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/Al2O3 catalysts modified with cinchonidine has been studied.

Adsorption and desorption of trans-2-methyl-2-pentenoic acid (MPeA) in dichloromethane (CH(2)Cl(2)) were investigated by using in situ attenuated total reflection infrared (ATR-IR) spectroscopy. A liquid flow-through spectroscopic cell allowed for high quality spectra to be obtained from deposited thin films of
Heterogeneous asymmetric hydrogenation and deuteration of 2-methyl-2-pentenoic acid over Pd supported catalysts: proton/deuterium exchange.
