• Beschreibung

  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.

• Chemische Eigenschaften

  clear colorless liquid

• Chemische Eigenschaften

  Methyl valerate has a pungent, green-fruity odor, apple and pineapple-like. It has a similar flavor at 10 to 50 ppm

• Chemische Eigenschaften

  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.

• Occurrence

  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.

• Verwenden

  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.
  
  

• synthetische

• Allgemeine Beschreibung

  Clear colorless to yellowish oily liquid.

• Air & Water Reaktionen

  Highly flammable. Insoluble in water.

• Reaktivität anzeigen

  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.

• Brandgefahr

  METHYL VALERATE is flammable.

• Flammability and Explosibility

  Flammable
