Kinetics of the solvent-free hydrogenation of 2-methyl-3-butyn-2-ol over a structured Pd-based catalyst

Albert Renken, Lioubov Kiwi, Rocio Micaela Crespo Quesada, Martin Grasemann

The solvent-free selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) was studied over a Pd/ZnO structured catalyst and compared to its behavior in water-assisted conditions. The catalytic behavior was correlated with the s ...

High-pressure effects on the Diels-Alder reaction in room temperature ionic liquids

Paul Joseph Dyson, Gabor Laurenczy, Ana Vidis

The effect of pressure on the Diels-Alder reaction was examined in room temperature ionic liquids, followed by high-pressure FT-IR spectroscopy using pressures up to 150 MPa. Pressure enhances the kinetic sensitivity of the reaction. The kinetic effec ...
