Definition
ChEBI: 2-Methyl-2-pentenoic acid is a methyl-branched fatty acid. It is a conjugate acid of a 2-methyl-(2E)-pentenoate(1-).
Preparation
By distillation of 2-hydroxy-2-methylvaleric acid (cis-form).
Taste threshold values
Taste characteristics at 50 ppm: sour, acidic, sweaty, berry and fruit-like.
General Description
Adsorption and desorption of
trans-2-methyl-2-pentenoic acid in dichloromethane has been investigated by using
in situ attenuated total reflection infrared spectroscopy. Asymmetric hydrogenation of
trans-2-methyl-2-pentenoic acid in hexane over two well defined E-40692 and E-5220 Engelhard Pd/Al
2O
3 catalysts modified with cinchonidine has been studied.
