吉草酸メチル 化学特性,用途語,生産方法

• 外観

  無色澄明の液体

• 溶解性

  水に難溶。エタノール, エーテルに易溶。エタノール及びアセトンに極めて溶けやすく、水にほとんど溶けない。

• 説明

  Methyl pentanoate, commonly known as methyl valerate, is the methyl ester of pentanoic acid (valeric acid) with a fruity odor.
  Methyl pentanoate is commonly used in fragrances, beauty care, soap, laundry detergents at levels of 0.1 – 1 % .
  In a very pure form ( greater than 99.5 % ) it is used as a plasticizer in the manufacture of plastics.
  It is also used as an insecticide.

• 化学的特性

  Methyl valerate has a pungent, green-fruity odor that is apple- and pineapple-like with a corresponding flavor at 1 0 - 5 0 ppm. May be prepared by direct esterification of the valeric acid with methanol in the presence of concentrated H2S04; note: this ester hydrolyzes readily.

• 天然物の起源

  Reported found in small amounts in the essential oil from the fruits of Ananas sativus Schult. Also reported present in apple, coffee, honey, kiwi, melon, papaya, pineapple, strawberry, tea, wine, blackberry, baked potato, olive, starfruit, passion fruit, soursop, Bourbon vanilla, mountain papaya and naranjilla fruit.

• 使用

  Methyl valerate can be used:
  
  • In the preparation of lankacidin C 8-valerate.
  • As a reactant to synthesize bis(2,2,2-trifluoroethyl) 2-oxoalkylphosphonates.
  • As a substrate in the fluorination reactions of unactivated C(sp³)H bonds using decatungstate photocatalyst and N-fluorobenzenesulfonimide.
  
  

• 主な応用

  Methyl valerate is primarily used in flavor compositions, although it occasionally finds application in certain phases of perfumery (masking, household products of certain type, etc.).
  Its Apple-like character is useful in fruit complexes where diffusive power is desirable (chewing gum, etc.) and it performs very well in Pineapple or fantasy flavors.

• 製造方法

  By direct esterification of valeric acid with methanol in the presence of concentrated H2SO4. Note: This ester hydrolyzes readily

• 一般的な説明

  Clear colorless to yellowish oily liquid.

• 空気と水の反応

  Highly flammable. Insoluble in water.

• 反応プロフィール

  METHYL VALERATE is an ester. Esters react 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 of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. METHYL VALERATE reacts with oxidizing agents, bases and acids.

• 火災危険

  METHYL VALERATE is flammable.
