Beschreibung
2-Methylvaleric acid has a powerful, pungent, acrid odor. Below
10 ppm the flavor is agreeable, sour, and oily. At higher concentrations,
the flavor is too acidic. May be prepared by catalytic
oxidation of 2-methyl pentanealdehyde; from 2-chloropentane
with sodium and C02 under pressure; by decarboxylation of
methyl propyl malonic acid; two optically active iosmers are
known.
Chemische Eigenschaften
2-Methylvaleric acid has a powerful, pungent, acrid odor. At concentrations below 10 ppm, it has an agreeable, sour,
oily flavor. At higher concentrations the flavor becomes disagreeable because it is too acidic.
Occurrence
Reported found in coffee, wine, cheese, papaya, baked potato, pepper, lamb, rum, tea, mango and cherimoya
Verwenden
2-Methylvaleric acid is used to produce plasticizers, vinyl
stabilizers, metallic salts, and alkyd resins.
