An Examination of γ-valerolactone Ring Opening and Decarboxylation in Multiphase System and Over Various Solid Acid Catalysts
… carbon source for industrial applications. γ-valerolactone (GVL) is an example of biomass-derived platform chemicals that provides multiple commercial potentials. Of interest here is the acid-catalyzed ring opening of GVL to form pentenoic acid (PEA) isomers and following decarboxylation to …

Hidrogenação de ácido levulínico a gama-valerolactona empregando fosfetos de metais de transição suportados em sílica
… evaluated for levulinic acid hydrogenation to γ- valerolactone: Ni2P, CoP, MoP, WP and Fe2P. The catalysts were prepared in two steps: phosphate synthesis by incipient wetness followed by calcination, and phosphide synthesis by in situ temperature programmed reduction. The samples were …

Photoionization Mass Spectrometry and Photoelectron-Photoion Coincidence (PEPICO) Spectroscopy Studies of Select Biofuel Molecules
… photoionization mass spectrometry studies on γ-valerolactone (GVL). The photoionization cross section of GVL and some suspected combustion products are measured. In addition, several dissociative ions are determined. Theoretical calculations are used to support all alignments. This data is vital …

Investigating the Interaction of Chitin in Organic Electrolyte Solutions Using Molecular Dynamics
… dimethyl carbonate, propylene carbonate and γ-valerolactone, three structurally similar bio-based solvents. The solvation of a (GlcNAc)2Me2 monomer was also studied in this project via radial distribution functions, interaction energies and hydrogen bond analyses, as to support the results …
