Flammable, dangerous fire risk, explosivelimits in air 2.5–13%.

• 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. 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

  Moderately toxic by ingestion. Mildly toxic by inhalation. A skin irritant. A very dangerous fire hazard when exposed to heat, flame, or oxidizers. Explosive in the form of vapor when exposed to heat or flame. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.

• 職業ばく露

  Used as a solvent; and in making paints, lacquers, and varnishes. Also used in flavorings and fragrances

• 輸送方法

  UN1248 Methyl propionate, Hazard Class: 3; Labels: 3-Flammable liquid.

• 純化方法

  Wash the ester with saturated aqueous NaCl, then dry it with Na2CO3 and distil it from P2O5. (This removes any free acid and alcohol.) It has also been dried with anhydrous CuSO4. [Beilstein 2 IV 104.]

• 不和合性

  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, epoxides. Keep away from heat and moisture.
