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